Melissa for Model Number 110.47512602 Hi, I have a Kenmore HE2 washer that keeps giving me the f21 code. I check the filter and hoses for anything stuck in them. Changed out the pump and pump motor. Neither have done the trick. I have also been starting to get an SD code (I use HE soap and the recommended amount or less). Also, when I try to clean the washer it detects a load in the drum, but there is nothing in it. Any ideas what to do?
Answer Melissa, The F21 and the SD error codes would indicate an issue in the water level switch W11417619 or air tube W11252474 between the switch and the drain pump, since you've eliminated the drain pump and hoses as the possible problem. Disconnect the air tube from the water level switch, Blow in the end of the hose, check and make sure the hose isn't kinked or twisted, etc. Blowing into the hose will usually clear any sediment or debris that accumulated inside the air tube. If the F21 or SD issue persists, replace the water level switch. Read More... Answered by AppliancePartsPros.com | Friday, September 19, 2014
