What's Happening

The temperature sensor (thermistor) has failed or its connections are loose. The dishwasher may not heat water properly, leaving dishes poorly cleaned. A loose wire harness connection is sometimes the cause.

How to Fix It

This error requires a service technician. The thermistor and its wiring need to be inspected. A loose harness connection is the best-case scenario. If the sensor has failed, it needs replacement.

Frequently Asked Questions
What does tE mean on an LG dishwasher?
tE indicates the temperature sensor has failed or has a loose connection. The dishwasher can't properly monitor water temperature.
Can I fix an LG dishwasher tE error myself?
It's possible if it's just a loose wire connection, but diagnosing and accessing the thermistor requires opening the dishwasher. Most people need a technician for this.
Will my LG dishwasher still clean dishes with a tE error?
It may run, but water won't be heated to the correct temperature, resulting in poor cleaning and sanitization. Get it fixed for proper performance.
