What nF means on a Amana washer

The nF error code on an Amana washer indicates a no-fill condition, triggered when the machine detects either a continuous fill lasting 12 minutes or a total cumulative fill time reaching 14 minutes without achieving the required water level. This tells the control board that water is not entering the tub at an adequate rate or volume to satisfy the selected cycle's demand. The washer monitors fill progress through the pressure switch or water level sensor, and when the threshold time limits are exceeded, the control board halts the cycle and displays nF to prevent running the motor without sufficient water.

The fill system involved in this fault includes the household water supply, inlet hoses, inlet valve screens, the water inlet valve assembly itself, and the water pressure switch or level sensor. Any restriction or failure along this path can prevent water from reaching the tub fast enough to satisfy the control board's timing parameters. Low household water pressure is a frequent contributor, as the inlet valve requires adequate pressure to open fully and allow proper flow.

Diagnosis should begin with the No Water Fill troubleshooting section, which systematically checks supply pressure, hose condition, inlet valve screen blockages, inlet valve solenoid function, and the pressure switch circuit. A clogged inlet screen is one of the most common physical causes and is straightforward to inspect. If supply and screens check out, the inlet valve solenoids should be tested for proper electrical resistance, and the pressure switch hose and switch itself should be inspected for blockages, cracks, or electrical faults.

Common causes of nF

  1. 01

    Low or no household water supply pressure

    Wiring / connection

    If the water supply valves behind the washer are not fully open, or if household water pressure is too low, the washer cannot fill within the allowed time. Check that both hot and cold supply valves are fully open and that other faucets in the home have normal pressure.

  2. 02

    Clogged water inlet valve screens

    Wiring / connection

    Fine mesh screens inside the inlet valve ports can accumulate sediment and mineral deposits over time, severely restricting water flow. Disconnect the inlet hoses and inspect the screens visually, cleaning or replacing them if blocked.

  3. 03

    Failed water inlet valve

    Part replacement

    The inlet valve solenoids can fail electrically or the valve body can stick closed, preventing water from entering even when the control board sends the correct signal. The solenoids should be tested for proper resistance; a solenoid reading open or shorted indicates a failed valve requiring replacement.

  4. 04

    Kinked or restricted inlet hoses

    Wiring / connection

    A kinked, pinched, or collapsed inlet hose can severely limit water flow into the machine. Inspect both hot and cold inlet hoses along their entire length for bends, kinks, or damage.

  5. 05

    Faulty water pressure switch or blocked pressure hose

    Part replacement

    The pressure switch monitors water level by sensing air pressure through a small hose connected to the tub. If this hose is cracked, clogged, or disconnected, or if the switch itself has failed, the control board may never receive confirmation that the tub has filled, triggering nF even when water is present.

Frequently asked questions about nF

What does nF mean on a Amana washer?
The nF code means the washer experienced a no-fill condition, specifically that it ran a continuous fill for 12 minutes or reached a total fill time of 14 minutes without detecting enough water in the tub. The washer stops the cycle to protect itself and its components. This code points to a problem somewhere in the water supply or fill system, ranging from simple supply issues to a failed inlet valve.
How do I fix the nF error code on my Amana washer?
Start by confirming that both hot and cold water supply valves are fully open and that household water pressure is adequate. Next, inspect the inlet hoses for kinks and check the mesh screens inside the inlet valve ports for sediment buildup, cleaning them if necessary. If those checks pass, the water inlet valve solenoids and the pressure switch should be tested for proper electrical function, and the pressure switch hose should be checked for cracks or blockages. Replacing a faulty inlet valve or pressure switch will typically resolve the error if the supply side is confirmed good.
Is it safe to continue using my Amana washer when the nF code appears?
The washer halts the cycle when nF appears to prevent running without adequate water, so the machine is protecting itself automatically. You should not attempt to bypass the error and run a load, as operating the motor and components without proper water levels can cause damage to the pump, bearings, and drum seals. Resolve the underlying fill issue before running another cycle.
Will resetting my Amana washer clear the nF error code?
A reset may temporarily clear the displayed code, but if the underlying cause of the no-fill condition has not been corrected, the washer will trigger nF again during the next fill cycle. The code will continue to appear until the root cause, such as a clogged screen, failed inlet valve, or supply pressure problem, is properly diagnosed and repaired.
How much does it cost to repair an Amana washer showing the nF error?
Repair costs vary depending on the cause. If the fix is simply cleaning clogged inlet screens or fully opening a supply valve, there is no parts cost and only your time is involved. A replacement water inlet valve typically costs between $25 and $75 for the part, while a replacement water pressure switch generally runs between $15 and $50. If a technician is needed for diagnosis and installation, labor costs typically add $80 to $150 or more depending on your area.
