Panasonic Washing Machine H18 error code

Difficulty: Hard · Cost: $80–$250 · Duration: Requires professional service

The H18 error means your Panasonic washing machine detected a problem with the motor thermistor — the temperature sensor that monitors the wash motor to prevent it from overheating. An abnormal reading from this sensor causes the machine to stop the cycle as a safety measure. A technician will need to inspect the motor connections and replace the sensor or motor if needed.

Common causes

Motor thermistor has malfunctioned or failed
Motor connections are loose or damaged
Motor has overheated and the thermistor is correctly detecting an out-of-range temperature
Motor itself has developed a fault

How to fix it

1

Unplug the machine and allow it to cool down for at least 30 minutes
2

Plug it back in and try restarting the cycle to see if the error clears
3

If H18 returns after cooling contact a qualified technician to inspect the motor connections and thermistor
