Problem: Hot/cold water supply hoses reversed
How to Fix nF1 Error
- This is an alias for the 4C2 error, indicating the hot and cold water supply hoses are reversed.
- Shut off the water supply faucets.
- Swap the hoses on the back of the washer so the hot hose goes to the hot inlet and the cold hose goes to the cold inlet.
- Tighten the connections and turn the water back on.
Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
