Kenmore HE2 Plus F21, Sd, and F33 error codes.
We researched the F21 and Sd error codes over the weekend and discovered that we should check and clean the filter, check the wiring, and make sure the drain hoses are not clogged. We have done all of that and everything checks out. During my last test run in the drain and rinse cycle we received an error code that says the Central Control Unit needs to be replaced. I'm inclined to think that the drain pump needs to be replaced. What do you think?
