What to do
- Switch it off
LG gives no home fix for tE, so there's nothing to clean or reset. Turn the dishwasher off with the Power button.
When to call an engineer
Book a repair. LG says a technician needs to check the temperature sensor and its connection.
A repair visit will usually check the sensor's reading with a meter, then its wiring.
Before you book
- Note the model and serial number. They're on a label on the edge of the door or the side of the tub.
- Write down the exact code, and what the appliance was doing when it appeared.
- Check whether it's still under warranty. If it is, the repair may cost you nothing.
