My Repair & Advice
I looked up the code in the manual and online and it told me that the machine was having a problem draining. I pulled the cover off the front of the machine and found the drain pump's clean-out. I started to unscrew the cover and a lot of water started leaking out, so I re-tightened the clean-out cover and got my shop vac. With the shop vac nozzle right at the clean-out, I unscrewed the cover again. It took awhile to suck out all the water in there, but it did not make a big mess. There was probably a couple of gallons in there. Anyway, there was some debris in the clean-out which I got rid of. I assumed this was the problem and that is was fixed. I put it all back together and ran a rinse/spin/drain cycle and once again, the F21 error code appeared. I took the machine all apart again and used the shop vac as described above to get rid of all of the water. This time, I inspected the clean out and removed all of the other drain hoses to ensure there were no other clogs. All of the hoses were clear so I concluded it must be the drain pump.
I ordered one from AppliancePartsPros.com and paid the extra $$ to have it expedited. The video on AppliancePartsPros.com on how to replace the pump was crystal clear and 100% accurate in terms of what was involved in changing out the pump. Getting the rubber hose with the sporing clamp back on the drain pump was a little tricky, but the entire repair was easy and took me 10-15 minutes.
