Jenn-Air Dishwasher Repair

Appliance:
Jenn-Air Dishwasher

Problem:
Jenn-Air Dishwasher Stopped Before Completing the Cycle and Will Not Restart.

Dishwasher was turned on, but only ran through half of the cycle and stopped. Dishwasher was reset by shutting it off at the circuit breaker, but when it restarted it gave a "PF" code on the display.

Solution:
PF stands for power failure, so what the control board is saying is that the power turned off.

When dishwasher goes through a cycle and it gets to the rinse portion, it stops and heats up the water.

It doesn't necessarily stop the wash arms, but the advancing of the program will stop, and it will turn on the heating element in the tank and heat the water up to a predetermined temperature. Depending on your selection - sanitary wash or regular wash, normally it's around one hundred and fifty to (on some of the newer units) one hundred and seventy degrees. Once the machine hits the desired temperature, it will continue.

If there is a problem in the heating cycle, it will cause the dishwasher to sit there forever until it senses that it's time to move on. So, if your heating element has failed, this may have caused the problem.

Or, there is a small thermostat underneath the tank that senses when the tank temperature is properly heated and it alerts the control board to move on. There is a possibility that your control board has failed.

The other thing you can do to take care of your Jenn-Air dishwasher repair, is make sure that all the connections on the circuit board are correct and re-secure all the connections on it.

With dishwashers, one is dealing with moisture and, on occasion, moisture gets into the connections on the board and can cause a problem. Sometimes by jiggling the board a bit, one can get it to work.

If the jiggling does not help, the board needs to be replaced. The problem could be a small crack on the circuit board, which over time will work intermittently and unreliably.
