Water Level System  
1 888 275 4538 - 611  
514 737 9701 - 611  
The dishwasher water level is control by a pressure switch or  
pressostat. A cup (grey plastic cylinder, #10528) located at the back of  
the unit will keep an air pocket which will be pressurized as the water  
level increases. The air pressure (approximately 2 inch water column)  
activates a switch through a rubber tube that connects from the air trap  
to the pressostat.  
During the fill cycle, the water solenoid gets its signal from the  
pressostat. When the pressostat is satisfied, it cuts the signal to the  
solenoid valve and sends power to the thermostats and the timer  
When trouble shooting this system, all components must be  
considered.  
Beginning with the pressostat which is adjustable.  
Making sure the connection to the tube is air tight.  
The tube may have an invisible crack which allows air to escape.  
The air trap may be broken or the threads may have a crack also.

Fill System & Rinse System  
The dishwasher fill and rinse systems is practically the same system as they both used the same circuit.  
The only difference is what is sending the signal to the water solenoid valve.  
During the fill cycle, the water solenoid gets its signal from the pressostat. When the pressostat is  
satisfied, it cuts the signal to the solenoid valve and sends power to the thermostats and the timer.  
During the Rinse cycle, the water solenoid valve is getting its signal from the timer. When the time has  
completed the rinse cycle than the solenoid is de-energized.  
Because the detergent pump and the drain pump (if so equipped) are connected in parallel with the  
water solenoid valve, they will all work at the same time. Why are they connected this way? Simple,  
the detergent pump is connected this to inject detergent whenever new water comes into the  
dishwasher. The detergent does not mix with the rinse system so it does not contaminate the rinsing  
process with detergent.  
The drain pump will  
work whenever the  
water solenoid  
opens and this is to  
avoid overflow  
problem should the  
pressostat becomes  
defective and the  
unit get stuck in a  
fill cycle. Here it si  
important to keep in  
mind that this  
scenario will only  
work if the dynamic  
(flow) water  
pressure does not  
exceed 25 PSI and the unit is capable of totally draining  
within 1 minute. If any of those two factors exceeds the  
limits then you can have an overflow situation.  
The water solenoid valve will send water through the booster first and then water will travel to the  
spray-arms as shown in the diagram below. The solenoid valve will fail under specific condition. High  
pressure(>2.0 bar: >30 PSI) , high temperature(>60C:>140F), debris in water,  
continuous work.

TIMER SEQUENCE  
1- When the Start Cycle TC (20519) button is  
depressed. The small contactor relay is energized and  
closes contacts CR1 (20067) and CR2 (20067). This  
has two purposes. The first one is to energize both the  
timer motor and the indicator light LC (20042). The  
second purpose is for CR2 to bypass the Start Switch  
TC.

2- The timer motor is energized and starts to turn and  
closes the first contact M1 (20518) which will bypass  
the small relay contactor and keep the timer motor  
running during the entire cycle.  
3- As the timer cam continues to turn, the second  
switch M2 (20518) is closed and energizes the wash  
pump motor.  
4- After 150 seconds approximately, switch M2 opens  
and switch M3 (20518)closes to energize the solenoid  
valve (for rinsing), the drain pump and the detergent  
pump. This function lasts about 20 seconds and the  
circuit reverts to the beginning.

ELECTRICAL SEQUENCE  
As the unit is powered by the Power Switch (1), it energizes LL(2).  
The Pressure-switch PS energies the solenoid valve ELB (to fill the wash tank), the detergent pump  
PD and the drain pump DP.  
When the pressure-switch PS(20058) is satisfied, it energizes the Booster relay contactor  
BCB(20104) by the rinse thermostat TB(20596).

When the Start Cycle TC (6-20519) button is depressed. The small contactor relay (20067) is  
energized and closes contacts CR1 and CR2. This has two purposes. The first one is to energize both  
the timer motor and the indicator light LC (7). The second purpose is for CR2 to bypass the Start  
Switch TC.  
The timer motor MT is energized and starts to turn and closes the first contact M1 which will bypass  
the small relay contactor and keep the timer motor running during the entire cycle.

As the timer cam continues to turn, the second switch M2 is closed and energizes the wash pump  
motor MPL(40240).  
After 150 seconds approximately, switch M2 opens and switch M3 closes to energize the solenoid  
valve ELB (for rinsing), the drain pump DP and the detergent pump PD. This last about 20 seconds  
and the circuit reverts back to timer at rest..

