What to do when the dishwasher shows HE, HE1, HE2, or HE3 error?

HE, HE1, HE2, and HE3 codes are all related to heater error. These codes occur when the temperature inside the dishwasher is detected to be abnormal in status and value.

The errors can indicate issues like no heating of water or the water is heating up at a very high temperature.

Please do the following when you encounter (HE, HE1, HE2, HE3) error codes in the dishwasher:

1. Most of these errors are due to the high temperature on the thermostat. You may need to let it cool down by not using it for half a day and check again. 
2. IF the dishwasher really stopped heating up and not able to heat up the water, the thermostat could be damaged and requires service.
