Perry T Plainwell , MI January 03, 2019 Appliance: Maytag Washer NFW7200TW11 Maytag Washer Nfw7200tw11: ND error code on NFW7200TW Amana front loader. How to replace Water Level Pressure Switch. Ultimately, I blew through the hose that attaches to the pressure switch. There was initially significant back pressure and then it blew free. Prior to this, I replaced the pressure switch, the main control board, and the pump. All of those were likely unneeded, but unfortunately no web links indicated this particular fix and Amana support was no help. I was very satisfied with the cost of parts on this site and the instructional video links. Just wish I had know to check for clog in the pressure switch tube prior to buying all the parts. Still better than paying for a repair visit though. 13 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
