"F21" is a Long Drain error code. This is an indication that you have an obstruction somewhere in the drainage system. Most commonly, there is something lodged in the drain pump or inlet line running from the wash tub to the pump. There is a white screw off cap on the drain pump that you can remove to inspect the pump impeller and clean. The following link explains how:

http://www.fixya.com/support/r3608588-f21_error_code

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 and small articles of clothing such as socks or under garments can become lodged in this area as well causing the drain cycle to fail.

NOTE: A "SUD" error code can also often occur in conjunction with the "F21" error code. This is due to air being detected in the drainage system, which can occur if the pump is not running, or if you have an obstruction BEFORE the pump. You need to remove the inlet hose from the pump to ensure it is also not blocked. Correct your drainage system fault, and the SUD error (if displayed) should go away.

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. If the pump requires replacement, the following link explains how:

http://www.fixya.com/support/r3574350-replacing_the_drain_pump_in_a_front_load

These are both very simple repairs that you can perform yourself without the assistance of a repairman.

NOTE: For an explanation of all the error codes, each one of these washers comes with a technical data sheet inside.

To access, you will need to remove the lower toe panel under the door. The access screws are located under the bottom front edge of the panel. You may have to prop the two front fett of the washer up for better access ( a 2x4 works well for this). With the screws removed, the panel should drop down, then come off. If the tech sheet isn't directly behind the panel, it will be affixed to one of the interior cabinet walls.

The tech sheet lists all error code definitions, troubleshooting data, diagnostics procedures and wiring diagrams. I mention the tech sheet because you may need it to troubleshoot this error code.

Read through the information provided and if you have questions, please post back and let me know. I hope you find this information helpful.

Will not spin or drains shows F21


The F21 error on a Whirlpool Duet washer means the unit was draining slowly. This can be caused by a blocked outlet hose (kinked hose, for example), excessive suds from using non-HE detergent or too much detergent, blockages in the drain pump filter (coin catcher), or a problem with the pump.

You should be able to clear the error by pressing Pause/Cancel twice. Check your outlet hose. Then unplug the washer. Have a bucket handy to catch the water when you access the pump. Remove the toe panel from the bottom of the washer. There are three screws to remove; then you need to lift the panel slightly and pull it forward.Check the filter for foreign objects.

Test the washer by selecting a cycle and running it with no clothing or detergent. If the unit still fails, then the pump, pump motor or the pressure switch is bad. However, you should also check the wiring to the unit.

I hope this helps. Please add a comment with the model of your washer for specific directions and parts information.

My front loading Crosley washing machine is showing error code 21. What does that code mean?


Can't remember the exact error code, but my crosley front loader would not spin. I found out this was because all the water was not being pumped out. I wash a lot of dog blankets and found out the drain basket was completely blocked. I was able to remove and clean from the back and this fixed my problem. I guess it could be the pump but check this basket first. The way I did it from the back was hard so I suspect there is a better way to access the basket.

Error message SUD and F21 even after unclogging the filter


Push the pause/cancel button twice to clear your message. Then run through a rinse/spin cycle. Next try a normal load without any detergent. SUDS is usually from too much detergent. If this fails, checked the hose for kinks. Check connections and if all that fails, you will probably have to replace the pump. Good Luck!

F-21 code several times. We clean the pump. Start again the rinse/drain and spin cicle, and now present sd code and later f-21 code. What we need to do.


I have the manual for this machine. Under "Code 21" it says the following:
"F21" (Drain Problem) Select STOP twice to cancel the cycle. Unplug washer or disconnect power. Check the following: Is the drain hose kinked? Is the drain hose frozen? Is the drain hose clogged? Is the drain hose more than 96" (2.4 m) above the floor? Plug in washer or reconnect power. Re-select cycle and press START. If the problem remains, call for service.
For "SUDS" code, the following:
"SUD" (Suds Routine) When excessive suds are detected, a suds routine automatically starts. This routine removes extra suds and assures proper rinsing of your garments. "SUD" is displayed during rinsing to inform you that Suds Routine was activated. Use only HE (High Efficiency) detergents.
Here is some more information that may help you as well:
"F" Codes other than F20, F21 and F22 Select STOP twice to cancel the cycle. Select DRAIN & SPIN if there is excessive water in the washer. Re-select cycle and press START. If the problem remains, call for service.
I hope this is of some help to you, Please rate and comment, Thank You

Hi from retired Englishman in SW France,

I'm sorry but 'F21' (along with F16,18,20 and 22) for Whirlpool (Kenmore) washers decodes as 'control unit failure' rather than a specific drain problem (which tends to be indicated by 'F2').
I fear it calls for an engineer. Sorry again ;-0(

If this has assisted and/or clarified the situation for you please consider a 4 thumbs up on our rating.
Thanks and good luck.

Error code f 21, what does this mean?


The error code F-21 refers to Long Drain. The washer has sensed that it has not drained out completely and cannot go into further cycle.

If yours is a HE 2 washer, afer few minutes, Sd error will be displayed and then after couple of minutes F21 error code will appear. Water valves will be turned off and stops running.

If yours is a HE front load, when drain time exceeds 8 min, F21 error will be displayed. The water valves will be shut off and pump will stop running.

Generally, by re-storing the power to washer, it may fix the problem.
You may press the pause or the cancel button twice to clear the display.
You may have to double check the drain hose to see if there are any kink, clogs.

Also, you may unplug your washer, turn the circuit breaker off for 1-2 minutes and then plug it back in to check if it works. After this, check to see if the washer drains.

Water remaining in washer after completed


any error codes maybe f21,take the bottom panel off, you'll see the pump on the right hand side,use a pair of plyers to unscrew the middle part of pump,if you have a shop vac turn the middle part counter clock wise slowly when water starts coming out vac it up,also put a towel under the pump to catch water,when it's drained unscrew the middle part all the way and take it out and clean out the pump,feel around inside to make sure nothing is stuck in the impeller of the pump, try blowing through the other end of drain line to see if there is a block in it,put it back together and run it,put it on spin drain and make sure water is pumping out the drain line,if not the pump could of been damaged and you need to replace it

It keeps coming up with the f21 code


"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:

http://www.fixya.com/support/r1484065-f21_error_code_whirlpool_duet_kenmore

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.

NOTE: The "SUDS" error can commonly occur with the F21 error code as this is usually generated when air is sensed in the drainage system.
