I successfully repaired my front loading Whirlpool duet washer. With a gaggle of electronics, I navigated through the error codes and the (helpful) owners manual to diagnose and replace the MCU (motor control unit) at $250 a pop, or $180-ish "rebuilt", I feared a bad diagnosis and didnt want to hang parts just for the cost and experience only to find the washer didn't respond to the new part.
Fast forward to a a VERY helpful local shop that has used control boards, we validated the bad part, $50 later it was hung and life was back to normal.....UNTIL.....i saw water dripping on top of the MCU plastic protective cover (shields it from water damage). Turns out the root cause of failure was that discharge hose rubbing up against the frame and allowing water to meet with electronics (a bad combination). Fortunately, I had the back of the machine off while doing the shakedown run and shut-er-down in time before history repeated. Discharge tube replaced, life is back to normal for a reasonable sum of $$. It took some time, and many phone calls, but it's now off the project list, and frosty beverages are back in my future.
