What does i mean when the washer has an error code F-21 and Sd

Hello,

Welcome to FixYa.

The "F21" on your model of washer indicates the machine has detected a fault or obstruction in the drain process.

Chances are the pump itself is being obstructed by debris or some other foreign object as opposed to being faulty, although the faulty pump can`t be ruled out...yet.
This is also the reason for the "suds" message.

Here`s how to check it and clean it...

Though it being full of water may make it messy. A wet-dry shop vac is handy in this situation.

If it is in a position that allows you too lean it back against something strong or a second set of hands it will help if tilted back almost all the way.

Careful not to hurt the machine or yourself, and undo the fill hoses and drain hose.

**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 removable filter. ( **see image below...this is were a wet-dry 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 removable filter.

4) Re-insert the filter and before placing the panel back run a test rinse/drain cycle to inspect for leaks and to verify 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 hose/rubber bellows from pump to tub...back-flow ball...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 couple hundred bucks !

Now You should be good to go. Re-attach the lower panel and you`re back in business.

**NOTE: if this still fails to remedy the F21 or if it returns immediately during the next drain you may require a pump unfortunately...part # 280187 available at "searspartsdirect.com" "repairclinic.com" etc.

**This however can also be caused by the back-flow ball inside the bellows which connects the tub to the pump. There is a large clamp which secures it to the tub, but if you remove it to clean out all the dirt built up inside, make sure you get it good and secure when putting it back.**
Let me know how it goes and if you require further assistance.

The F21 error code indicates a long drain. Here are some tips that should help you resolve this problem:

• Check your washer drain to make sure that it is draining properly.
• Check the drain hose for kinks and clogs. Make sure that it is installed properly per the instructions in your owner's manual. An improperly installed drain hose can prevent the washer from draining properly.
• Check for excessive suds in the washer tub. Excessive suds can prevent the washer from draining properly and will result in the F21 code. Make sure that you are using the proper amount of HE (High Efficiency) detergent to prevent excessive suds.
