Kenmore Washer Error Code nH

The nH code means the washer did not detect adequate hot water at the hot water inlet during the Install Cycle. It can indicate that no water is reaching the machine from the hot supply, or that cold water is being sensed on the hot inlet because the hoses are connected in reverse. The washer uses this Install Cycle check to verify correct plumbing before entering normal operation.

A simple power reset alone is unlikely to permanently resolve the nH code because the error is tied to a specific Install Cycle plumbing check. The code will return if the underlying issue, such as reversed hoses or insufficient hot water temperature, is not corrected. The proper fix is to address the supply problem and then complete the Install Cycle successfully.

If the fix is simply reconnecting the inlet hoses correctly or adjusting the water heater temperature, the repair costs nothing beyond your time. If a clogged inlet screen is the culprit, cleaning it is also a no-cost repair. If the hot water inlet valve has failed and requires replacement, expect to pay somewhere in the range of $40 to $120 for the part plus labor if you hire a technician.

Start by confirming that the hot water hose is connected to the hot water faucet and the cold water hose is connected to the cold water faucet. Then check that both supply valves are fully open and that the hoses are not kinked. Measure the hot water temperature at a nearby sink faucet to confirm it is at least 120°F (49°C). After correcting any issues, rerun the Install Cycle to clear the code.

The nH code appears during the Install Cycle, which is a pre-operation verification step, so the washer is flagging the issue before normal wash cycles begin. Running laundry with reversed hoses is not dangerous, but it will result in cold water being used for hot water cycles and hot water for cold cycles, which can damage certain fabrics and reduce wash performance. It is best to resolve the hose connections before proceeding.
