codes. You must follow these guidelines.
■Use care when handling the water softening
system. Do not turn upside down, drop, drag,
or set on sharp protrusions.
■Keep the salt hole cover in place on the softener
unless servicing the unit or refilling with salt.
■Water softening systems using sodium chloride
(salt) for regeneration add sodium to the water.
Persons on sodium restricted diets should consider
the added sodium as part of their overall intake.
Potassium chloride can be used as an alternative to
sodium chloride.
WARNING: Do not use with water that is
microbiologically unsafe or of unknown quality
without adequate disinfection before or after the
system.
PROPER INSTALLATION
This water softening system must be properly installed and located in accordance with the Installation
Instructions before it is used.
■Install or store where it will not be exposed to
temperatures below freezing or exposed to any
type of weather. Water freezing in the system will
break it. Do not attempt to treat water over 100°F.
■Softener resins may degrade in the presence of
chlorine above 1 ppm. If you have chlorine in
excess of this amount, you may experience
reduced resin life. In these conditions, you may
wish to consider purchasing a GE point-of-entry
household filtration system with a chlorine
reducing filter. Contact the GE Answer Center at
1-800-626-2000 for more information.
■Do not install in direct sunlight. Excessive sun heat
may cause distortion or other damage to non-
metallic parts.
■Properly ground to conform with all governing
codes and ordinances.
WARNING: Discard all unused parts and
packaging material after installation. Small
parts remaining after the installation could be
a choke hazard.
■Use only lead-free solder and flux for all sweat-
solder connections, as required by state and
federal codes.
■
The water softening system requires a minimum
water flow of three gallons per minute at the inlet.
Maximum allowable inlet water pressure is 125 psi.
If daytime pressure is over 80 psi, nighttime
pressure may exceed the maximum. Use a
pressure reducing valve to reduce the flow
if necessary.
Read and follow this Safety Information carefully.

Installation instructions.
CAUTION: Certain plumbing skills are needed for installation. If you are unsure about any part of the
installation of this product, consult a professional plumber.
Unpacking and Inspection
Be sure to check the entire softener for any shipping damage or parts loss. Also note damage to the shipping
cartons. Contact the transportation company for all damage and loss claims. The manufacturer is not
responsible for damages in transit.
Small parts, needed to install the softener, are on a skin-packed cardboard piece. To avoid loss of the small
parts, keep them on the skin-pack until you are ready to use them.
Important Installation Recommendations
Read entire manual. Failure to follow all guidelines and rules could cause personal injury or property damage.
• Before you begin installation, read these Installation Instructions completely. Then, obtain all the materials
and tools you will need to make the installation. Failure to properly install the softener voids the warranty.
• Check local codes. The installation must conform to them.
• In the Commonwealth of Massachusetts, Plumbing Code 248 CMR shall be adhered to.
Consult with your licensed plumber.
• Use only lead-free solder and flux for all sweat-solder connections, as required by state and federal codes.
• Connect the softener to the main water supply pipe before or ahead of the water heater. DO NOT RUN HOT
WATER THROUGH THE SOFTENER. Temperature of water passing through the softener must be less than 120° F.
• Use care when handling the softener. Do not turn upside down, drop, drag, or set on sharp protrusions.
• Maximum allowable inlet water pressure is 125 psi. If daytime pressure is over 80 psi, nighttime pressure may
exceed the maximum. Use a pressure reducing valve if necessary. (Adding a pressure reducing valve may
reduce the flow.)
• The softener works on 24 volt-60 Hz electrical power only. Be sure to use the included transformer.
Be sure the electric outlet and transformer are in an inside location to protect from wet weather.
• See Where to Install the Softener section for more details.
WARNING: Do not use with water that is microbiologically unsafe or of unknown quality without
adequate disinfection before or after the system. The water should be tested periodically to verify that
the system is performing satisfactorily.
Small parts remaining after the installation could be a choke hazard. Discard safely.

