Daewoo Washer Error Code TE

The TE error code on a Daewoo washer indicates a fault within the water temperature monitoring and heating system. Specifically, it triggers under three conditions: the water temperature exceeds 45°C during the wool wash cycle, the heating element fails to activate when it should, or the heater activates while the drum contains no water. The primary sensor responsible for detecting and reporting water temperature is the thermistor, a resistive component whose electrical resistance changes predictably with temperature. When this sensor fails or provides readings outside expected parameters, the control board interprets the data as a thermal fault and halts the cycle to prevent damage.

The thermistor is the first component to investigate because it is the most common point of failure in this circuit. A failed thermistor can report falsely high temperatures, causing the TE code to appear even when actual water temperature is normal. It can also fail to detect temperature at all, which the control board treats as a heating fault. Beyond the thermistor, the heating element itself may be defective, either failing to generate heat or operating erratically. A dry-fire condition, where the heater runs without sufficient water present, can damage both the element and the surrounding components if left uncorrected.

Diagnosis should begin with the thermistor as indicated by the recommended first step. Testing the thermistor with a multimeter will reveal whether its resistance values correspond correctly to the current water temperature. If the thermistor checks out, attention should shift to the heating element for continuity and resistance testing, and then to the water level sensor or pressure switch, which signals the control board about drum water presence before allowing the heater to activate.
