Samsung Dishwasher Error Code tE

The tE code indicates a thermistor error, meaning the water temperature sensor is reporting a voltage outside the acceptable range (at or below approximately 0.09V or at or above approximately 4.5V), or water temperature is not rising above 5 degrees Celsius within 30 seconds during heater operation. The dishwasher halts the cycle when this condition is detected. The thermistor and its wiring connections are the primary components to inspect.

No, you should not continue running the dishwasher while the tE error is active. The code indicates the control board cannot verify water temperature accurately, which means the dishwasher may run without proper heating or may not complete the cycle safely. Continuing to operate it in this condition could result in poor wash results or potential component stress.

Repair costs depend on the cause. If the fix is a reseated connector, a service call fee may be the only cost, typically in the range of $75 to $150. Replacing a thermistor is generally an inexpensive part, so total repair costs including labor are often in the $100 to $250 range. If the heating element or control board is at fault, costs can rise to the $200 to $450 range or higher depending on parts and labor rates in your area.

A homeowner or DIYer with basic appliance repair skills can start by checking the thermistor connector for looseness or corrosion, as a disconnected connector is one of the most common causes. If the connector is secure, testing or replacing the thermistor requires more comfort with electrical components and multimeter use. A licensed technician is recommended if you are not comfortable working inside the appliance.

A power reset may temporarily clear the error display, but the tE code will return if the underlying fault is not corrected. Resetting does not repair a failed thermistor, damaged wiring, or loose connector. The root cause must be diagnosed and addressed before the error will stay cleared.
