I have a duet GEW9250PW1 electric dryer, it is just past warrantee. The machine started blowing the circuit breaker and thus shutting down. When power is restored, the code is ?PF,? no help. Have attempted to monitor to the shutdown point and have observed no other codes. Have removed vent hose to physically feel flow, the flow seems to fluctuate slightly, and the heat seems to fluctuate, is not constant. Can you aid in a direction to determine real problem?
Thank you. Soft Touch
PS I hooked up another older dryer to the same circuit and the breaker stays on.

Re: code "PF" = N/A
-PF- means power failure, nothing else. Most likely the problem is not with the dryer. The circuit breaker became too weak for the dryer load. I beleive replacing the circuit breaker will solve the problem.
Take off the front lower panel and look for lint around the sensors that are on the top of the air duct that runs from the fan to the heat tunnel. Mine had an electrical arc between a sensor and the duct, which tripped the circuit breaker. You can see a small scorch on the duct if it has arced. The dryer still works once you flip the breaker back on, but on mine, it opened the loop on the dryness sensor so that no longer works. Only solution for me is to replace the whole circuit board. Hope this helps :)

Press and hold the "Start" button to restart the dryer cycle if the "PF" (power failure) error code appears. This code often appears when a cycle is interrupted before it completes. You may also check the breaker or household fuse, and ensure the machine has not come unplugged.
PF is a power failure error meaning electricity has been interrupted to the machine. Any electrical interruption to the machine such as a circuit breaker being reset or weather related power outage can cause a PF error code. Try resetting the appliance by disconnecting it from the outlet or switching off the circuit breaker for 20-30 minutes, then restore the power. If the reset doesn't work I suspect the control board has failed.
What you could do is get the service panel off the base of the machine. On the backside of it is the tech sheet which gives explanations of the codes given. You would thin it stands for Power failure and it might just be a faulty breaker. They recommend the washer have its own dedicated line without any other things on that line. Some codes require a ground fault interupter on the receptacle near any machine that uses water in case of flooding. That could be causing the PF.
Here are the source codes that pop up on the dryer with the "fix"
PF Power failure "PF" flashes to indicate that a power failure occurred while the dryer was running. Press HOLD TO START to continue the cycle, or press OFF/Pause to clear the display.
