GE Dishwasher PF Error Code — What it Means & How to Fix It
What the PF code means
The PF code on a GE dishwasher stands for Power Failure (sometimes shown as Power Fault). It indicates the dishwasher detected an interruption or anomaly in its electrical supply during a cycle. This error usually appears after a brief loss of household power, a tripped breaker, or a transient electrical surge. While PF most often points to a temporary interruption that can be cleared by restarting the appliance, recurring PFs can signal wiring issues, a failing control board, or other components that require attention.
Common user impacts include aborted cycles, unheated wash or dry phases, lights or display going blank, and longer drying or cleaning times because the dishwasher may not complete its programmed sequence. Repeated power interruptions or persistent PF errors can lead to incomplete washes, increased energy use, and in rare cases, electrical hazards if caused by damaged wiring or failed electronics.
Common causes
- Temporary household power outage or brownout
- Tripped circuit breaker or blown fuse on the dishwasher circuit
- Loose or damaged wiring connections at the junction box or terminal block
- Faulty electronic control board (main PCB) or power supply section
- Unstable incoming voltage or frequent electrical surges
- Touchpad/console glitches that fail to register a reset
- Door latch not making proper contact causing the control to misinterpret power state
- External surge protector or GFCI/AFCI device tripping unexpectedly
Troubleshooting steps
- Reset power: Turn off the dishwasher at the circuit breaker for 1–2 minutes, then switch it back on to clear the PF code. Many PF events are cleared this way.
- Check household power: Verify other appliances and lights on the same circuit are working. If multiple devices are affected, troubleshoot home power or contact an electrician.
- Inspect the breaker/fuse: Ensure the circuit breaker hasn’t tripped and the fuse (if used) is intact. Reset the breaker and test the dishwasher on a full cycle.
- Examine the door latch: Make sure the door closes fully and the latch engages. A loose latch can cause intermittent control behavior that mimics a PF condition.
- Look for loose wiring: With power off at the breaker, remove the access panel and inspect the terminal block and wiring harness for loose or burnt connections. Tighten any loose screws and repair damaged wires before restoring power.
- Test the control console: If the display is unresponsive after power is restored, try a control lock/unlock or perform the manufacturer’s reset sequence (consult the model manual).
- Watch for surges: If your area has frequent voltage spikes, consider using a whole-home surge protector or dedicated surge protection for the dishwasher.
- Run a diagnostic cycle: On many GE models you can