Plan How You Will Install the Softener
You must first decide how to run in and out pipes to the softener. Look at the house main water pipe at the
point where you will connect the softener. Is the pipe soldered copper, glued plastic, or threaded galvanized?
What is the pipe size?
WARNING: Use only lead-free solder and flux to prevent lead poisoning.
See Typical Installation Illustration, Fig.1. Use this as a guide when planning your particular installation.
Be sure to direct the incoming hard water supply to the softener valve inlet fitting. The valve is marked IN and OUT.
See below to help you prepare.
Where to Install the Softener
• Place the softener as close as possible to a sewer drain, or other acceptable drain point or standpipe.
• It is recommended to keep outside faucets on hard water to save soft water and salt.
• Do not install the softener in a place where it could freeze. Freeze damage is not covered by the warranty.
• Do not install the softener where it would block access to the water heater or access to the main water shutoff.
• Do not locate the brine tank more than 10 feet away from the resin tank.
• Put the softener in a place where water damage is least likely to occur if a leak develops. The manufacturer
will not repair or pay for water damage.
• A 120 volt electric outlet is needed to plug in the included transformer. The softener has a 10 foot power
cable. If the outlet is remote (up to 100 feet), use 18 gauge wire to connect. Be sure the electric outlet and
transformer are in an inside location, to protect from wet weather. Be sure the outlet is unswitched to prevent
accidental shutoff.
• If installing in an outside location, you must take the steps necessary to assure the softener, installation
plumbing, wiring, etc., are as well protected from the elements (sunlight, rain, wind, heat, cold),
contamination, vandalism, etc., as when installed indoors.
• Keep the softener out of direct sunlight. The sun’s heat may distort non-metallic parts and may damage
the electronics.
Tools and Materials Required for Installation
• In and out fittings included with the softener are 1″ (nominal) copper sweat tubes. To maintain full valve
flow, 1″ pipes to and from the softener fittings are recommended. You should maintain the same, or larger,
pipe size as the water supply pipe, up to the softener inlet and outlet.
• Use the included bypass valve to install the softener. The bypass valve allows you to turn off water to the
softener for servicing, but still have water in the house pipes. The in and out fittings referred to above
connect to the bypass valve with the included nuts and washers.
• Use copper, brass or galvanized pipe and fittings. Some codes may also allow CPVC plastic pipes.
• If additional drain hose is needed for salt tank drains, it can be ordered from GE Parts at 800.626.2002.
• Garden hose with female fitting is needed for valve drain (sufficiently long to reach suitable drain).
• If a rigid valve drain is needed to comply with plumbing codes, you can buy the parts needed to connect a
1/2″ copper tubing or plastic drain.
• Clean nugget or pellet water softener salt is needed to fill the brine tank, see Step 8 in the Step-by-Step
Installation Instructions.

FLOOR DRAIN
11⁄2″ air gap
CAUTION:
• Support inlet and outlet plumbing in some manner (use
pipe hangers) to keep the weight off of the valve fittings.
• Secure the resin tank to a stable structure to prevent it
from falling over.
• Locate the brine tank directly next to the resin tank.
4 Connect and run the valve drain hose:
to the valve drain fitting, as shown in Fig. 4.
• Be sure the installation surface is level and smooth. Sharp
objects under the brine tank may puncture it. If needed,
place the brine tank on a section of 3/4″ thick (minimum)
plywood. Then, place shims under the plywood as needed
to level the softener.
• Take a length of garden hose with female fitting and attach
IMPORTANT: Make sure the garden hose fitting fits
securely onto the threaded drain port.
• Locate the other end of the hose at a suitable drain point
(floor drain, sump, laundry tub, etc.) that terminates at the
sewer drain. Check and comply with local codes.
• Connect the black brine valve tube from the brinewell to
the venturi assembly on the valve, using the plastic nut
provided as shown in Fig. 5.
IMPORTANT: Use a high quality, thick-walled hose that
will not easily kink or collapse. The water softener will
not work if water cannot exit this hose during
regenerations.
3 Plumb IN and OUT pipes to and from softener:
CAUTION: Observe all of the following cautions as you
connect inlet and outlet plumbing.
• Tie or wire the hose in place at the drain point. High water
pressure will cause it to whip during the back-wash and fast
rinse cycles of regeneration. Also provide an air gap of at least
1–1/2 ″ between the end of the hose and the drain point. An air
gap prevents possible siphoning of sewer water into the
softener, if the sewer should back-up.
• Be sure incoming hard water supply is directed to the
softener valve inlet port. If house water flow is from the left,
use a plumbing cross-over as shown in Fig. 1.
• Do all sweat soldering before connecting pipes to the bypass
valve. Torch heat will damage plastic parts.
•
When turning threaded pipe fittings onto plastic fittings,
• If raising the drain hose overhead is required to get to the
drain point, do not raise higher than 8´ above the floor.
Elevating the hose may cause a back-pressure that could
reduce brine draw during regenerations.
use care not to cross-thread.
• Use pipe joint compound on all external pipe threads.

