Robert S Delaware , OH January 03, 2016 Appliance: Maytag Washer- Horizontal Axis MAH7500AWQ Maytag Washer Mah7500awq: Did not empty error. How to replace Cap, Rubber. Initially replaced the pump. However, I believe the pump went bad due to the pressure switch failing and allowing the pump to run continuously. Once I replaced the pressure switch everything was fine. FYI, the wiring harness on my washer was slightly different and would not align to t the tabs on the new switch. I had to remove the black harness guide on top of the switch and just align the harness wires to the tabs manually. My ground wire was separate from the harness. I just plugged it to the appropriate tab marked for ground. Worked fine that way. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
