Joseph F Point Roberts , WA April 10, 2015 Appliance: Maytag Washer MVWB850WL1 Maytag Washer Mvwb850wl1: Zerror cpde f01. How to replace Electronic Control Board. Tried to clear water pressure line - that was clear and then decided to get a new control board as this seems the only fix. Appliance Parts were helpful in identifying the correct part # and with thequick shipping. I didn't have to even resort to going to the laundromat. Replaced the board in a few minutes and washing machine is now up and running!! Thanks 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
