Temperature sensor problem. Here is what it means and how to clear it, easiest fix first.

May need a pro

The control is getting an abnormal reading from the temperature sensor (thermistor), or the water went above about 194°F (90°C). A loose connection or a failed sensor is the usual cause.

Safety first: unplug the dishwasher (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix LG tE

Reset the power
Turn the dishwasher off, then switch off its circuit breaker for about 10 seconds and switch it back on. Power the unit up and start a fresh cycle to see whether the code returns.
Note the code and model number
Write down the exact code, when in the cycle it appeared, and the model and serial numbers from the rating label (usually on the side or top edge of the door or tub). With nothing safe left to check yourself, this lets the technician bring the right part on the first visit.

When to call a technician

If tE comes back after a reset, have a technician inspect the thermistor and its wiring.
