GE dishwasher — Error Code PF
The internal control system has identified a loss of power or a fluctuation in voltage.
What it means
The PF alert on your GE dishwasher stands for Power Failure. This notification occurs when the main electronic control board senses a complete shutdown or a dip in incoming AC power during a wash cycle, or after power returns following an electrical interruption. This is a status notification rather than a direct component breakdown. The unit stops its operation to prevent potential issues like flooding or erratic cycling caused by interrupted fill or drain phases. While a neighborhood power flicker—common during stormy weather in the Pacific Northwest—is the usual culprit, seeing this code repeatedly suggests an internal electrical problem. This could involve loose wire nuts within the junction box, a failing door latch switch causing intermittent circuit breaks, or an aging power supply on the main control board.
Likely Causes
- 1 House Power Outage or SurgeGeneral grid interruptions, a tripped circuit breaker in your electrical panel, or voltage fluctuations will cause the board to trigger a PF warning.
- 2 Loose Junction Box WiringVibrations from standard operation can loosen the wire nuts securing your home's Romex to the dishwasher, leading to arcing and intermittent power drops.
- 3 Faulty Door Latch SwitchA worn-out microswitch inside the door latch assembly can cause the circuit to open if the door shifts slightly during a high-pressure wash cycle.
- 4 Failing Main Control BoardInternal components like capacitors or relays on the control board may be degrading, causing the processor to restart and display a false PF error.
How to clear / reset
To clear the PF code, press the Start/Reset or Cancel button on your interface. Allow the dishwasher about 2 minutes to perform a short drain cycle and reset the board. If the error remains or the buttons are unresponsive, perform a hard reset by shutting off the circuit breaker for 5 minutes before turning it back on. If the PF code reappears immediately or pops up randomly without any household power issues, a deeper electrical inspection is required.
Common replacement parts
When to call a pro
Contact our team if the PF message persists after you have reset the breaker and confirmed your home's power is stable. Diagnosing these power issues requires a multimeter to check for voltage under load at the junction box, verify continuity in the door switches, and inspect the integrity of the main control board. Working with 120V AC systems carries risks of fire or electrical shock. A-Fix Service offers a $90 diagnostic fee, which is waived if you proceed with the repair, and we include a 1-year warranty on all parts and labor.
FAQs
How much does it cost to fix a GE dishwasher PF code?
Simple repairs, such as tightening loose junction box wiring, typically range from $120 to $150 including labor. If you require a new main control board, costs usually fall between $250 and $400 depending on the specific model.
Can I fix the PF error myself?
You can resolve the code if it stems from a brief power outage. However, persistent errors require inspecting junction box wiring, which should only be attempted if you have the breaker off and are experienced with handling line voltage.
Will the PF code clear itself?
No, the dishwasher requires you to manually acknowledge the power failure. You must either press the Start/Reset button or cycle the breaker to clear the display.
How long does it take to repair?
Securing junction box connections or replacing a door latch usually takes 30-45 minutes. Swapping out a main control board generally takes less than an hour once the correct part is sourced.
Is it safe to keep using the dishwasher if the PF code keeps flashing?
No. If the PF code is caused by loose wiring in the junction box, continuing to operate the unit can lead to arcing and melted wires, creating a significant fire risk.
