Plain language
What thiscode means
Heating failure.
HE on a Kenmore dishwasher is a heating failure. The manual covers it for Kenmore dishwashers with model numbers beginning 722.146.
When the code appears
The code shows when the water is not heating, or when the thermistor (temperature sensor) reads water hotter than 194 degrees. The first job is to work out which situation you have.
If the water in the tub is extremely hot
Measure the water with an accurate thermometer. A reading near 190 degrees suggests the electronic control board needs replacing, since a stuck heater relay on the board is keeping the heating element on. Unplug the dishwasher before the board is replaced.
If the water does not seem overheated
The likely story is that the heating element was not heating. Unplug the dishwasher and look at the wire harness connections on the heating element and on the pressure switch, which senses water flow to the heater and shuts the heater off if flow is too low. Reconnect loose wires.
After that the work belongs to a technician: testing the heating element and its thermistor with a meter, then live voltage checks to see whether the pressure switch or the control board is stopping the heat.
