I have a Maytag 4000 series model MHWE400WW01 washer. I got an error code of F20. I unplugged & got the rinse & spin cycle go. I retried a wash, it did the same thing but now will not power up. I unplugged and I had to press and hold the door lock to get the door to unlock. I'm replacing the water intake hose because it seems the valve is faulty. However, I still cannot get the machine to power up. Is there anything I can do to get the machine on?
