Special Feature

Soil Settler

This model is equipped with a soil settler system. The inlet to the soil settler funnel is located to the

right and just behind the lower spray arm assembly. (Fig. 1-1)

Fig. 1-1

Since this inlet is located in an area that is relatively free of water turbulence, food particles washed

from the dishes can collect in this area and fall through the funnel and accumulate in the collector. (Fig.

1-2) Food particles continue to collect as long as the dishwasher is in the Wash mode.

COLLECTOR

PUMP INLET

HOSE

Fig. 1-2

When the Wash cycle is finished, the dishwasher will reverse the direction of the motor and enter the

Drain mode. Water is pumped into the port at the bottom of the soil collector during the Drain cycle

causing the ball in the collector to rise against the opening in the bottom of the funnel. Water flows

through and out of the collector through the top port and into the drain line. (Fig. 1-3) Food particles

collected during the Wash cycle are carried out with the drain water. When the Drain cycle ends and

the pump stops running, the ball settles to the bottom of the collector.

Fig. 2-1

POWER CLEAN FILTER Pump and Motor Operation

1. Once the tub has filled with hot water the motor begins to rotate forcing the water up through the

pump chamber and out through the spray arms. Two spray jets on the underside of the lower spray

arm direct water down onto the fine mesh screen of the pump housing to clear soils that may

collect there during the wash cycle. (Fig. 2-2)

2. As water and soils return to the lower pump area, the chopper blade grinds the particles into

smaller sizes that then pass through the perforated plate into the upper chamber of the pump. The

pump impeller causes the soil ladened water to be lifted and moved to the outer edges of the pump

chamber where they are forced into the separator. Clean water is then forced up through the spray

arms and fine mesh screen. (Fig. 2-3)

3. When the drain cycle begins, the drive motor changes direction. This relieves the pressure on the

two check balls, opening the drain system.

4. Water is pumped from the tub carrying soils from the separator into the drain sump of the pump.

(Fig. 2-4)

5. Soiled water is pumped out of the dishwasher through the check valve and drain hose. (Fig. 2-4)

CYCLE TIMING CHART NOTES

Note 1:

Pre-Wash Sense Interval

“sani rinse” has been selected, the target thermal hold temperature for the

“sani rinse” option must be satisfied and maintained. If this condition is not

satisfied (because the final rinse thermal hold default time elapsed or power to

the dishwasher was lost at any time during the remainder of the cycle that

follows due to a door opening or AC line failure) then the sani complete indica-

tor will flash on and off at the end of the cycle. Opening the door or pressing

any key will turn the indicator off in either case.

Pressure switch contact closure at any time during this interval causes the

cycle to jump to interval 37. Immediately. For the normal cycle, the heater is

“off” during this interval. For the heavy and pots-n-pans cycles the heater is

“on” during this interval. The power scour option changes this interval to a 16

minute heated wash interval for all 3 cycles (normal, heavy and pots-n-pans).

If the water temperature reaches 140ºF or the thermostat closes. The heater

is turned “off”. Time continues to elapse and all other output states remain the

same until the prescribed interval time has elapsed.

Note 12: Motor Drain Phase Winding

This output is only “on” when the motor is starting in the wash mode. When

the control has determined that the motor has started, the wash phase wind-

ing will be turned “off”.

Note 2:

Pre-Wash Thermal Hold

This thermal hold is only executed during the heavy and pots-n-pans cycles.

The thermal hold setpoint is 140ºF or thermostat contact closure and the de-

fault time is 25 minutes.

Note 13: Motor Drain Phase Winding

This output is only “on” when the motor is starting in the drain mode. When the

control has determined that the motor has started. The drain phase winding

will be turned “off”.

Pressure switch contact closure at any time during this interval causes the

cycle to jump to interval 37. Immediately.

Note 3:

Pre-Rinse Sense Interval

Note 14: Diagnostic Sensor Input Test

Pressure switch contact closure at any time during this interval causes the

cycle to jump to interval 31. Immediately. For the normal cycle, the heater is

“off” during this interval. For the heavy and pots-n-pans cycles the heater is

“on” during this interval. The power scour option changes this interval to a

heated wash interval for the normal cycle. If the water temperature reaches

140ºF or the thermostat closes. The heater is turned “off”. Time continues to

elapse and all output states remain the same until the prescribed interval time

has elapsed.

The soil sense pressure switch input is active during this interval. Pressure

switch contact closure at any time during this interval causes the cycle to jump

to the next interval. Immediately.

