Hi Wise Folks,
Loud grinding noise was similar to what we heard when there was sippy straw and twist-ties in there. That time (6 months ago), the noise went away after appliance person took it apart and cleaned it. THe water also flowed better, and got things clean.
Now the noise is back. I have cleaned the mascerator (1st blade/screen in sump). Did not fix the problem.
It only seems to happen in the wash cycle, not rinse. Don't recall if pre-wash/rinse.
The unit has given 8 years of service, would like more. Everything else works fine. Just the noise.
Read somewhere that it could be a second level screen, or even the impeller.
Looks like I have to remove pump to get at these.
If I have to remove the pump (even if just to replace the impeller), is it worth getting a new pump (and related seals) and new impeller--and fixing the thing? Are there other "wear" parts (e.g., sensors, water pump) that are considered fragile and should be replaced?
I am very handy, though this seems more "involved" than complicated (I downloaded a Whirlpool manuial to read about the steps).
Is it worth it?
Advice Most appreciated.
