Question about Microwave Ovens
If your Whirlpool dishwasher flashes F1, it denotes NTC error.
NTC = Negative Temperature Co-efficient.
Basically it's a temperature sensor also known as a feeler.
Common problem with Whirlpool machines.
If your machine is younger than 5 year old and the NTC is at fault it will be failing before going onto fill only.
It should pump and fill at the same time while the on board software runs it's diagnostics. Any part fails the diagnostics the machine aborts the program. Reverts to the rinse (or 1st program) symbol and flashes an error code on the start light.
Pour a kettle of boiling water into the sump of the dishwasher and try running it. Sometimes the NTC can be shocked into working, for a while.
Please leave me comment, if you need furthur assistance

Tips for a great answer:
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.

Thank you for your inquiry, Leanne!
From the information you have provided your Electrolux microwave is displaying an error code of "F1". I am showing that an "F1" error code is not valid. I would recommend resetting your microwave and you can do that by flipping the household circuit breaker off for at least ten minutes. If that does not correct your issue and you continue to experience an "F1" code please reconnect. -Matt
