What error code nF means on a Kenmore 402 model front-load washer

This is a water fill code. Codes and wording can vary by model, so check your owner's manual for your model number.

How to fix Kenmore 402 model front-load washer error code nF (safe owner checks)

Safety first: disconnect power before you remove any panel or reach into the sump or drum. Do not touch wiring, the control board or the motor. If you see water near electrical parts, stop and call a technician. These steps are based on the Kenmore 402 model front-load washer error-code chart (via Sears PartsDirect) [1], rewritten for clarity.

Write down the code and model number. Note exactly what the display shows (nF) and copy the full model number from the rating label, so you can confirm this chart applies to your 402 model front-load washer and order the right parts.
Open the water supply. Check the water supply faucets behind the washer to make sure that they are fully open.
Check the fill hoses. Check the water fill lines for kinks or freezing (in the winter).
Check the water inlet fill. Check the water inlet fill valves.
Do a power reset. Unplug the appliance or switch off its breaker for one minute, then restore power and try again. If the code clears and stays away, it may have been a one-off fault.
Test and decide. Run a short cycle or restart and watch the display. If nF comes back after these checks, stop using the washer for this function and call a technician, because the remaining causes need meters or part replacement.

The first and last steps (and the power reset) are general owner checks added by ErrorCodePro; the rest follow the Kenmore 402 model front-load washer error-code chart published by Sears PartsDirect, rewritten for safe owner use.
