We've had this washer for ~11 years and it's been fantastic. The recirculator valve had to be replaced once, but that's it until recently. I washed some removable stair treads that hadn't been washed in a while. When I went to check on the load, the washer was off, but still full of water. I turned it back on and advanced the cycle to rinse. I heard it run for about 30 seconds, but then it just shut itself off and I saw no appreciable change in the water level. I then began to smell a "hot" smell.
I unplugged it and let it sit for a while, then plugged it back in and advanced it to rinse. This time I pulled the drain hose out so I could see how much water was coming out. There was some, but nowhere near what you'd expect. Again, after about 30 seconds it shut itself off and there was the hot smell.
I bucketed out all the water, tipped the machine back, and removed the drain pump. There was some matted fabric from the treads caught in the impeller. I removed that. I also checked the hose on the other side of the pump and found some more matted material in the hose which I removed.
I put everything back, tipped the washer back down, and tried to to run it empty just to see what happened. It filled, but when it began to agitate it stopped and began beeping. I downloaded the troubleshooting manual and went through the diagnostic mode to find the code was for the Out of Balance sensor. I'm speculating that having the machine tipped back for a while was the culpruit here. I just sort of moved the tub around and then exited diagnostic mode and tried to run the washer again. Once again, 30 seconds, shut down, hot smell.
I let it sit for a while, plugged it back in and went back into diagnostic mode. The fault code is still the one for the Out of Balance sensor. While in diagnostic mode, I also did the drain pump test. Again I had the drain pump out so I could see the water flow and it was significanlty improved from my original observation...more like what you'd expect. And it did drain the tub, though I had set the water level to low so we're not talking a whole lot of water.
Sorry for the long buildup -- here's my conundrum. My suspicion is that I more or less burned out the drain pump when the stuff was caught on the impeller...but I don't know enough to know if it could be something else. I can order a new pump from my local servicer for $77.98 + tax. Or I can have them come out and diagnose it...the service call is $74.95 + parts and labor. Based on the behavior, what do guru's think?
