What is the error code nF on Speed Queen?

The nF error code on a Speed Queen appliance, often displayed as "Er nF" on the digital display, indicates a water fill issue with the washer.

Understanding the nF Error Code

When your Speed Queen washer displays the nF error, it means the machine has failed to fill to the proper water level. This error is triggered if the washer senses little or no change in the water level within approximately 5 minutes of starting its current fill cycle. Essentially, the machine isn't detecting enough water entering the tub to proceed with the wash cycle.

Common Causes of the nF Error

Several factors can lead to a Speed Queen washer displaying the nF error:

Closed Water Faucets: The most common reason is that the hot and/or cold water supply faucets connected to the washer are not fully turned on.
Restricted Water Flow: Issues like kinked hoses, clogged inlet screens on the water valves, or low household water pressure can also prevent adequate water from entering the machine.
Inlet Valve Malfunction: A faulty water inlet valve might not open correctly to allow water into the tub.
Water Level Sensor Issues: Though less common, a malfunctioning water level sensor might incorrectly report that the tub isn't filling.

How to Resolve the nF Error Code

Addressing the nF error is usually straightforward and can often be resolved with a few simple checks:

Check Water Supply Faucets:
- Locate the hot and cold water faucets connected to the back of your Speed Queen washer.
- Ensure both faucets are fully turned on. Even if one is partially closed, it can significantly impact water flow.
Inspect Water Hoses:
- Verify that the hot and cold water inlet hoses are not kinked or crimped, which can restrict water flow.
- Ensure the hoses are securely attached to both the washer and the wall faucets.
Reset the Machine:
- To clear the nF code from the digital display and reset the washer's internal sensors, unplug the machine from the electrical outlet.
- Wait for approximately 15 seconds.
- Plug the machine back in.
- Attempt to start a new wash cycle to see if the error has cleared.

If, after performing these steps, the nF error persists, it may indicate a more complex issue such as a faulty water inlet valve or pressure switch, which might require professional assistance.
