    Whirlpool Duet Sport washer stops and flashes F-21.Whats the problem and how do i fix it?

  • Anonymous Dec 26, 2007

    I have had my Whirlpool Duet for a year and the F21 code flashes and stops every load of clothing. The code says that their is a problem with drainage. We even invested in digging up 100 yards of drainage in the yard and replacing it thinking that maybe something was wrong. IT DRIVES US CRAZY!!! I wish I had never purchased this set. Does anyone know how to make it STOP!!! I would love to do ONE load of clothes without it stopping.

  • buzzben Feb 01, 2008

    Same problem, F21. Tried replacing the pump, didn't help. Had a repair guy out and he dumped 2 gallons of water in the empty tub, ran a drain cylcle, and it worked. 3 loads later, F21 is back.

    Of course my unit is 25 months old, just past the 24 month warranty. I wonder if there is a time bomb in the electronics. ;-)

  • die_tryin_45 Dec 28, 2008

    I had the same F21 fault code as well......pull the front bottom cover off. ( 3 1/4 inch machine screws.) There will be a big white drain valve on the bottom right of the washer. Open this valve open slowly with something under it catching all the water. I slowly opened it not unscrewing all the way ( took 3 pan fulls.) to empty. I personally found .63 cents, a nail, a ink pen, 2 dryer sheets, and lots of dog hair. Kinda gross job but well worth not paying a mechanic to come out!! Job in total took only about half hour. Thanks

    Response by "die tryin 45" was useful, and solved the problem , however this is the third time I have had to unclog the drain valve, and this time it was clogged with a sock and a wash cloth. It's nice to know I can fix the problem in the short term myself, but it certainly seems like a design flaw if a sock and a wash cloth can clog the drain

  • Tmarroccel Jan 19, 2009

    Seems like this is a manufacturer's defect - My machine is 14 mos old and is now having the same problem. Thanks for the tips...

  • mayoman Jan 24, 2009

    Thanks for the solution "dye tryn 45" - worked perfectly.

  • Lensman6 Feb 22, 2009

    I have F-21 and have tried everything here. I visually verified the pump is running (ran it with the white plug out and can see the impeller moving). I cleaned lint from the hose coming from the basket to the pump (minor) and removed and checked the outlet hose and it is clean.

    I took off the water level switch and blew into the nozzle, verified the click. I blew into the black tube that connects to the switch and could hear air coming out the bottom. Reassembled everything and still got F21. Ran diagnostics (per the secret repair manual hidden behind the bottom panel) and it fails on Rinse/Spin with F21.

    I have ordered a new water level switch to see if that is the problem but if that doesn't work, what else can I try?

I have a Whirlpool Duet and the washed load would stop and give me a F-21 error. I tipped the washer back a little and removed the three screws on the front bottom cover. There is a large white drain value, turn and open the drain (make sure you have a pan or something to catch the water and any junk inside) to remove the water. Attached to the drain is a black hose with an expanded section, squeeze this to find any loose socks, under clothes etc. I acually found three socks, a battery, a pair of tweezers and a few coins. This F-21 error is a drainage problem, don't call the repair center and pay for a serviceman, it is easy to fix yourself. I hope this helps!!

I have the Whirlpool HE 5T and it has been giving me the F21 code for about a week. I took the back off and removed the Black drain hose from the bottom of the washer. I found a pair of panties stuck in there that was not allowing the washer to drain. If you are having the same problem it might be worth it to take a look.

Solutions listed worked for me. Simply take off the three hex head screws from the bottom front panel of the machine, unscrew the drain, and remove whatever is blocking the flow of water. Don't forget to turn off power first and have a plastic bag ready to catch water. Parent of all teenage boys beware, our culprit was airsoft pellets which wedge perfectly into the drain holes. This is a VERY EASY repair.

I work on these machines, make sure you are using the recommended HE detergent, they say 2 tbls or 1/4 cup is what you need. HE stands for high efficiency and it doesnt sud up as much as the regular detergent. Alot of the time when you have too much suds in the washer that error code will appear its very common, see if that helps.

Thanks for the info. Our washer displayed the same F21 error code. Unplugged the washer; unscrewed the 3 - 1/4in machine screws with a deep 1/4in socket; removed the bottom panel; unscrewed the white plug from the sump (thanks for the tip on catching the water). Found 2 socks, coins, paper clip, and a button. Now I know where those missing socks went.

I solved my F21 problem above, figured I'd follow up in case it helps someone else.

After paying a guy $120 to come out and do nothing for an hour, I took a guess and figured the water pressure level switch was not working, which would explain why the machine thought it still had water when it didn't.

