What I found
The washer in the shared laundry room was out of service with an nFLo error on the display. The report also mentioned that it could stop with 13 minutes left in a towel load.
The fill side of the washer needed a new mixing valve. The replacement specified for this machine was Alliance Laundry Systems 205547P, a dual 120V water mixing valve.
How I replaced the valve
I shut off the water supply, disconnected the fill hoses and opened the washer cabinet. After removing the wire connectors and hoses from the old valve, I took it out and compared it with the replacement.
I installed the 205547P valve, reconnected the wiring and hoses, and attached the hot and cold supply lines to the corresponding inlets. With the water back on, I checked the hose and valve connections before closing the machine and returning it to service.
Result
The new mixing valve and fill connections were installed and the washer was returned to service in the shared laundry room. The total was $352, with a 6-month warranty on parts and labor.
Part replaced: Alliance Laundry Systems dual water mixing valve 205547P.
