Haier Washer Error Code PF — Power Failure (Low Voltage)
What this means
Error code PF on Haier washers indicates the incoming voltage has dropped below approximately 93 volts AC, which is too low for the machine to operate safely. This can occur during a brownout, if the home's electrical circuit is overloaded, if the power cord is damaged, or if the outlet has a loose connection. The washer will stop mid-cycle to protect its electronic components from damage caused by undervoltage conditions.
Alternate codes: pF
Step-by-step fix
3 stepsCheck for a power outage or brownout
Look at other appliances and lights in your home. If lights are dim or flickering, you are experiencing a brownout. Wait for power to stabilize, then restart the washer.
During a brownout, unplug sensitive electronics (including the washer) to protect them from voltage spikes when power returns to normal.
Test the outlet voltage
Using a multimeter or voltage tester, measure the voltage at the wall outlet. A standard US outlet should read 110–125 volts AC. Below 100V indicates a wiring problem or overloaded circuit.
Do not share the washer's circuit with other high-draw appliances like space heaters or hair dryers.
Inspect the power cord and outlet
Check the washer's power cord for damage, fraying, or loose connection at the plug. Ensure the wall outlet prongs grip the plug firmly. A loose outlet connection can cause voltage drops under load.
If the outlet feels warm to the touch or the plug is loose, have an electrician replace the outlet.
When to call a professional
If the outlet voltage is consistently low throughout your home, contact an electrician. If the voltage is normal but PF keeps appearing, the washer's power supply board may be faulty — contact a Haier service technician.
