Daewoo Washer Error Code HE

The HE error code on a Daewoo washer indicates a fault within the wash heating system. Specifically, the code is triggered when the control board detects a problem with the wash thermistor, a failed or disconnected connector contact in the heating circuit, or a condition where the heater element is operating without sufficient water in the drum. The thermistor is responsible for monitoring water temperature during wash cycles, and when it reads a value outside the expected resistance range or loses contact entirely, the board interprets this as a heating system failure and halts normal operation.

The most common hardware cause is a degraded or failed thermistor, which can drift out of its correct resistance range over time due to heat exposure and wear. Loose, corroded, or disconnected connector contacts between the thermistor or heater and the control board are equally common and are the first hardware point to inspect. A disconnected contact will produce an open circuit reading, preventing any valid temperature signal from reaching the board.

The third scenario, the heater running dry without water in the drum, is a safety-related fault. If the water inlet system fails to fill the drum to the correct level before the heating phase begins, the element can overheat and the control board detects this abnormal condition. Checking both the physical connector contacts and the current water level in the drum are the recommended first diagnostic steps before moving on to component-level testing of the thermistor and heater.
