The problem
The customer's LG front-load washer stopped draining. We checked it and found that the drain pump had failed, which is a fairly common problem on LG washers.
What we did
We ordered an original LG drain pump, part 4681EA2001T, and came back to install it.
First we drained the water left in the washer. Then we removed the front panel: the door boot clamp, the door lock and the panel itself. We also removed the counterweight to get easier access to the drain pump.
The pump housing sits at the bottom on the left side. We unscrewed the old pump, installed the new one and put everything back together.
Result
The new pump drains the washer normally. We used original LG parts. The total was $366, with a 6-month warranty on parts and labor.
