Question about Dishwashers
Flashing PF = power failure. The power source and connections need to be inspected for bening loose or hot. This would be at the wall connection and in the bottom of the dishwasher. If the supply power source is good all the way to the dishwaher and to the dishwasher control.. suspect corrosion in the control area as the source of the problem. When corrosion gets on an electronic board it starts acting like a conductor for the low voltages produced by the PDB transformer which starts causing all kinds of weird symptoms. If the PCB can be cleaned carefully you can maybe get 6 months to a year out of a PCB that has / had corrosion problems. My 40 years experience is that only one in 5 can be salvaged back into service. Additionally those that are placed bacm in service eventually have other problems.
If you have a loose plug, wires, outlet or power cord... your in luck.

Hi dan76n - Typically PF appears in the display when the dishwasher is first installed, or when power has been interrupted. HI-TEMP WASH, SANITIZE and START/CANCEL backlighting will also flash. To clear, touch START/CANCEL pad. If it proves to be ineffective, once again try resetting the dishwasher by unplugging it or flipping the household circuit breaker off. Wait approximately ten minutes, restart unit and select a cycle. If the problem continues, the dishwasher could possibly be experiencing a wiring failure or faulty board. At this point I will highly recommend connecting with a certified technician for a further diagnosis and to accurately assist with the repair(s).

Hello babe_dog01 - PF typically appears in window when dishwasher is first installed, or when power has been interrupted. HI-TEMP WASH, SANITIZE and START/CANCEL backlighting will also flash. To clear, touch START/CANCEL pad or resetting the unit by unplugging it or flipping the household circuit breaker off. Wait approximately ten minutes. Since you have already done so and it was ineffective contact a professional to move forward accurately. Dishwasher could possibly be experiencing a communication error, wiring failure or faulty control board.
