My Whirlpool Duet Sport washer wll not drain. It gives an F-21 message. I checked the back drainage hose and it seems clear. I believe I hear something rattling within machine - perhaps kids hair pins somehow got stuck. Checked the filter and it was clear as well, is there anywhere else something could have gotten stuck?
I have had this code three separate times. The first time service man came and cleaned out the filter. This is behind the lower front panel and can be removed by hand. The cartridge style filter is located at the pump in the lower right of the unit. Have something available to catch the draining water as you loosen the filter. The second time I received this code I found a blockage in the drain hose at its bend. The third time no hose blockage, no filter clogging, but the pump impeller was jammed by an elastic strap that had made it through the filter. I removed it through the supply side of the pump seen after filter is removed.
F- 21 is an error code for a communications error between the touchpad and the ccu (main computer) check that all leds light up when selected . if so disconnect power from machine for 30 secs. try again. still a problem? check wiring for loose connections. have also seen this once with drain pump not plugger in. basically you have to find out what unit is not talking to the ccu. as for the noise when you remove "filter" the hole to the right is the impellar see if something in there. it is safe to seperate the two halves of the pump and reassemble.

Just had the exact same problem. Front panel screws hard to get at, (unit stacked) but used univeral on ratchet. Wow, how easy compared to our old stacking GE unit. Word of advice, unscrew the drain plug slowly. We had a LOT of water, and used a heavy duty garbage bag held around the drain to "catch" the water. Worked great-no wet towel mess. Thanks

I have the same problem too ??
My medium load went half way through a cycle and flashed an "F-1" error
I tried everything ....from unplugging the unit for awhile ...trying all other washing modes ...and nothing :(
Now...it is flashing "F-21" ??? after being unplugged for a few days
*repair person is coming out Friday .....the washer is 7 months young
i have tried all that you suggest and all the lights work the beeps work the machine apears to be ready to go but does not go
I'M HAVING THE SAME PROBLEM, F-21 ERROR. I HAVE TO UNPLUG AND SOMETIMES START OVER SEVERAL TIMES BEFORE IT'LL COMPLETELY DRAIN.
THIS IS AWFUL...PAY SO MUCH, THINK YOUR DOING A GOOD THING TO HELP SAVE WATER AND SUCH. I COULD HAVE BOUGHT 2 CHEAPER WASHERS FOR THIS PRICE AND PROBABLY HAD BETTER LUCK!!!
Yea I've got the same problem, I've tried unplugging it for 30 seconds...still no luck..
Waiting for a loner here..
