I've gotten this error a couple of times before and have always been able to clear it by cleaning the drain filter. This time, however, the drain filter was clear. I tried running a load again and I noticed that it didn't sound like the pump was starting. I guessed that the pump itself was bad, so I ordered a new pump and paid a few bucks extra for next-day delivery. Since I'd already pulled the machine out and taken off the back cover to get to the drain filter, installing the new pump literally took less than 5 minutes. There are only 4 bolts, so as long as you have the right type of socket to get into the very tight area (would have been easier if I could have tipped the washer and accessed it from the bottom, but there's not enough room to do that in my laundry room) it's a very quick procedure to take the old one out and put the new one in. Appliance Parts Pros made it super easy to find the exact right part and I was able to fix my own washer and save a lot of $$.
