Speed Queen Washer nF: No Water Fill — Supply Not Reaching Tub
The nF code on a Speed Queen washer stands for No Fill — the control board started a fill cycle but did not detect water entering the tub within the allowed time window. On Quantum Touch models (TR7, TC5, FF7), the timer allows approximately 8 minutes for water to reach the minimum level.
Quick Checks
- Both supply valves open: Hot and cold must both be fully open
- Hose kinks: Check behind the machine for kinked supply hoses
- Inlet screens: Disconnect hoses from machine, check mesh screens in inlet ports
- Water pressure: Test each hose into a bucket — need strong flow

Quantum vs Classic Control Differences
Quantum Touch (TR7, FF7): Electronic control with digital display. nF appears on the LED panel. The control monitors fill using a pressure transducer for precise water level measurement.
Classic (TR5, TC5): Mechanical timer control. Does not display nF — instead, the machine simply sits with the timer not advancing (waiting for water). If the timer is stuck in the fill position, check water supply.
Inlet Valve Testing
- Unplug the washer
- Access the valve (rear panel on top-loaders, top panel on front-loaders)
- Disconnect solenoid connectors
- Measure resistance: expect 500-1000 ohms per solenoid
- OL = dead solenoid — replace valve
