Frigidaire dishwasher flashing lights

We have a Frigidaire Gallery Dishwasher 8 years old. A year or so ago I had an incident where all the lights wash, add dish, rinse, dry, clean etc were flashing and nothing would make them stop. I looked online and found a series of buttons to push and it stopped. Of course I can’t find it again or where I wrote it down.

Occasionally when the cycle is done I will find the dishes clean and all the lights flashing, but pushing cancel makes it stop.

Well it happened again, but this time, cancel has not fixed the problem. I tried what I remember of the buttons, but that didn’t work. I threw the circuit breaker and waited 10 minutes. When we turned the breaker back on it now flashes PF (power failure in the timer window) and the hi temp wash and the no heat dry are blinking. And cancel does nothing.

Any ideas what the problem is or how I determine what the problem is?
thanks

Hi,

You can find the service manual for that dishwasher at one of the links below.

I can see a manual at the first site, but nothing in it seems to be my problem. The second site all I get is an error.

Anybody have any ideas? I am really tired of handwashing…
