Jet Tech Systems Recent Questions, Troubleshooting Help & Support

Check the inlet screen to the water circulating pump and the water heater element for lime buildup. I've seen a heater element that had a 1/4" thick layer of lime encasing it. The inlet also had some lime and other debris clogging the screen. After carefully chipping away as much as was practical and running lime remover (such as CLR) through the machine, it heated the water much more quickly and had an effective spray. To prevent a recurrence of this problem, make sure you have a functional water softener ahead of the water heater feeding the machine.

Go to PARTSTOWN.COM at the top of the page pick the manufacturer, model and document type. hit the magnifying glass and it will apper if they have it.

Be sure you don't have "economy mode" turned on.

Ready light is there to tell you the thermostats have cycled off, rinse temp first and then wash temp after. if the wash temperature is low (below 160F) then we need to look at either the thermostat for wash or the heather is bad. if bot the temperatures are ok then it is just the light that is bad. If the rinse temperature shows 205F on analogue thermometer, a secondary reading is necessary with an external thermometer on the booster it self. These analogs thermometers are not so accurate.

a plug can be warm. if it is hot to the touch, stop using it and have the machine checked and the receptacle check by a qualified technician.

for models equipped with a drain pump; verify that the pump is not clogged. if it hums during the fill cycle or rinse cycle then something is lodged inside. If it doesn't then it needs to be replaced. for models without the drain pump; something is interfering with the water flow. when the stand pipe is removed, the tank should empty in about one minute.

Most Jet-Tech dishwashers has one adjustable rinse thermostat and one fixed wash thermostat. The wash thermostat can be substituted with an adjustable thermostat. Location depends on the model. F-18 are located on top. F-22 are located under next to the wash tank. Search by part number or description

If water keeps running even if the unit is unplugged than the water solenoid valve has become defective. if the water stops when power is off than there is a problem with either the timer or the fill switch. My bet is on the timer. Always be careful when opening the top cover. you will be exposing wires. power must be turned off at the breaker or the unit unplugged.

On the F-14, the booster thermostat must be satisfied. The rinse thermostat must work properly and or the rinse heater. follow the diagram. This kind of troubleshooting is done by qualified technician. Remember to unplug the unit before opening the panels. It could be just a burnt wire on the rinse booster heater connection. .

It depends on how old is the machine. the more recent unit (5 years) used door guide (green) #16468. Search by part number or description

The F-22 wash tank heater is controlled by a thermostat that opens or close a relay located in the control panel on the right. the thermostat is located inside the machine next to the wash tank. the thermostat is fixed position and can not be adjusted. the temperature should be 170F max. The thermostat has a bulb attached by a wire. this wire is actually a tube and the bulb is filled with an oil that expends when heated. the bulb is inserted in a cavity in from of the wash tank. You can access this by removing the front panel. If the bulb is not in the cavity, it will produce alot of heat. if the "wire" is broken or just simply the thermostat has become defective than it should be replaced.

Try searching for commercial liquid detergent. Companies like Ecolab will sell it.

The detergent system on the Jet-Tech machine are all very similar. Near the solenoid valve under the machine, beside the drain connection, there are two wires, one red and one blue. Those wire will run the detergent pump when the machine calls for water. Two tube are attached to the pump. when looking at the pump from the front or clear plastic can be seen, the tube on the left (arrow going up) is connected to the container with the detergent. the tube on the right (arrow down) is connected to the back of the unit to inject the detergent into the tank. Some precaution should be taken to assure that the connections are tight and not leaking. if the tube shows signs of crystals inside, it should be replaced as the detergent as crystallized within.

Verify the contactor for working condition. maybe burned wires or bad contactor. if it is good then the rinse thermostat or, less likely, the booster element.
