I have a Wascator tt500 with an F1 error on the display.

Error Code/Message - Oven - F1 Error Code - F1 E5

Control displaying F1 E5:

There may be a problem with the Oven Control, or the associated wiring.

Power unit down by turning off the circuit breaker(s) for one (1) minute.

Power unit up by turning on the circuit breaker(s).

Monitor the oven for one (1) minute to ensure the error code does not display again.

Verify oven operation.

There should be F1 on both displays. "If power fails to the bottom tub it will cause the top tub to go F1. Test heater plate." (from the service manual).
If there is F1 on both displays it could be a faulty flood switch or PCB.

Try google factory manual for the diagram.

First thing you can try is to unplug the dryer for fifteen minutes or so. If that still bring up the error code then it is your board inside your dryer.

f1 is the flood switch theres a moisture sensor on the bottom and leaves the pump nrunning

F1 Failed Thermistor Control Replace Electronic Range Control (ERC)
Good Luck and Please Rate Fixya!
