LHW0050PQ washer started making grinding sound when draining. I have opened it, removed the drain pump, opened it - 3 screws to separate the motor from the cap with the impeller. I have discovered that the impeller was lose and was not sitting on the rotor. I could not figure out if it was broken off the rotor. I have noticed that I can put it back onto the rotor, it clicks and then it is sitting quite securely in its place. But with a bit of force I can get it off the rotor. I am wondering if the impeller is supposed to be sitting on the rotor solidly or it is expected to get off in case if something blocks it to prevent the motor being blocked and burnt. Reassembled everything, tried to run a short cycle - the sound seems to be fine and the drain is definitely working properly. Should I start thinking about new pump assembly or this is something known?

True. My fix did work for a couple of cycles but then the impeller went off the rotor again. Since I knew this was quite possible I was ready to get the part. So, 5 days and $126 later I have replaced the pump with the new one :) And now it is super-quiet, first I was not even sure if it did pump the water :)

The job is really simple and very doable for an average DIY. I think the most difficult part is actually to move the machine to the position suitable for opening it :)
