LG Washer error code E3

What it means

Drain motor error - there is an issue with the operation of the drain motor.

Likely causes

A problem with the drain motor operation
Water inside the washer may have frozen due to cold weather

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

Unplug the power cord, reconnect it, and attempt to operate the washer again
If the machine may be frozen, thaw the tub and drain hose using warm water

When to call a pro

If the E3 error occurs repeatedly, the drain motor may require inspection by a technician - request service.

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.
