My washer states over suds on every other load and now F21 is comming up. What does this mean?

The SUD code is a result from oversudsing. BE SURE to use an HE detergent. The f21 code shows the machine is taking too long to drain as a result of too many suds. Start the washer with a cap full of fabric softener and nothing else. If it goes through the cycle as it should then you're good. If it doesn't, then replace the pump.

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!

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

Hello again,
I found your manual. If you like to get it, go HERE. This is what it says about "SUDS" action:
"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.
Near the bottom of the troubleshooting page, it gives this for errors:
"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.
It doesn't specifically state what "F35" is, so I can only suggest these steps, and see if this solves your problem. If it doesn't I would be inclined to believe that there is a problem with a part, which would probably be serviceable by a tech from Sears or their partner service company.
Hope this clears it up for you.
Please rate and comment. Thank You

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.

Place a shallow pan on the floor beside the washer and then pull the drain hose out and place the end of it in the shallow pan to see if the washer will gravity drain. If it does, then excessive suds or a drain pump problem could be causing this failure. If the water does not drain or drains extremely slowly, you could have a clog in the drain system of the washer.

The SUD message relates to overdose of detergent detected during the Wash Cycle.
This may signify a bad pump, an extra heavy load, excessive detergent or excessive suds.
If too much detergent was used, run the washer through a Rinse/Spin cycle, then a Normal cycle, without adding any detergent. This should clear the unit of the excess detergent.
Check the drain hose and make sure it is not plugged or kinked. this seems to be the reason as to why your unit is not fixed even after trying to solve F21......

F28 is a communication error which usually means there is a connection that has come loose. Removing the top and unpplugging and replugging the connectors in will fix 75% of these codes. If the bottom toe panel is not on it will also give you an F28.
Good luck

F21 indicates that the washer is having problems draining. Check the drain hose to see if it is kinked or if there is an obstruction in the hose.

SUD comes on every time excessive suds are detected. Not using the proper detergent will set this off faithfully. The machine will run a cycle to remove the excessive suds before completing the wash cycle.

You need to clean the drain filter by removing the 3 screws in the bottom of the front panel. Then you will see a white twist cap. Remove the filter and clean it out.

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.
