Question about Whirlpool duet Washing Machines
I have a duet sport WFW8300SW02 which I am having problems with. During a wash cycle it made it to 2 minutes left and then stopped working. I started the cycle again and this time it made it to 9 minutes left. It would not spin out or drain. I unplugged it, drained it manually and opened the door manually to remove the clothes. When I plugged it back in and power up, it will lock the door and then do nothing. If I hit a button, the Add A Garment light will blink. I ran the diagnostics and am getting F26, F20 and F21. I did remove the MCU to take a look at the back of the board as I read in another post here and there is no blackend area or short that I can see. Does this sound like a door latch issue? Should I replace that? Or could it still be the MCU?
Here is the code meaning
F26 is for door lock - do you hear the door lock one time or with click sound repeatedly.
F20 no water entering - do you check water coming into washer
F21 long drain-do you take a look of pump filter
Another possibility is the pressure switch was bad.
Hope you can figure out the issue.

what I have found is that the washer thinks it is not pumping out .. if your drain pump is clearly removing the all the water in a good time... then the problem is your pressure switch...it is telling the computer that it still has water in the machine...
replace the pressure switch and it will solve your f21 error.
It is a round unit on the right hand side on top...with a tube and wires going to it...let me know if it helps

This solution is the best! Thank you so much. You just saved us a whole bunch of $$$ and frustration. 1 baby sock and 1 pair of undies later - the machine is back to normal. THANK YOU!
unplug from power source...remove front lower panel (3 sheet metal screw wirh 1/4" drive head located on the lower lop of the panel)...open pump strainer (looks like a large stove knob, Turn it counter clokwise, lookout! lots of water will gush out... back flush the pump by filling the outet of the drain hose ( this may dislodge debris that may jam your pump)...re-assemble, plug to power, and turn-on. In my case, there was a piece of a pencil lodge in the pump impeller. I had to disassemble the pump. it can be done if you are patient and able to figure out how the plastic thing come apart. Good luck! If all else call the pros!

i had the same problem. take the bottom cover off of the front of the washer. on the right you will see a round white screw off cover, it is very tight, it unscrews counter clock-wise. pull this out and see if there is any debris in it. if you look into the hole on the right side there is a hole about 1 inch round, this is the pump opening. you may have to take the gray drain hose off of the back of the pump housing and feel if anything is stuck in there, in my case there was a penny stuck side ways blocking the flow of water. after i took it out the washer has been running great again. this is obviously a design flaw, that something that large could manage to get that far, lucky for me it didn't damage the pump impeller. hope this helps. this should take care of the SD and the F21 error codes.

"F21" is a Long Drain error code. This indicates that you have an obstruction in the drainage system. More than likely you probably have a clog in the drain pump. The following link explains:
Included is a follow-on link that explains how to check the drain pump to clean. You may also have to remove the inlet hose that runs from the bottom of the wash tub to the inlet side of the drain pump. Debris can commonly clog in this area as well causing the drain cycle to fail.
If you have any questions about this repair, or need additional assistance, please let me know. I hope this helps you.
NOTE: If these preliminary measures do not correct your problem, you may have to replace the drain pump. It does not take much to damage the pump impeller or motor. Since the error code is generated if the drain cycle exceeds 8 minutes, if the pump is damaged and can't pump at the required volume, the error code will continue to appear until the pump is replaced.
