Machine stopped three of four cycles after replacing the bellows for a leak. Thought I may have pulled some wires from the user interface to the control unit loose. Checked that - no problems. Figured it was the Control Unit - so I ordered one from Appliance Parts Pros. The old one was a bit tricky to remove, and I finally took off the bracket behind the user interface panel to push it aft to free it. Wasn't the problem so I returned the new CCU to Appliance Parts Pros and ordered the Motor Control Board. Thanks for allowing the return, Appliance Parts Pros. Installed the new Motor Control Board and machine started right up. Fix took 15 minutes, troubleshooting a month.
