Product review (5 stars): Great deal!
Part arrived and is identical to the original unit that came to fail after many years of use.  Installed in under 20 minutes and no more F21 error code.
If I had more time, I could have taken apart the original pump and cleaned out the debris but wanted it fixed fast.

Please note that the original pump may have a single use clamp on on the outlet pipe. Simply pry that one off and use the screw type hose clamp supplied with this unit.  Hopefully this one will last about as long.

Always run it a few cycles to verify there are no leaks before putting the access door back on.
