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.

FDB4315LFC2 runs then stops and flashes pf ?


Good Morning Friend,

I understand that your Frigidaire dishwasher, model# FDB4315LFC2, starts and then stops, and flashes a "PF" code when it stops. The "PF" code is stating that there has been a power failure. There could be a possibility that your dishwasher is losing power mid-cycle. I suggest checking your home's circuit breaker, the wiring to your dishwasher, and if you have a cut-off switch, checking that as well. I also suggest resetting your appliance, by shutting the power off at your home's circuit breaker, for 20-30 minutes. Restore power and start any cycle. If further troubleshooting is needed, I ask that you please let me know the error codes displayed on your appliance. Hope this is helpful.

-Best Regards-

Kenmore elite dishwasher model 630 Smart Wash light is flashing


You may want to try:
Press a series of four buttons in quick succession. Press "Heated Dry," "Normal Wash," "Heated Dry" and "Normal Wash" to instruct your Kenmore dishwasher to run a short diagnostic test.
Wait for two minutes while your Kenmore dishwasher runs its diagnostic test.
Press the "Cancel/Drain" button once your dishwasher has completed its diagnostic test. This should reset your dishwasher control panel.
Check to make sure that there's no standing water in the bottom of your dishwasher. Standing water in your dishwasher may indicate that your dishwasher has stopped mid-cycle. You will need to press the "Cancel/Drain" button before you can reset your dishwasher control panel.

Electrolux EX600 Dishwasher loosing power during wash cycle


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).

PF, high temp wash and air dry lights blinking. Reset main breaker but no help.


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.

How do I Cancel a wash cycle? I have no manual


The Reset button is the correct button to cancel the cycle, it takes up to a minute or so the drain. If the buttons are not responding, there could be a problem with the door closed switches.

My dishwasher runs for bour 10 minutes. Then stops, and flashes PF?


Mine does the same thing. I'm confident that the problem lies in the "computer" which is essentially the buttons for selecting the various wash cycles. That strip is basically a thick band with adhesive on the back by which it is glued to the top of the dishwasher door. There are wires connected to it. The wires run down into the door and connect to a terminal that is built into the door. The inside door panel must be removed to install a new button strip or "computer." Mine was replaced twice in the first year. Now it is three years old and needs to be replaced again. I'm going to look around on the net to see if I can find one.
