Steven B Westford , MA April 03, 2016 Appliance: Maytag Compact Automatic Washer MHWC7500YW0 Maytag Washer Mhwc7500yw0 / : F23 error code on a maytag front loading washer. How to replace Water Pressure Switch. Error code indicated a faulty water pressure switch. The washing machine is part of a stacked washer/dryer set. The hardest part of the repair was getting the set out of an extremely tight fit in a closet in the apartment. Once out, we took the dryer off the washer, and then removed the top panel of the washer. The pressure switch was clearly visible at the front right of the drum. A flat blade screwdriver was used to release the clips holding the switch to its mount. It was a bit tight to get my hands down to the switch to remove the two electrical plugs and the pressure hose, but not too difficult. The hose and plugs were easily reattached to the new switch and it was clipped in place. We replaced the top panel and reinstalled the dryer on top of the washer, and slid the unit back into the closet. The switch replacement itself probably took no more than 5 minutes -- most of the work was getting the unit out of and into the closet. 29 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
