Answer to: Why am I getting a SUD error message?I had the same problem. I did two things: 1) Clean your drain from the wall all the way inside the machine to the drain pump. This will take some time, a star screw driver, and some large mouth pliers. use the pliers to loosen the hoses on the outside and inside of your machine. I used my hose pipe to wash the clogs and debris out. I was amazed at how much junk came out. Put all the hoses back together. 2) Take off the bottom front panel (3 screws). You will see the drain pump and a large circular screw. This is your drain filter. Unscrew it, clean and replace. This should take care of your problem.