CAUTION: To avoid water or air pressure damage to softener
inner parts, be sure to do the following steps in exact order.
From valve outlet
A. Fully open 2 cold soft water faucets nearby the softener.
B. Place bypass valve in “bypass” position by pushing the
stem inward.
NOTE: If the softener is installed in a humid basement or
other damp area, it is better to fill the tank with less salt,
more frequently. Eighty to 100 lbs. of salt will last for several
months, depending on water hardness and family size.
C. Fully open the house main water pipe shutoff valve.
Observe a steady flow from both faucets opened in
Step A above.
Connect to electrical power:
D. Place bypass valve in the “service” position EXACTLY as
follows. KEEP SOFT WATER FAUCETS OPEN.
9
• Using the instruction sheet provided with the electronic
control, connect the wires from the valve to the electronic
control.
SLOWLY pull or slide the valve stem (OUT) toward
“service”, pausing several times to allow the softener to
pressurize slowly.
• If transformer wiring is not visible at the back of the
control head, remove control cover. DO NOT PULL ON OR
DISCONNECT WIRING. Locate the long wire with U shaped
connectors on one end. Route this wire through the rear
of the control housing. Replace the control cover.
E. After about 3 minutes, open a HOT water faucet for
1 minute, or until all air is expelled, then close.
NOTE: If water appears cloudy or has salty taste,
allow to run for several more minutes or until clear.
F. Close all water faucets.
• Fasten the 2 power cable lugs (“U” shaped connectors)
to the 2 screws on the transformer, and tighten the screws.
Then, plug the transformer into the electrical outlet.
G. Check your plumbing work for leaks and fix right away if
any are found. BE SURE TO OBSERVE PREVIOUS CAUTIONS.
• The softener works on 24 volt-60 Hz electric power. The
included transformer changes standard 120 volt AC house
power to 24 volts. Plug the transformer into a 120 volt outlet
only. Be sure the outlet is always live so it can not be switched
off by mistake.
Add water and salt to the brine tank:
8
• Lift the cabinet (brine tank) cover. Add about 3 gallons of
water into the tank. Do not add into the brinewell.
• Fill tank 1⁄3 to 1⁄2 full with NUGGET, PELLET or coarse SOLAR
water softener salt with a purity of 99.5% or higher. Do not
use rock, block, granulated, or ice cream-making salts or
salt with iron removing additives (except for Diamond
Crystal® Red•Out® brand salt.)

Step-by-step installation instructions.
Sanitizing Procedures
To complete the installation, do the following sanitizing procedures.
Care is taken at the factory to keep your water softener clean and sanitary. Materials used to make the softener
will not infect or contaminate your water supply and will not cause bacteria to form or grow. However, during
shipping, storage, installing and operating, bacteria could get into the softener. For this reason, sanitizing as
follows is suggested when installing.
NOTE: Sanitizing is recommended by the Water Quality Association for disinfecting.
Be sure to complete all installation steps, including timer programming.
1
Pour about 3/4 oz. of common 5.25% household bleach (Clorox, Linco, Bo Peep, White Sail, Eagle, etc.)
into the brinewell. Refer to illustration on page 8.
2
IMPORTANT: Press and hold for 3 seconds the faceplate TOUCH/HOLD button to start an immediate
3
regeneration. Recharge Now begins to flash in the display. The bleach is drawn into and through
the water softener.
If after sanitization water from house faucet tastes salty or has a slight color, this is a preservative from the
resin tank. Turn on the cold soft water faucets and drain for a few minutes or until clear.
4
NOTE: When the above sanitizing regeneration is over, your house COLD water supply is fully soft immediately.
However, your water heater is filled with hard water and as hot water is used, it will refill with soft water.
When all the hard water is replaced in the water heater, hot only and mixed hot and cold water will be fully
soft. If you want totally soft water immediately, after the above regeneration, drain the water heater until the
water runs cold.
WARNING: If you do drain the water heater, use extreme care as the hot water could cause burns.
Turn the water heater off prior to draining.