Note 15: Diagnostic Thermal Hold

The default status for this thermal hold is “on”. The thermal hold set point is

140ºF or thermostat contact closure and the default time is 60 minutes. After

60 minutes, the thermal hold is terminated and normal cycle timing resumes.

The diagnostic test cycle advance function can also be used to terminate this

thermal hold.

Note 4:

Pre-Rinse Thermal Hold

This thermal hold is only executed during the heavy and pots-n-pans cycles

and only occurs if the pressure switch trips during the sense or thermal hold

intervals of the pre-wash the thermal hold setpoint is 140ºF or thermostat con-

tact closure and the default time is 20 minutes. Pressure switch contact clo-

sure at any time during this interval causes the cycle to jump to interval 31.

Immediately.

Note 16: Cycle Complete

A clean indicator will be on at the end of this cycle. Opening the door or

pressing any key will turn the indicator off.

Note 17: Diagnostics Cycle -- Thermostat/Thermistor Indicator

The “clean” LED will turn on during the display test at the beginning of the

cycle (interval 11) and again at the conclusion of the cycle (interval 2) regard-

less of what it detects on the thermistor input. The “clean” LED will be on in

intervals 1 through 8 of the cycle whenever an “open” (resistance greater than

200K OHMS. +/- 50K OHMS) is detected on the thermistor input by the

control. Consequently, if a normally open operating thermostat were to be

installed on the thermistor input, the “clean” LED would be on throughout the

cycle until the thermostat tripped (e.g., during the thermal hold); With a ther-

mistor installed, the clean LED would only be on in intervals 10 and 0. Be-

cause the thermistor always has a resistance of between 50 K-OHMS and 8

K-OHMS under normal operating conditions.

Note 5:

Main Wash Thermal Hold

This thermal hold is automatic for the pots-n-pans and heavy cycles (set point

= 140ºF). For the normal cycle. This thermal hold is invoked by selecting the

power scour or high temp wash options (Set Point = 140ºF) or as a result of

the pressure switch tripping during the pre-wash (Set Point = 130ºF). For the

low energy wash and quick wash cycles. This thermal hold is invoked by se-

lecting the high temp wash option (Set Point = 140ºF). In all cases, the default

time for this thermal hold is 20 minutes

Note 6:

Main Wash Recirculation Interval

The power scour option increases the length of this interval to 10:00 for the

pots-n-pans and heavy cycles.

Options

Note 7:

Final Rinse Thermal Hold

Water Heat:

This thermal hold is automatic for all cycles except the china wash and rinse

only cycles (Set Point = 140ºF). For the china wash cycle, this thermal hold

only occurs if the pressure switch trips during the pre-rinse (Set Point = 130ºF).

In all cases the default time is 25 minutes.

Forces a thermal hold to occur in the main wash regardless of soil level. The

set point for this thermal hold is 140ºF. This option is automatic with the pots-

n-pans and heavy cycles. It is not available on china wash or rinse only cycles.

Sani Rinse:

If the sani rinse option is selected, then the set point for this thermal hold

becomes 150ºF and the default time changes is 25 minutes.

Raises the setpoint temperature of the thermal hold in the final rinse to ap-

proximately 65ºC/150ºF. This option is not available with china wash, quick

wash & rinse only cycles. This option is only possible on models that use a

thermistor.

Note 8:

Air Dry

The default status for the dry period is heat dry “on”. Selecting the “air dry”

option causes the heater to be turned “off” during this interval.

Air Dry:

Opens the circuit to the heater element during the dry period of the cycle. This

option is not available on quick wash or rinse only cycles (which have no dry

period).

Note 9:

China Dry Interval

When the china wash cycle is selected, the heater will be turned off during this

interval.

Power Scour:

Note 10: Option LED’s

When a valid option is active, then the LED for the option will be “on”.

Inserts additional heated wash time into the pots-n-pans, heavy and normal

cycle pre-wash sequence (interval 39 becomes a 16 minute, thermostatically

controlled, heated wash). Turns the heater on in interval 33 of the normal

cycle pre-rinse, invokes a thermal hold in the main wash of the normal cycle

and extends interval 23 to 10 minutes in the pots-n-pans and heavy cycles.

