Washer is making a grinding sound when draining water.

Hi, this grinding sound is coming from the pump. the pump device seems to have a broken impeller that is located inside the pump. You will not be able to replace this internal part. This device is fixed and you will have to replace the entire pump assembly.

This will happen if some debris or coins make it threw the pump housing. these debris will settle in the pump housing near the impeller and it will grind while in operation or, draining procedure. the solid debris will eventually damage the impeller and break it off the drive bolt. this will all happen in time but, it usually starts with the minor grinding sound.