About the water softener system.
Service
When the water softening system is providing soft water, it is called “Service.” During service, hard water flows
from the house main water pipe into the water softening system. Inside the water softening system resin tank is a
bed made up of thousands of tiny, plastic resin beads. As hard water passes through the bed, each bead attracts
and holds the hard minerals. This is called ion-exchanging. It is much like a magnet attracting and holding
metals. Water without hard minerals (soft water) flows from the water softening system and to the house pipes.
After a period of time, the resin beads become coated with hard minerals and they have to be cleaned. This
cleaning is called regeneration, or recharge. Regeneration is started at 2:00 AM (factory setting) by the water
softening system control, and consists of five stages or cycles. These are FILL, BRINING, BRINE RINSE, BACKWASH
and FAST RINSE.
Automatic Hard Water Bypass During Regeneration
For emergency needs, hard water is available to the
home during the regeneration cycles.
However, you should avoid using HOT water because
the water heater will fill with the hard water.
Fill
Salt dissolved in water is called brine. Brine is needed to clean the hard minerals from resin beads.
To make the brine, water flows into the salt storage area during the fill stage.
Brining
During brining, brine travels from the salt storage area into the resin tank. Brine is the cleaning agent needed
to remove hard minerals from the resin beads. The hard minerals and brine are discharged to the drain.
The nozzle and venturi create a suction to move the brine, maintaining a very slow rate to get the best resin
cleaning with the least salt.
Brine Rinse
After a pre-measured amount of brine is used, the brine valve closes. Water continues to flow in the same
path as during brining, except for the discontinued brine flow. Hard minerals and brine flush from the resin
tank to the drain.
Backwash
During backwash, water travels up through the resin tank at a fast flow rate, flushing accumulated iron, dirt,
and sediments from the resin bed and to drain.
Fast Rinse
Backwash is followed by a fast flow of water down through the resin tank. The fast flow flushes brine from the
bottom of tank, and packs the resin bed.
After fast rinse, the water softening system returns to soft water service.

Breaking a Salt Bridge
Sometimes, a hard crust or salt bridge forms in the salt storage area. It is usually caused by high humidity or
the wrong kind of salt. When the salt bridges, an empty space forms between the water and salt. Then salt will
not dissolve in the water to make brine.
If the brine tank is full of salt, it is hard to tell if you have a salt bridge. Salt is loose on top, but the bridge is
under it. The following is the best way to check for a salt bridge.
Salt should be loose all the way to the bottom of the tank. Take a broom handle or like tool, and carefully
push it down into the salt, working it up and down. If the tool strikes a hard object (be sure it’s not the bottom
or sides of the tank), it’s most likely a salt bridge. Carefully break the bridge with the tool. Do not pound on
the walls of the tank.
If the wrong kind of salt made the bridge, take it out. Then fill the tank with nugget or pellet salt only.
In humid areas, it is best to fill with less salt, more often.

About the water softener system.
Cleaning the Nozzle and Venturi Assembly
A clean nozzle and venturi is needed for the water softening system to work properly. This small unit makes the
suction to move brine from the salt storage area to the resin tank during regeneration. If it becomes plugged
with sand, dirt, etc., the water softening system will not work and you will get hard water.
To get to the nozzle and venturi, remove the water softening system top cover. Be sure the water softening
system is in service cycle (no water pressure at nozzle and venturi). Then, while holding the nozzle and venturi
housing with one hand, remove the cap. Lift out the screen support and screen, then the nozzle and venturi.
Wash and rinse the parts in warm water until clean. If needed, use a small brush to remove iron or dirt. Also
check and clean the gasket.
NOTE: Some models have a small flow plug located in the nozzle and venturi, and/or a small cone shaped
screen in the housing. Be sure to check and clean these parts, if your model is so equipped.
Carefully replace all parts in the correct order. Lightly lubricate the o-ring seal with clean silicone grease or
petroleum jelly and place in position. Install and tighten the cap, by hand only. Do not over-tighten the cap.