CHEMICALS AND PUMP ADJUSTMENT  
Dishwashers require the use of a detergent and possibly a rinse additive. The detergent  
must be of commercial strength to work in the unit’s short cycle. The rinse additive will  
help the water to sheet on the glasses and plates, acting as a drying agent.  
The products are a Sodium Hydroxide for the detergent and a surfactant isopropanol for  
the rinse. Quantities will vary with water quality but as a guideline there should be 200  
ppm for the detergent and 50 ppm for the rinse-agent. Those products are available from  
any chemical company. Never use chlorinated product such as sanitizer and bleach.  
These products can damage the equipment.  
Should you run out of these products, you can use residential brand product as a  
temporary measure. Do NOT use soap that produces suds. Use those product that are  
sold for dishwashers. Good quality chemical product will improve the washing.  
Models 727, 737, F-16, F-16DP, F-18, F-18DP & F-20 are supplied with a factory installed  
liquid detergent pump to automatically dispense detergent into the wash tank chambers.  
Before accessing the bottom section of the dishwasher, make sure that the power was  
turned off at the source (breaker panel).  
The bottom panel can only be remove with a flat tool  
like a screw-driver. Insert the screw-driver in the gap  
between the front panel and the side panel. Pry open  
towards you. Do this on both side.  
The clear hoses connected to the pumps must be  
pulled out and fed through the bottom of the  
dishwasher. The containers can be either to the right  
or left of the dishwasher. Perforating the stainless  
panel is not recommended.

The quantity of liquid detergent can be increased  
(clockwise) or decreased (counter clockwise) by adjusting  
the screw on the peristaltic pump. The pump works during  
the fill cycle and rinse cycle.  
(Identified above as “Adjustment screw”)  
Don't forget to put the panel back on when finished.  
RINSE PUMP ADJUSTMENT AND PRIMING  
· The rinse pump is standard equipment on all JET-TECH machines and automatically injects  
rinse additive into the rinse water for the final rinse.  
· The rinse pump is located  
in the base of the machine  
near the booster tank. The  
front, lower panel (below the  
door) snaps off to access the  
rinse pump. Cut the cable  
tie, route the tube out from  
the base of the machine and  
drop the clear vinyl hose and  
filter into your rinse additive  
container. (Some models are  
supplied with a rinse additive  
bottle that fits inside the  
base of the machine)  
Adjustments should be made clockwise to reduce the amount of rinse additive and counter  
clockwise to increase the amount of rinse additive.  
· If air gets in the rinse hose or if the pump stops drawing additive from the container, the pump  
may need to be primed.  
To Prime (accelerate the injection of chemical) the pump, follow these steps;  
1) Turn OFF the machine, pull the overflow, and drain  
the wash tank. The wash tank must be empty has  
priming is done during the fill cycle.  
2) Get access to rinse-additive pump (see above  
instructions) Turn the adjusting screw on the rinse  
pump approximately 10 turns counter clockwise,  
allowing maximum travel for the piston. The screw  
may fall out but this is not a problem. Just remember  
how many turns you had made when the screw fell  
out.  
3) Turn the machine ON and count to 5, then turn the  
machine OFF and count to 5, do this several times,  
until the liquid is drawn up the tube to the rinse pump.  
Because the pump works when the water solenoid

opens, causing the water pressure to push the internal piston, you should be able to see the  
liquid travel the length of the tube.  
4) Once the liquid as reached the back of the pump, turn the adjusting screw on the rinse  
pump clockwise all the way in and counter-clockwise 3 full turns.  
The rinse-aid pump can pump up to 3cc of rinse-additive (drying agent). The liquid is injected  
directly in to the booster tank.  
DO NOT use sanitizer (chlorinated products, bleach) with this pump. It is not made to pump  
harsh chlorinated liquid. This will void warranty on the dishwasher.  
Know Your Application.  
When purchasing the detergent, it is important to specify what you want to wash. Most  
detergents sold on the market are good for regular soil (Non-greasy food on dishes and  
cups). Coffee and lipstick stains are usually very difficult to remove and pre-washing may be  
required. Greasy pans will involve a more specialize product. If an incorrect product is used,  
grease will accumulate inside the washing cabinet and cover everything.
