What the tE (High temp) error code actually means

Your Samsung dishwasher detected that the water inside got too hot, above what it considers safe for normal operation. This could be because your home's hot water is set too high, or because the temperature sensor inside the dishwasher is faulty and giving a bad reading. The dishwasher stopped running to protect itself until the issue is identified and resolved.

Questions people ask about tE (High temp)

What does tE (High temp) mean on a Samsung dishwasher?
The tE code means the dishwasher's thermistor detected a temperature of 80°C or higher sustained for more than 3 seconds. The dishwasher shuts down to prevent damage when this threshold is exceeded. The fault can be caused by an overly hot water supply, a defective thermistor, or a faulty main control board.
Is it safe to use my Samsung dishwasher while the tE code is displayed?
No, you should not continue running the dishwasher while the tE error is active. The code indicates the control board has detected a potentially unsafe operating temperature, and the appliance has halted to protect components and contents. Continued operation without resolving the fault could lead to further damage.
How much does it cost to repair the tE error on a Samsung dishwasher?
Repair costs depend on the root cause. Adjusting a water heater thermostat costs nothing. Replacing a thermistor is generally inexpensive, with parts typically ranging from $15 to $50 and labor adding $75 to $150 if a technician is needed. A Main PBA replacement is more costly, with parts often ranging from $100 to $300 plus labor.
How do I fix the tE error on my Samsung dishwasher?
Start by checking the temperature of your home's hot water supply, as water arriving too hot can legitimately trigger this code. If supply temperatures are normal, the thermistor should be tested and replaced if it is producing inaccurate readings. If the thermistor checks out, the Main PBA may need to be inspected or replaced by a qualified technician.
Will resetting my Samsung dishwasher clear the tE error code?
A reset may temporarily clear the tE code, but if the underlying cause is not resolved, the error will return once the dishwasher runs and the fault condition recurs. Resetting can be useful to confirm whether the fault is intermittent, but it is not a fix for a defective thermistor, an overheating water supply, or a faulty control board.