Normal Operation, Timer Display
During normal operation, the present time of day and AM or PM show in the control display
area. When the demand computer determines a regeneration is needed, RECHARGE TONIGHT
begins to flash in the display along with the present time. RECHARGE TONIGHT flashes until
the next regeneration start time, then changes to RECHARGE NOW, which flashes until the
regeneration is over. The display also shows the current cycle in the regeneration process.
When the valve is in transition between cycles, both indicators flash.
Feature: Optional Recharge Controls
Sometimes, a manually started regeneration (recharge) may be desired or needed.
Two examples:
■You have used more water than usual (house guests, extra washing, etc.) and you may run out
of soft water before the next regeneration.
■You did not refill the storage tank with salt before it was all gone.
Use one of the following features to start a regeneration immediately, or at the next preset
regeneration start time.
RECHARGE NOW
Press and hold the TOUCH or HOLD button until RECHARGE NOW starts to flash in the control
display area. The water softening system begins an immediate regeneration and, when over in
about two hours, you will have a new supply of soft water. Once started, you cannot cancel this
regeneration.
RECHARGE TONIGHT
RECHARGE NOW
TOUCH
or
HOLD
RECHARGE TONIGHT
Touch (do not hold) the TOUCH or HOLD button. RECHARGE TONIGHT flashes in the control
display area. A regeneration will occur at the next preset regeneration start time. If you decide
to cancel this regeneration, touch the same button once more.
Feature: Program Memory
If electrical power to the water softening system is interrupted, the control display is blank, but
the control keeps correct time for about 72 hours. When power is restored, you have to reset the
present time only if the display is flashing. All other settings are maintained and never require
resetting unless a change is desired.
If the time is flashing after a long power outage, the water softening system continues to work as
it should to provide you with soft water. However, regenerations may occur at the wrong time of
day until you reset the control to the correct time of day.

Service: Manually Advance Regeneration Check
This check verifies proper operation of the valve motor, brine tank fill, brine draw, regeneration
flow rates and other controller functions. First, make the initial checks and the manually
initiated electronic diagnostics.
NOTE: The face plate display must show a steady time (not flashing).
Press the TOUCH or HOLD button and hold for three seconds. RECHARGE NOW begins to flash

as the water softening system enters the fill cycle of regeneration. Remove the brinewell
cover and, using a flashlight, observe fill water entering the brine tank.
If water does not enter the tank, look for an obstructed nozzle, venturi, fill flow plug, brine
tubing, or brine valve riser pipe.
After observing fill, press the TOUCH or HOLD button to move the water softening system into
2 brining. A slow flow of water to the drain will begin. Verify brine draw from the brine tank by
shining a flashlight into the brinewell and observing a noticeable drop in the liquid level.
NOTE: Be sure a salt bridge is not preventing salt contact with water.
If the water softening system does not draw brine, check:
■nozzle and/or venturi dirty or defective.
■nozzle and venturi not seated properly on gasket.
■restricted drain (check drain fitting and hose).
■defective nozzle and venturi seal.
■other inner valve defect (rotor seal, rotor & disc, wave washer, etc.).
NOTE: If water system pressure is low, an elevated drain hose may cause back pressure, stopping
brine draw.
Again, press the TOUCH or HOLD button to move the softener into backwash. Look for a fast
3 flow of water from the drain hose.
A slow flow indicates a plugged top distributor, backwash flow plug, or drain hose.
Press TOUCH or HOLD to move the water softening system into fast rinse. Again look for a fast
4 drain flow. Allow the water softening system to rinse for a few minutes to flush out any brine
that may remain in the resin tank from the brining cycle test.
To return the water softening system to service, press TOUCH or HOLD.

About the water softener system.
Service: Regeneration and Heavy Duty Backwash
NOTE: Each of the following functions has a factory set default value. The defaults are:
Regeneration start time –2:00AM; Maximum days between regenerations –0 (display shows dY–);
Heavy duty backwash –OFF. The defaults are suitable for most installations. However, depending
on water supply quality, household peak water use hours, etc., adjustment is available to meet
specific needs. To make a change, read and do the following.
Regeneration (Start) Time: At the 2:00 AM regeneration start time, the water softening system
begins regeneration at that time, ending at about 4:00 AM. This is a good time in most
households because water is not in use (see Automatic Hard Water Bypass During Regeneration
section). If a different time would be better for your needs, do steps 1, 2, 3, 5, 7, 8 and 9 below
to change the starting hour.
Maximum Days Between Regeneration: The default setting (dY–) allows the timer to control
regeneration frequency based on water usage readings from the water meter. It provides the
most economical operation. You can set a maximum time (in days) between regenerations.
For example, no more than three days will pass without a regeneration occurring if you set
dY 3 in the display. A 1 to 7 day setting is available. To make a change from the default setting,
do steps 1, 2, 3, 5, 7, 8 and 9 below.
Heavy Duty Backwash: When set to ON, the backwash cycle of regeneration will be 10 minutes
long instead of the normal seven minute length. This is beneficial on some water supplies
high in iron or sediment content. To conserve water, on clean supplies, be sure the default
setting OFF shows. To change this setting, do steps 1, 2, 3, 5, 7, 8 and 9 below.
Auto Regeneration When Capacity is Low: The softener will regenerate at the regeneration time
only. Although the control has a look-forward feature which anticipates normal demand, an
unusually high usage may result in a loss of softening capacity. Turning the feature ON will cause
the softener to go into a regeneration cycle when 97% of the softening capacity has been used.
To change settings do steps 1, 3, 5, 7, 8 and 9.

