I would inspect the pump first for a problem with something in the pump or broken part of the pump
unplug the unit from the power before checking the pump
be prepaired for some water when you remove the clean out plug on the pump

Humming sound from the washer


Sounds like the pump is locked up for some reason could be something stuck in it,I have pulled a lot of nickels out those for some reason, they are the perfect size to get down into the pump and get stuck.

Whirlpool washer stuck with F-21 error


"F21" (AKA SD) is a Long (SLOW) Drain error (LD). 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...



If you experience a problem where the washer does not drain properly or the drain pump makes excessive noise, here's the information you need to check the drain pump:

Symptom: PUMP IS RUNNING, BUT NOT DRAINING PROPERLY.

1. Unplug the washer while servicing inside the unit.
2. Remove the lower kick panel under the door by removing the three 7mm screws under the bottom edge of the panel. HINT: Use a couple of blocks of wood to prop up the front feet of the washer to gain better access to the screws. Once the screws are removed the panel should drop down, and then pull off. If the panel becomes stuck, a slight tap on either side will dislodge it.
3. Locate the drain pump. It will be located directly under the wash tub (it is the only pump this washer has).
4. There is an access removal cover on the pump that can be removed to clean out the trap. BEFORE doing this, it is strongly recommended that you remove all residual water from the wash tub & drain line or you will have about a gallon or so inside your washer and on the floor to clean up.
5. Here's a helpful way of quickly removing the residual water. If you own a wet/dry shop vac, remove the drain hose from the standpipe at the wall and pull a vacuum with the shop vac. This will empty the wash tub, pump and drain lines. If you don't own a shop vac, grab a bunch of old towels and open the access on the pump slowly so that it comes out at a trickle. Allow the towels to soak up the majority of the water. Close the access and stop the water if you need to get additional towels.
6. Open the pump access and remove once you have all the water drained. Check the drain pump for foreign objects and debris. Check the pump impeller and make sure there's nothing caught in it. Items as small as toothpicks or cotton swabs have been known to stop this pump from working.
7. Clean out the pump thoroughly and reinstall the access cover. Make sure the cover is snug, but do not over tighten.
8. Place the drain hose back in the standpipe (IMPORTANT - DO NOT FORGET!).
9. With the bottom panel still off, plug the washer back in and select the following on the operator console - DRAIN SPIN, NO SPIN, and then press any button under OPTIONS 4 times (it must be the same button). "C00" will show on the console display as the washer begins diagnostics mode.
10. Check the drain pump for leaks as the washer fills. The pump is gravity filled and will hold water even it is not pumping. Allow washer to run through diagnostics until it begins the wash tub tumble cycle.
11. At this point, you can stop the diagnostics procedure by pressing PAUSE/CANCEL 2 times. The drain pump energizes and the washer will begin to drain.
12. If the drain pump works normal and there are no leaks detected, reinstall the bottom panel and tighten screws.


NOTE: It is normal to have residual water left inside the wash tub under the wash basket. This is why it is important to leave the door ajar when not in use so this water does not become sour.

I have a whirlpool front load washing machine model WFW8300SW00


Hay Crab.
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

Whirlpool duet sport wfw8300sw00 f-21 error


Unplug the machine. Unscrew the 3 screws under the front edge of the washer. The service technician manual is attached to the panel that slides down and off. Find F21 code. See suggested procedures. Note: My drain pump filter had a baby wash cloth in it along with some change that was disrupting the flow. It is exceptionally easy to remove, clean, and reinstall. Just line up installation notches when reinstalling. Whirlpool should have mentioned this filter in the User & Care Guide, but I could not find it anywhere in there.
