GE Profile GFW850 Washer PF Error Code: Power Failure... | appliancefaults.com

Technical Background:

The "PF" error code on the GE GFW850 washer indicates a power failure event. The Main Control Unit (MCU) detects an interruption in the 120V AC power supply. The MCU monitors the incoming voltage and stores error codes in its memory. Loss of power during operation can corrupt the wash cycle programming and trigger the error.

Symptoms:

The GE Profile GFW850 washer displays a "PF" error code. The washer may have stopped mid-cycle, and the control panel might be unresponsive. The homeowner reports a recent power outage or flickering lights.

Possible Causes:

Sudden power outage during a wash cycle.
Loose wiring connection to the washer.
Faulty main control board (MCU).
Tripped breaker at the breaker panel.
Surge protector malfunction.

Solution:

1

Unplug the washer from the outlet.
2

Check the breaker panel for a tripped breaker. Reset if necessary.
3

Using a multimeter, verify 120V AC at the outlet.
4

Remove the rear access panel of the washer. You will need a 1/4-inch nut driver for this.
5

Inspect the wiring harness for loose or damaged connections, especially at the main control board.
6

Disconnect and reconnect the main control board connectors to ensure a good connection. Check the voltage input connector with a multimeter for correct voltage, typically 120V AC.
7

Plug the washer back in and run a test cycle.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed. High voltage is present when the appliance is connected to power.

Prevention:

Use a surge protector to protect the washer from power surges. Periodically check the outlet and wiring connections for tightness. Avoid overloading the circuit with other high-power appliances.

Expert Tip:

Enter the service mode by pressing and holding the Start/Pause and Temp buttons simultaneously for 3 seconds. This allows you to clear error codes and run diagnostic tests.

Frequently Asked Questions

•What is the procedure for clearing the PF error code from the washer's memory?

After addressing the power issue, you can try to clear the error code by unplugging the washer for 5 minutes to reset the control board. Alternatively, use the service mode to clear the error log.

•If the breaker is not tripped and the outlet is working, what is the next most likely cause of the PF error?

If the breaker and outlet are good, suspect a faulty main control board (MCU) or a loose connection within the washer's wiring harness. Carefully inspect all connections to the MCU.

•What voltage should I expect to see at the main control board?

You should see 120V AC at the input power connector to the main control board. Use a multimeter to verify this.
