LG Washer Error Code PF

LG Washer PF Error Code — What It Means and How It Affects You

The “PF” error code on an LG washer stands for “Power Failure.” It appears when the washer experiences a loss or interruption of electrical power during operation. This can be caused by a temporary outage, a tripped circuit breaker, a loose power connection, or an internal electronics fault. When PF occurs, the washer typically pauses the cycle and displays the code so you can restart or reset the machine safely. For many users the immediate impacts include interrupted wash cycles, wet or partially washed loads, longer overall laundry time, and the inconvenience of having to restart cycles. In some cases, repeated or unexplained PF errors indicate an underlying electrical or control-board issue that could risk recurring failures, potential damage to electronics, or—rarely—safety concerns if there’s burning smell or visible arcing.

Common Causes

• Temporary power outage or utility interruption
• Tripped circuit breaker or blown fuse on the home circuit
• Loose or damaged power cord or plug
• Faulty or overloaded wall outlet (poor connection or worn receptacle)
• Voltage fluctuations (brownouts or spikes) from other heavy appliances
• Damaged wiring or wire harness inside the washer
• Faulty power control board or main control board (electronic failure)
• Bad door lock or control-interrupting component that stops power to motors

Troubleshooting Steps

1. Safety first: Before doing anything, pause the washer, and if you must inspect the appliance, unplug it or switch off the dedicated breaker to avoid electrical shock.
2. Check your home power: Verify whether other appliances or lights in the same area are working. If there’s a wider outage, wait for power to be restored.
3. Reset the washer: Unplug the washer for 1–5 minutes, then plug it back in. Many PF codes clear after a full power-cycle and pressing Start/Pause or Power again.
4. Inspect the outlet and cord: Look for a loose plug, frayed cord, or discoloration at the plug and the outlet. Try plugging the washer into a different, known-good outlet (do not use an extension cord long-term).
5. Check the breaker: Open your home electrical panel and confirm the washer circuit hasn’t tripped. Reset the breaker if necessary, and watch for immediate re-tripping which indicates a wiring or appliance fault.
6. Reduce load on the circuit: Avoid running high-draw devices (microwave, air conditioner, oven) on the same circuit while the washer runs.
7. Run a diagnostic (if available): Many LG washers have a diagnostic/self-test mode that can reveal stored error history. Consult your model’s manual for the steps to enter diagnostic mode.
8. Observe for repeat PF occurrences: If PF returns regularly during normal power conditions, the cause may be internal (control board, harness). Note when it happens and any accompanying symptoms like smells, sparks, or failure to spin/drain.
9. Inspect internal wiring and connectors: If you are comfortable and the unit is unplugged, check internal wire harnesses between the inlet, control board, and motor for loose or damaged connectors. If unsure, skip this step and contact a technician.
10. Contact LG support or a qualified technician: If PF persists after basic checks, or you see signs of electrical damage, arrange professional diagnostics and repair—especially before replacing major components.

Maintenance / Prevention Tips

• Install the washer on a dedicated 120V/240V circuit (as recommended by the manual).
• Use a properly rated surge protector or whole-home surge protection to guard the electronics.
• Avoid using extension cords or adapters long-term; plug directly into a grounded outlet.
• Check and tighten wall outlet connections periodically if you notice looseness or arcing.
• Keep the power cord in good condition—replace it if frayed or damaged.
• Label the washer breaker in your panel and ensure it is not shared with heavy-load appliances when possible.
• Do not overload the washer—heavy loads can cause repeated motor strain and electrical tripping.
• Schedule periodic inspections by a qualified technician, especially if the washer is older or used heavily.
• Avoid running several major appliances at once to reduce voltage drops in your home wiring.
• Keep the washer area dry and free from water intrusion that could reach electrical components.
• After a storm or power event, visually inspect the washer and surrounding outlets before using.
• Follow manufacturer instructions for grounding and installation during setup.
• Consider whole-home voltage monitoring if your area experiences frequent fluctuations.
• Keep firmware/software (if applicable) up to date by checking LG support for updates.
• If you replace parts, use OEM or approved parts to avoid incompatibility and further errors.

Conclusion & Safety Notice

PF is a common indicator that your LG washer experienced a power interruption. In many cases it is resolved with a simple power-cycle and ensuring the outlet and breaker are functioning. However, if PF repeats, is accompanied by burning smells, sparks, tripped breakers that reset immediately, or if you’re not comfortable performing basic electrical checks, stop using the appliance and contact a qualified technician. Appliance electronics and home wiring can present shock and fire risks—do not attempt complex internal repairs unless you are trained and the unit is unplugged.

If troubleshooting steps above do not resolve the PF error or you suspect a failed control board or wiring fault, schedule professional service. A certified LG technician or licensed electrician can diagnose electrical issues safely and recommend the correct parts or repairs.