Care and cleaning of the water softening system.
Checking the Salt Storage Level and Refilling
Brine (salt dissolved in water) is needed for each and every regeneration. The water for making brine is
metered into the salt storage area by the water softening system valve and control. However, you must keep
the tank supplied with salt.
When to refill with salt: Check the salt level a few weeks after you install the water softening system and every
week after that. Refill when the brine tank is from 1/3 to 1/2 full. Never allow the water softening system to
use all the salt before you refill it. Without salt, you will soon have hard water.
Use clean water softening salts only, at least 99.5% pure. NUGGET, PELLET or coarse SOLAR salts are
recommended. Do not use rock, block, granulated or ice cream making salts. They contain dirt and sediments,
or mush and cake, and will create maintenance problems.
CAUTION: Water softening salt with iron removing additives: Some salts may have an additive to help the
water softening system handle iron in the water supply. Although this additive may help to keep the water
softening system resin clean, it may also release corrosive fumes that weaken and shorten the life of some
water softening system parts. GE recommends using only Diamond Crystal® Red•Out ® brand salt.
Cleaning Iron Out of the Water Softening System
Your water softening system takes hardness minerals (calcium and magnesium) out of the water. Also, it can
control some (see Specification Guidelines section) “clear water” iron. With clear water iron, water from a faucet
is clear when first put into a glass. After 15 to 30 minutes, the water begins to cloud or turn rust colored.
A water softening system will not remove any iron that makes the water cloudy or rusty as it comes from the
faucet (called red water iron). To take red water iron out of water, or over the maximum of clear water iron,
an iron filter or other equipment is needed.
GE recommends using only Diamond Crystal® Red•Out® brand salts with Iron Fighter® additive to help keep
the resin bed clean of clear iron. If your water supply has clear water iron, periodic resin bed cleaning is
needed. GE recommends using Super Iron Out® brand resin bed cleaner to thoroughly clean your resin bed
if your iron content is high. Clean the bed at least every six months, or more often if iron appears in the soft
water between cleanings.
IMPORTANT: It is important to mix the resin bed cleaner with water (following the manufacturer’s instructions),
pour it into the brine well (see page 6) and regenerate the softener immediately. Do not pour the resin bed
cleaner in with the salt, as it will not be as effective in cleaning the resin, and can cause damage to the softener
if it is left in the brine tank for an extended period due to the corrosive gases that are formed.

Troubleshooting Tips
Save time and money! Review the chart on this
page first and you may not need to call for service.
NO SOFT WATER – Most Common Problems:
Check the following before calling for service
•
•
•
Salt in softener...at least 1/3 full.
By pass valve in “Service” position. Knob should be in the OUT position.
Check hardness setting in control. Verify hardness of supply water. Water
hardness can vary throughout the year (see Programming the Control section).
•
Salt Bridge, water not in contact with salt (see Breaking a Salt Bridge section).
Problem
No soft water
Possible Causes
What To Do
Faucet or fixture where sample was
taken not plumbed to soft water.
NOTE: Be sure sample is from a faucet
that does not mix soft and hard water.
For example, a single lever kitchen faucet,
if the cold side is plumbed to hard water
•
To conserve salt, the installer may have isolated some fixtures
(outside faucets, toilets, etc.) from soft water. From the outlet
of the water softening system, trace the water flow path,
in house plumbing. If soft water is not directed to a faucet or
fixture where wanted, consult a plumber.
No salt in the brine tank or
salt bridged
•Check for a salt bridge or, if the tank is empty, refill with
recommended salt. Press (for 3 seconds) the TOUCH or HOLD
button to start an immediate regeneration and restore
soft water supply.
Transformer unplugged at wall outlet
or power cable to softener not
connected. Fuse blown or circuit

•
Any restriction in this drain hose may prevent proper operation
of the nozzle and venturi and reduce or prevent brine draw
during regenerations.
Nozzle and venturi dirty, incorrectly
assembled or damaged
•Refer to Cleaning the Nozzle and Venturi Assembly instructions.
With water pressure to the water softening system off, take the
nozzle assembly apart. Inspect, clean and replace as needed.
Any foreign particle(s), scratches, nicks, etc., in the passages
can prevent operation. Be sure holes in the gasket are centered
over holes in the housing.
