Can I fix LG washer error code FF myself?

Often, yes. Safe first checks: Thaw the washing machine tub and drain hose using warm water (50 to 60 degrees C), then run a Spin cycle to test Thaw taps and inlet hoses with warm water below 50 degrees C (122 degrees F), reconnect, and test run the washer If the washer still shows errors after a full thaw and test cycles, request service from LG.

LG Washer error code FF

What it means

Freeze failure - prolonged cold weather may have caused the inlet or drain hose to freeze.

Likely causes

Prolonged cold weather has frozen the inlet hose or the drain hose

Safety first: switch the appliance off and unplug it (or turn it off at the circuit breaker) before you check anything. If water is involved, close the water supply valve too. Never open panels or touch internal wiring. Anything that involves gas lines, refrigerant or sealed systems, or mains-voltage wiring is a job for a professional - not a home fix.

Safe first checks

Thaw the washing machine tub and drain hose using warm water (50 to 60 degrees C), then run a Spin cycle to test
Thaw taps and inlet hoses with warm water below 50 degrees C (122 degrees F), reconnect, and test run the washer
If the washer will not be used in winter, remove all remaining water and keep the drain hose unbent so water cannot get trapped and freeze

When to call a pro

If the washer still shows errors after a full thaw and test cycles, request service from LG.

Repair or replace?

Try the safe checks first - many codes clear with a clean filter, a straight hose or a balanced load, and those cost nothing. If the code comes back, a service call typically costs $50-$150 for the visit and diagnosis (Angi puts an average service call at $50-$100; Sears lists a $90-$150 diagnostic fee). Get the full repair quote before you decide. If the machine is old and the quote is a large part of the price of a new one, replacing usually makes more sense than repairing.
