I have a customer with a Whirlpool Duet front-load washing machine that I've repaired a couple times already, and I'm going again soon...anyway, I replaced the motor control board on it last time and that fixed it for a few months. Got a call recently that it was not spinning. Went over and checked all wiring connections to the CCU and MCU. Re-seated cables to CCU, no change. Re-seated cables to MCU--that got it working. In particular it was a 2-pin connector, I believe--2 blue wires. I pried the little tangs on the connector to make a firmer connection to the board and it worked fine until this weekend. I remember watching a video where the Samurai added a little solder to the pads where the connector slides onto. I wouldn't think something like that would be needed for a new board, but it seems like that's where the source of the problem is.
Does that sound like the right way to proceed here? Or might I need to replace the wiring harness?
Edit: Just to add a bit of info: The way this problem seems to manifest itself is that I put the machine into Drain/Spin mode, it runs the drain pump for a few minutes, the tub rotates back and forth slowly, then the countdown timer stays at however many minutes are left and eventually the machine shuts itself off. I'm going to stop over there tomorrow, so I'll have more exact info then.
