How to replace Washer Main Control Board. The repair company replaced the shocks & the motor duet to error codes but the time kept reverting back during a cycle and then wouldn't finish a load. They wanted $350 to replace the control board. I found it on here and a video from here on YouTube. It took just a few minutes to replace it and now it's working just fine.
