20 Most Recent Jet Tech Systems 24 in. 737 Free-standing Dishwasher Questions & Answers

The reason the temperature are going up is the heating system is defective. The thermostat on the booster (rinse) is not satisfied. First thing to verify is the contactor that is activated by the rinse thermostat. Often one of the wires on the contactor will burn.

YOur best bet is still the electrician.

However, I would get him to go through the electric diagrams contained in this website. Scroll down to the F-22 model. He will need to check if the model is single or 3 phase mains. It is likely the Earth connection has come loose.

Once you get him there he can also call Jet Tech support (see the phone no. on the website) explaining the problem. They are based in Canada but have a toll free support line.

I hope this helps and you can get back to operations soon. It must be a big inconvenience to your business not being able to get the dishes washed.

Please rate the solution if this helps.

Ouch.

Before you start changing all sort of parts, correct your problem with the wires. You may have to change most of them, depending on how bad the chemical burned tru them.

A good cleaning is required because that soap is going to continue chewing on those wires.

You're right about a short causing other component failure. But first repair those wires

The 737 model could run on even lower temperature (80F). Given time, the unit will heat up the water. the trick is to give it time.

That model is made for commercial use, not really for residential. It will not fully drain every cycles. The important thing to keep in mind is to empty the dishwasher (turn it off, pull the stand-pipe out, and drain) every night and left empty. When you want to use the unit, put the plug back in and turn it on, wait 20 to 30 minutes and it should be ready.

the heater in the unit is supposed to heat both the wash water and the rinse water.
if it is not, then you have a problem in a controller or an element.
how are you determining the temperature and are you waiting for the unit to signal ready before you test it?

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

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. .

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.

If the machine will fill on its own when it is empty then the rinse cam on the timer is defective

No idea as i would either make my own or go to general store in alicante and ask the nice man if he has anything that would do the job if the original parts were not available
