Samsung Dishwasher Error Code HE

The HE code means the dishwasher experienced a heater error. Specifically, the water temperature did not reach the required level within 60 minutes during a heating step. This points to a problem with the heating element, the temperature sensor, the water level, or the low-level protection device. The machine stops the cycle automatically when this condition is detected.

It is not recommended to continue running the dishwasher while the HE code is active. The machine will not complete cycles properly, and dishes will not be sanitized at the correct temperature. More importantly, a fault in the heating circuit or water level system could pose a risk if the heater runs without adequate water present. Address the underlying cause before resuming normal use.

A reset may temporarily clear the HE code from the display, but if the underlying problem is not resolved, the error will return once the dishwasher attempts another heating cycle. You can try a reset by powering the machine off at the circuit breaker for a few minutes, then restarting. If the code comes back, the heating element, temperature sensor, water fill system, or low-level protection device needs to be properly diagnosed and repaired.

Some causes of the HE error are DIY-friendly, such as reseating a loose heater connector or checking that the dishwasher is filling with enough water. Testing the heating element for continuity or replacing the thermistor requires basic comfort with a multimeter and appliance disassembly. Replacing the low-level protection device or heating element involves working with internal wiring, so those repairs are best approached carefully or left to a technician if you are not confident.

Repair costs vary depending on the failed component. Replacing a heating element typically runs in the range of $50 to $200 for parts, with additional labor costs if a technician is hired. A thermistor or temperature sensor is usually less expensive, often in the $15 to $60 range for the part. A service call with diagnosis and labor can add $80 to $150 or more depending on your location and the repair provider.
