Whirlpool Duet Sport Front loading washer and dryer with error code

My Whirlpool duet Sport front loading washer stops and flashes the F21 error code with EVERY load of wash. You have to restart the washer or start a rinse or drain cycle to finish the load. Every load of wash takes fOREVER to do. The code says it stands for a drainage problem but we have done everything including replacing 100 yards of outside drainage. HELP.

Re: Whirlpool Duet Sport Front loading washer and dryer...

An easy Fix. Take off the kick panel, 3 screws 1/4 inch. Make sure you have a shop vac ready or a lot of towels as there will be some water. Always disconnect power to washer and dryer, and turn off water to washer. Your filter most likely is clogged with change, screws, lint, and other household stuff that we leave in our pockets! Unscrew the cap on the filter, easy to find, since you have the kick panel off! Take everything out of the filter. Take your shop vac and **** out remaining stuff in hose. Also, **** up any water that has leaked in and around the washer. Screw the cap back on hand tight, put the kick panel back on, turn your water back on, plug it in and there you go! Maybe takes an hour and saves you a repair bill. If you are not comfortable with this procedure then call a maintenance person that is qualified. 775f844.jpg

Whirlpool duet steam washer error f21

The F21 code is a ' drain issue ' --- if you remove the bottom panel from the machine you will see the water pump right there,, just in front of the pump you will see a clean out area,, unscrew counter clockwise and remove the catch screen,,, it most likely has a few things in it ,, clean out - re-install and start the cycle. and the F21 code should be gone AND washer is back up and running.

F21 clogged line on a new Duet Sport less than a year old???

Hi, regarding the F21 Error on the Front End Whirlpool Duet, I was able to resolve the problem with the instructions from here, just want to stress cleaning out the filter by removing the front panel. Very easy and the error code is now gone. (screws are underneath front panel at bottom, remove stacker drawer for easy access, remove screws, pull panel off, remove the filter cap, turn to the left and pull out-that's where you will locate the clog.

What does f21 on washer mean?

Hi, this advice is for Kenmore Elite and Whirlpool Duet model FRONT LOADERS displaying the “F21” error code.

“F21” is a Long Drain error. If the drain time exceeds 8 minutes this error code will be displayed. In addition, a “SUDS” error may also be displayed. This may be an indication of a drain pump problem and/or clog in the drain line. You will need to check the following:

  1. First, attempt to unplug the washer for at LEAST 30 minutes to reset the Central Control Unit (CCU). Sometimes this is all that is required to correct momentary glitches with the unit. If the error code returns, proceed to step 2.
  2. Check the drain hose to make sure it is not kinked or clogged.
  3. Check the electrical connections to the pump and ensure the pump is running.
  4. Remove the drain pump filter and check for foreign objects and/or debris.
To check the drain pump, click on the following link for step-by-step instructions.

If the above procedures do not correct the problem, it is recommended by the manufacturer to replace the drain pump.

Take care

Whirlpool duet washer flashing sud then f21 ????????

The "SUD" error is in direct relationship the other error code. "F21" is a Long Drain error. The following link explains:

If something is preventing water from pumping through the drain pump, you will often get a "SUD" error as air is developed in the pump. Make sure you double check all the drain lines as well.

If you have questions, or require additional assistance, please let me know before you rate the solution. I hope this helps you.
