Samsung Dishwasher Error Code tE2

The tE2 code on a Samsung dishwasher indicates a high temperature heating error. It activates when the thermistor detects a water temperature of 80 degrees Celsius or higher for more than 3 seconds during operation. The dishwasher shuts down to prevent potential damage. The most likely causes are a defective thermistor or a fault in the main PBA.

A reset may temporarily clear the tE2 code, but it will return if the underlying cause is not addressed. If the thermistor is faulty or the main PBA has a defect, the error will reappear once the dishwasher resumes operation and the temperature condition is detected again. A reset is useful for confirming whether the fault is intermittent, but it is not a repair.

Repair costs vary depending on which component has failed. A thermistor replacement is generally the less expensive fix, with parts typically ranging from around $15 to $50 and additional labor costs if a technician is involved. Main PBA replacement is more costly, with parts often ranging from $100 to $250 or more. Getting a diagnosis before purchasing parts can help avoid unnecessary expenses.

Start by checking whether the water temperature is actually elevated or whether the reading is a false signal from the thermistor. Test the thermistor with a multimeter to see if its resistance values match expected ranges for the current temperature. If the thermistor tests as faulty, replace it. If the thermistor reads correctly but the error persists, the main PBA may need inspection or replacement.

It is not recommended to continue using the dishwasher while the tE2 error is active. The code indicates either a real overheating condition or a sensor fault that is preventing the appliance from monitoring water temperature correctly. Running the dishwasher without a functioning temperature control system could lead to further component damage or unsafe operating conditions.
