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…

1 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.

Phil for Model Number WA50R5200AW/US

We have had this machine for a little over two years. From day one there were problems with loads being unbalanced that got worse and worse. fina lly, I did research and discovered the dampeners are under-designed. I replaced them and the balance issue is much better. A couple of loads before I changed them out, when I opened the lid and turned on the power the DC (open lid) fault would show. Once I close the lid I can start any cycle but I cannot pause to add or rebalance and I cannot use the Waterjet because it is in fault mode with the lid open. My suspicion is that the banging and vibration for being out of balance so much has damaged the control panel. Before I order this expensive part I am looking for reassurance that this is the problem and not something else or that there is a repair I can make to the panel.

Phil, Based on the information provided I would recommend checking the lid switch with a meter for proper operation and then checking the wiring from the lid switch to the control before replacing the parts.

Gene, Typically when the unit will not go into the service diagnostic mode it will be an issue within the main control board that would need to be replaced.

Fred for Model Number WA50F9A8DSP/A2

This top load washer will not lock. I unplugged it and plugged it back on and got the same scenario. I replaced the latch(lock) unit, then the main board and got the same response. After another day, I tried starting it and it worked for 3 cycles to completion. I waited the next day and the unit will not work. In all these processes, the displays all came on. It is when I tried starting it that nothing happens even though the sound pings when you press the start button but does not latch. Any ideas? thanks

1 Answer

Fred, you may want to inspect the magnet DC61-03184A located in the door assembly for any visible signs of a break or misalignment. If this magnet is not seated properly or is broken, then it can prevent the washer from sensing that the door is closed.

Shawn, Based on this information, the main control board does sound like it would be the cause for the unit to not start and operate.

Joe, With the start button not working this would most likely be caused by a display board that is faulty which is part number DC92-01311C.

Tony, you will want to check the hall sensor by going to cn1 on the control and reading from pin 2 to 4 and then pin 3 to 4. It should read 2-4M ohms. If not, then you have a bad hall sensor. If they do read within that ohm, then you have a bad control board.
