Product review (5 stars): Works Great
Old drain pump started making noise, then failed completely, which generates F-21 failure code on the display.  I did the normal troubleshooting, cleaning the screen in the pump and check the drain hose for clogs.  No help.

So I ordered this one as a replacement.  Replacement was straight forward, two hose clamps, electrical connector and two bolts hold it in.

One caution, if the machine is full of water, make sure you can put a bucket under the opening to drain the water.  Or use a wet/dry shop vac and suck the water out through the drain hose.  There is about 4 gallons of water.  Even if the Drain Pump worked enough to empty the machine, there is still a gallon of water.  Too much for a few bath towels.
