Kenmore Dishwasher Error Code HE

The HE code on a Kenmore dishwasher signals a heater error. It means the control board detected that the water either failed to reach the required temperature during the wash or rinse cycle, or that the water temperature exceeded the safe limit of 194°F. The dishwasher stops the cycle automatically when this code appears to prevent damage or unsafe conditions.

You should not continue running the dishwasher while the HE error is active. The code can indicate either a failure to heat water, which means dishes will not be properly cleaned or sanitized, or an overheating condition above 194°F, which poses a more serious risk. Stop using the appliance until the fault is diagnosed and resolved.

A reset may temporarily clear the HE code, but if the underlying problem with the thermistor, heating element, or wiring has not been fixed, the error will return as soon as the dishwasher attempts another cycle. Resetting is a useful first step to confirm whether the fault is intermittent or persistent, but it is not a substitute for diagnosing and repairing the root cause.

Some causes of the HE error are DIY-friendly, such as checking and reseating wiring connections or confirming that the hot water supply is reaching the dishwasher at an adequate temperature. Testing and replacing the thermistor or heating element requires a multimeter and basic appliance repair skills. If you are not comfortable working with electrical components inside the appliance, a qualified technician should handle the repair.

Repair costs depend on which component has failed. A replacement thermistor typically runs in the range of $15 to $40 for the part, while a new heating element generally costs between $20 and $60. If you hire a technician, labor charges will add to the total, often bringing the full repair cost to somewhere between $100 and $250 depending on your location and the parts needed.
