I've never had a 'stuck' impeller not have I even given the shaft a twist before had...just hookup/power up and use it
Disassembling is easy....and not messy
I only do it AFTER running clean rinfse/flush water thru it
1. Remove the 4 acorn nuts at the top of the pump assembly
2. Pull the top sewer adapter away from the pump (be careful with the the gasket)
At this point remove anything wrapped up around the chopper blade. This may be all you need to do.
3. Remove the chopper blade assembly by gripping the motor shaft under the blade with a small pointed vice grips and remove the nut holding the chopper blade.
4. Now remove the pump assembly, being careful with the next gasket. Examine the rubber pump impeller. Replace if it has damaged vanes.
Reassemble in reverse
20 minutes R/R