This option is not available on low energy, china wash, quick wash or rinse

only cycles.

keys within 10 seconds:

illuminated whenever the control detects a resistance of greater than

approximately 45 K-OHMS on the thermistor/ thermostat circuit. This

feature is intended to help determine whether a thermostat or thermistor

is installed. A thermostat with normally open contacts would trigger the

clean LED (until the thermostat is tripped). Under normal operation, the

resistance of the thermistor is always less than 45 K-OHMS and would

not trigger the clean LED.

The diagnostics test cycle may be manually advanced to the next inter-

val by pressing the pots & pans key. To exit diagnostics, press cancel.

The wash and drain auxiliary windings are only “on” when the motor is

being started. When the control has determined that the motor has been

started satisfactorily, the auxiliary winding will be turned “off”.

The sales demo cycle consists of a single 6-minute wash interval which

starts at interval 1 and concludes at interval 0. To initiate the sales

demo cycle, press the following sequence of keys within 10 seconds:

Entering the key sequence high temp wash (or power scour), air dry,

high temp wash (or power scour), air dry, after a cycle has started, will

Other Control Features:

The diagnostics test cycle executes a soil sensing interval at interval 9

to test the soil sensing circuit. The sensing LED is illuminated through

out this sense interval.

Cancel/Drain:

Terminates current active cycle and clears cycle selections. Executes 2-minute

drain upon first selection if water is likely to be left in sump. Subsequent

selections toggle between 2-minute drains and going to standby.

If the soil sensing pressure switch is tripped at any time during this sense

interval, the control will immediately terminate the sense interval and

proceed with the remainder of the diagnostics cycle.

Control Lock:

The control lock LED is illuminated and all keys of the keyboard are disabled

whenever the control lock feature is invoked by the customer. The control

lock feature (and LED) can be turned on or off by the customer at any time by

holding down the air dry option key for 4 seconds.

If the time limit for this sense interval elapses without detecting soil, the

control simply proceeds with the remainder of the diagnostics cycle.

The diagnostics cycle suspends cycle timing and executes a thermal

hold at interval 7. The thermal hold interval is terminated and cycle

timing resumes when the water is heated to the desired set point tem-

perature (60ºC/140ºF). The maximum default time limit elapses (1 hour),

or the cycle is manually advanced to the next interval by pressing the

pots & pans key. The water heating LED is illuminated during the ther-

mal hold.

Delay Start:

Allows the customer to delay the start of a cycle by up to 6 hours. Each press

of the delay key increases the delay time selection by two hours. The selected

delay period will begin clocking down upon selecting the cycle key. The cycle

selected will begin automatically upon completing the delay period.

Error Messages:

The clean LED is illuminated at the end of both the diagnostics test cycle

and the sales demo cycle. The clean LED can be extinguished by open-

ing the door or pressing any key.

Stuck Key:

If the control detects that a key is stuck in the depressed position, dishwasher

operation will be suspended and the control will flash the LED associated with

that key until the condition is corrected. If a key without an LED is stuck or

multiple keys are stuck, the control will flash the lock-out LED.

POWER CLEAN FILTER Pump and Motor Operation

1. Once the tub has filled with hot water the motor begins to rotate forcing the water up through the pump

chamber and out through the spray arms. Two spray jets on the underside of the lower spray arm direct water

down onto the fine mesh screen of the pump housing to clear soils that may collect there during the wash

cycle.(Fig. 3-1)

2. As water and soils return to the lower pump area, the chopper blade grinds the particles into smaller sizes

that then pass through the perforated plate into the upper chamber of the pump. The pump impeller causes

the soil ladened water to be lifted and moved to the outer edges of the pump chamber where they are forced

into the separator. Clean water is then forced up through the spray arms and fine mesh screen. (Fig. 3-1)

3. When the drain cycle begins, the drive motor changes direction. This relieves the pressure on the two check

balls, opening the drain system.

4. Water is pumped from the tub carrying soils from the separator into the drain sump of the pump. (Fig. 3-2)

5. Soiled water is pumped out of the dishwasher through the check valve and drain hose. (Fig. 3-3)

Servicing the Soil Sensing System

The Soil Sensing System consists of a pressure sensitive switch connected to the dishwasher pump

base. (Fig. 3-8) The system detects excessive amounts of food soils during the sensing portion of the

wash cycle and signals the electronic control board to either terminate the wash cycle and initiate

drain to flush soils from the system or skip certain parts of the heavy soil cycle.

The pressure switch is connected to the pump base through a plastic hose. The pressure switch is

secured to the bottom of the dishwasher tub by two (2) Hex- head screws.
