Samsung Dishwasher Error Code tE (High Temp Heating)

The tE error code means the dishwasher's thermistor has detected a water temperature of 80°C (176°F) or higher for more than 3 seconds. The machine shuts down the cycle automatically to prevent damage. This can be caused by an overly hot water supply, a faulty thermistor, a malfunctioning heating element, or a defective control board.

A reset may temporarily clear the code and allow the dishwasher to restart, but the error will return if the underlying cause is not corrected. If the water supply temperature is too high or a component is faulty, the thermistor will again detect 80°C or above and halt the cycle. A reset alone is not a fix.

Repair costs depend on the root cause. If the issue is only the water heater thermostat setting, there is no parts cost. Thermistor replacement typically falls in the range of $20 to $80 for the part, while a heating element can cost between $30 and $120. Control board replacement is the most expensive scenario, generally ranging from $100 to $300 or more, not including labor.

Start by checking whether your home's water heater is set too high, since incoming water above 80°C will trigger this code without any component failure. If the supply temperature is normal, inspect and test the thermistor and heating element for faults. Replacing the defective component should clear the error.

No, you should not continue operating the dishwasher until the cause is identified and resolved. Water at 80°C or above can damage plastic internal components, warp dish racks, and potentially create a burn hazard if the door is opened during operation. The error exists specifically to prevent continued use under unsafe conditions.
