Chris Marriner for Model Number WA50R5400AV I have a Samsung washer, WA50R5400AV, it will not start and shows a DC1 error and a secondary Ub error. When you hit run, it clicks, and the lid locks, and you can hear some internal sounds like it’s thinking about running, but it doesn’t rotate to check balance. Drum will spin freely by hand. I replaced the suspension rods a year to 18 months ago, confirmed main drum nut is tight, checked voltage. Before I start throwing parts at it, thoughts?? I’m thinking Control Board…
Answer Chris, Even though the door is locked, there is a switch inside the lock that may not be activating which will tell the unit that the door is not locked and it will cause this issue to occur. Check the door lock switch terminal to make sure that it is connected properly. Make sure that there are no broken or damaged wires or terminal connection. If this checks ok then replace the main control board. Read More... Answered by AppliancePartsPros.com | Monday, May 1, 2023
