FIXED Dishwasher tripping circuit breaker Model PLDB998AC0

I have a Frigidaire PLDB998AC0 dishwasher which has been up until recently running perfectly. The other day i went to use it and there was no power to the front panel. Went downstairs and found it had tripped the breaker. Clicked it over and the machine was displaying the PF code on the screen with no other lights, pressed the cancel button and it didnt go away. I open the door with the handle, the power went off again and tripped the circuit breaker.

I was going to test the switch in the handle tonight, but wanted to see if anything else could be causing i.e control board or any other testable part while i have it in pieces.

Many thanks

Jason
