My frigidaire dishwasher works intermittently. It'll completely stop mid -cycle, as if the power was shut off - then eventually indicate a power failure on the display. Then it wil work fine for a c

Based on the symptoms you described, it's likely that there is an issue with the heating element or thermostat in your Frigidaire dishwasher. Here are some troubleshooting steps you can try:

1. Check the heating element: The heating element is responsible for heating the water during the wash cycle and drying the dishes at the end of the cycle. If the element is faulty, the dishwasher may stop mid-cycle and display the flashing lights you described. Use a multimeter to test the continuity of the heating element. If there is no continuity, the heating element needs to be replaced.
2. Check the thermostat: The thermostat is a safety device that prevents the dishwasher from overheating. If the thermostat is faulty, it may shut off the heating element prematurely, causing the dishwasher to stop mid-cycle. Test the thermostat using a multimeter. If it's not functioning properly, it needs to be replaced.
3. Check the control board: If the heating element and thermostat are functioning properly, there may be an issue with the dishwasher's control board. A faulty control board can cause various issues, including the flashing lights you described. If this is the case, you may need to replace the control board.

If you're not comfortable performing these troubleshooting steps yourself, it's best to contact a qualified technician to diagnose and repair the issue.

PF code on Frigidaire dishwasher
Since the PF indicates a power failure, it has most likely lost electrical connection before the control board and this is the most likely place for this to occur. Frigidaire dishwasher (PLD4375RFC0) seems to complete wash cycle but often has power failure (PF) code during the dry cycle.

the latch must be fixed for it to work a broken latch will cause this problem Frigidaire Gallery dishwasher has the code PF Google Search

also we need to know what model it is to recommend a part

two things to look at : water level sensor ? seems I once had a machine that the water inlet valve never totally shut off and it overfilled basin this shut machine off on a spill sensor fault but took several minutes to do this , Also the door closed switch , seems they do get finicky as time goes on and even thought door stays closed the movement of machine opens the door switch up (not the door) this also takes several minutes to occur

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.

Good Morning AA1970,

I see that you are having trouble with your Frigidaire dishwasher, model# FFB240, continuing to run unless you shut it off. While I'm not familiar with this particular model number, I suggest that you give the appliance a hard reset. You will do this by shutting the power off at the circuit breaker for at least 20-30 minutes. After restoring power, run the cycle. If it is still continuing to run unless you shut it off, I suggest contacting a local authorized technician for further assistance.

Sounds like the timer module is going bad. Might be getting moisture on contacts. That would explain why it works one time and not the next.Just trying to help!

Hello - From what you are describing it appears that the unit is attempting to run the cycle, but the wash motor is not coming on. Either the wash motor has failed or there isn't any or isn't enough power supplied to the wash motor. I personally recommend contacting a service provider to accurately diagnosis the dishwasher and to assist with the repairs.

Try to reset unit to factory defaults. If necessary contact mfg for protocol to accomplish this

Shut the breaker to the dishwasher off for 2 hours then back on, this will give it a reset. Your problem was caused by a power spike

Hey Jim, if your model starts with 665 there was a service flash on this unit concerning your problem. SF-22-715. Dishwasher stops in mid cycle. The control board was redesigned to eliminate this problem. The service flash states that if only one indicator light is blinking it's usually a stuck or shorted keypad. I would check with Sears and see if you are covered under this service flash. Catriver...post back.
