Kenmore Washer Error Code SL

The SL code on a Kenmore washer stands for suds lock. It means the washer detected an excessive amount of suds inside the drum and attempted up to three mini-cycles to clear them, but was unsuccessful. The machine locks out to protect the pump and motor from damage caused by operating against heavy foam. Common causes include too much detergent, the wrong type of detergent, or a pump that is not draining effectively.

Pressing STOP/CANCEL will clear the SL code from the display and allow you to restart the machine. However, if the underlying cause, such as excess detergent or a weak pump, is not addressed, the code will return. A reset is a starting point for diagnosis, not a permanent fix.

If the cause is detergent-related, there is no repair cost beyond switching to the correct HE detergent. If the drain pump needs to be replaced, parts alone typically range from roughly 30 to 100 dollars depending on the model, with professional labor adding another 80 to 150 dollars or more. Diagnosing the pump yourself before calling a technician can help you determine whether a service call is necessary.

Start by pressing STOP/CANCEL to clear the display and end the current cycle. Remove some laundry if the load is large, and check that you are using an HE-rated detergent in the correct amount for your load size. If the code returns on subsequent cycles even with proper detergent, inspect the drain pump for blockages or signs of failure. Replacing the pump may be necessary if all other causes have been ruled out.

You should not ignore the SL code and force the machine to run. The washer locks out specifically to prevent the pump and motor from being damaged by operating in a heavily sudsy environment. Address the cause before running another load to avoid potential mechanical damage or water overflow.
