   Step 1: Reset the Dishwasher

   First, try resetting your LG dishwasher by unplugging it from the power outlet for 30 seconds. This will reset the control panel and may resolve the issue. Plug the dishwasher back in and check if the error code tE is still displayed. If the error code persists, proceed to the next step.

   Step 2: Check the Thermistor

   Locate the thermistor, which is usually located near the heating element. Use a multimeter to measure the resistance of the thermistor. A normal reading for the thermistor should be between 10 kΩ and 20 kΩ. If the reading is outside this range or if the thermistor is damaged, replace it with a new one.

   💡 Pro Tip: When measuring the resistance of the thermistor, make sure to use a multimeter with a high impedance setting to avoid damaging the thermistor.
