![]() Have a Samsung washer - top load that only starts when it wants to. Normally pushing the start button after selecting the cycle - it won't start, just beeps. constantly adjusting cycle and hitting start may get it to work. I took out the control board (wax or gum coated) - don't see anything obviously wrong. Put in another used control board - washer works perfectly (start button works).
Is there a way to remove this wax / gum off the board ( DC92-01021H) ? I'll post pics tomorrow morning. Most likely bad caps ? I read on another post - bad voltage regulator. thanks Last edited by SMDFlea; 11-24-2020 at 03:22 PM.. |

![]() appears that all functions work -rotating the knob selects any cycle. the only fault is the start button doesn't start the cycle that was selected. The start button is acknowledge as I hear a beep when pressed. I can get the washer to start but is totally randomly. can't figure out sequence to get it to run consistently.

![]() Good job! where is the cap located? This will help lots of people. The conformal coating is always a pain to remove, yous is more likely to be silicone based conformal coating. Washer model number?

![]() in the pic - it is the cap with the black x on top of it - top of the board (actually easy to remove and install new one). thought I put model # in topic - my mistake. Samsung washer model #WA50F9A8DSW/A2. Is there an easy way to remove that silicon coating ? I spent a lot of time peeling it off.
