Seeing one of these codes? It likely indicates not draining.
Bay Area LG drain issues in older homes often involve shared drain standpipes with other fixtures — when the kitchen sink backs up, water pushes into the washer drain hose. Proper air gap or check valve installation is critical. San Francisco Edwardian homes with basement laundry frequently have corroded standpipes that restrict flow.
Access drain pump filter on front-loader: open small door at front bottom, place towel and pan underneath, twist filter cap counterclockwise
Inspect pump impeller through filter opening — use flashlight to check for cracks, foreign objects, or mineral buildup
Disconnect drain hose at standpipe and blow through — should have zero resistance; any restriction means hose replacement
Test drain pump motor: disconnect wiring, apply 120V directly — pump should run immediately; no response means motor failure
The technician cleans the pump filter first — this resolves about 60% of OE errors. If the pump motor is burnt out, the entire pump assembly is replaced by accessing it from the bottom of the unit or through the rear panel. LG drain pumps (4681EA2001T) are relatively easy to swap — 30-40 minutes. The technician also verifies proper drain hose height and routing before completing service.

“My exprience with Easy Bear was absolutely superior from the beginning. I had a Subzero decide to quit. Daniel assessed the issue immediately, ordered the required new " motherboard" and had it installed within three days. My prior replacement of said part took 5 months during Covid. Daniel is smart, professional, clearly knows his trade . I most definitely will use Easy Bear in the future.”

“Daniel the technician came to diagnose what's causing our washing machine water overflowing. He didn't actually have to do anything to solve the issue, because as soon as he turned it back on, it began to work properly, but explained what the probable cause was. He was sincere and clear on the matter related to the situation. I wasn't charged for his visit as I was told ahead of time. Stanislav was also cordial arranging for all of the process. I will call them next time I need an appliance service without hesitation.”