Sure enough, I took the switch out, looked it over and realized it was mechanical switches tripped by air pressure, blew a few times into the nozzle where the hose connects, reinstalled it, and it worked. When I blew, I heard a "click" telling me I was flipping the mechanic switch inside.

FYI the part is here:

http://www.appliancepartspros.com/partsearch/frame_partlist.aspx?part_id=3128700&&model_id=5136839&diagram_id=1307753

And the nozzle I blew into is facing right in the photos.

I performed this "fix" long ago and the problem has never reappeared (knock on wood).

Good luck!!

I had the same problem, error F-21. Unplugged from electric, removed the 3 screws from the bottom front cover, and slid the cover off. Use a large pan or a bucket and some towels to catch all the water....unscrew the white plug and catch the water with the pan or bucket....there will be quite a bit of water! Found a fabric softener, a bunch of lint, and a couple of coins in there. Something that I thought was kind of funny....when you take the bottom front cover off, there is a SERVICE MANUAL in a bag attached to the backside of the bottom cover which explains what all of the error codes mean.

SOURCE: whirlpool duet sport washer trouble codes

F21 is a drain error code. You likely have something stuck in your pump. Remove the lower front panel. (there are 3 #20 torx screws on the bottom of it holding it on) Once you have the panel off, the white object in the front center is your pump.
Remove the #20 torx screw out of there to make life easier. Slide the pump forward slightly so you can raise it. Now, on the front of the pump is a handel that you will need to turn counter clockwise. So after placing something underneath to catch
the water left inside the machine ( a large bowl or bucket), turn the knob slowly counter clockwise. If there is too much water for your container, screw it back clockwise and go empty your container. Repeat until all of the water is out. Once that is done, unscrew it all of the way and slide if forward. You will usually find missing socks, toys, coins and all other kinds of fun objects. While you have the trap out, reach in with your finger to the hole on the right. Try and turn the wheel inside to make sure there isn't anything keeping it from turning (bobby pins, nails,
screws, etc) If there is, you will need to unclamp both hoses on the back of the pump and remove any further forign objects. Now re-assemble the unit but leave the panel off. Run a quick fill and drain to make sure all of your connections are tight and
you don't have any leaks. Put your panel back in and you're ready to go.
Please make sure you post a rating if this solution was helpful.

First check your washer plug to see if the connections are tightly screwed. Next check your filter if you haven't for long.

here is a pic of the lint filter :) You have to take the washer apart to get to it. and look what I found stuck in mine.

SOURCE: Cannot open door on washermachine

Hello, Welcome to FixYa. The "F21" on your model of washer indicates the machine has detected a fault or obstruction in the drain process, hence it cannot spin correctly nor allow the door to unlock since it likely has some water remaining. Chances are the pump is being obstructed by debris or some other foreign object. Here`s how to check it and clean it... **Turn off the breaker at the service panel or unplug the washer from the wall socket...safety first** 1) locate the screws in front at the very bottom of the panel below the door and pull the panel down and forward until it is off. They will be either 1/4" hex head or #20 torx head screws. 2) You will immediately see the drain pump in front of you with a large removeable filter. ( this is were a shop vac and towels come in handy, also the use of the removed panel as a catch pan is beneficial...but you may still get wet ) 3) Turn it counter-clockwise should allow you to remove it and inspect it and clean it out. Make a good thorough inspection inside the pump as well not just the removeable filter. 4) Re-insert the filter and before placing the panel back run a test rinse/drain cycle to inspect for leaks and to varify the unit drains and spins now. ( If the problem still exist`s the "F21" will re-appear. If so you`ll need to check the drain hose, hose from pump to tub for other obstructions ). 5) If all appears OK after your efforts, well your efforts paid off...pat yourself on the back. You just saved yourself potentially a hundred bucks ! Now You should be good to go. Re-attach the lower panel and you`re back in business. Let me know how it goes and if you require further assistance. Thanks for choosing FixYa. Please take a moment to rate the solution provided for you here today. Good luck. macmarkus :)

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.

My machine had the F21 code and the inlet to the pump was blocked with change, bobby pins, small rocks, pieces of fuzz and clothing. Removed the front cover of the mahine and removed the cap on the front side of the pump and cleaned this trap area out. The pump motor quit humming and the machine worked like it is supposed to!

Whirlpool Duet Sport


Tinabell, I believe the code is the same for sport on the duets. Long drain. Usually I find this to be a clogged filter but sometimes the pump itself is bad. You should be able to find your tech sheet at http://www.servicematters.com/ or on the bottom of your machine. Click on technical reference, accept the terms, then technical library and enter your model number. You should be able to come up with the error codes. Catriver.
