Julie B Spring , TX August 09, 2014 Appliance: Model MAYTAG A390 20 year old washing machine would fill to the correct level but not agitate it would spin and drain We opened the top control panel (4 screws) and found the wiring diagram. Following the diagram we determined that the pressure valve must be the problem. Ordered the part on a Sunday, it shipped Monday, and was delivered Wednesday. The replacement took a few minutes and we were back in business! Saved a great deal of $$$:) Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
