Is there any way to purchase the impeller only? Motor is fine. I had a "buzzing" noise while the washer was in a wash cycle, but no noise while draining. Turns out, the chopper ate itself. This caused the end of the impeller to get a little rounded out. Hate to have to buy a whole pump assembly for a little plastic part.
Here is what I did, I looked at other models that use this pump (KUDP01DLBS7).
It showed the impeller/seal kit (Item 22 in Section 8).
Unfortunately it also shows it as "out of stock" which often translates into obsolete.
You will have to call to find out the availability.
Also I am not 100% sure it will fit so it is a gamble.
