Before you book,
in this order.
Each step comes from LG's own guidance for tE on its dishwashers. Follow it to the end: the last card says whether this is a visit.
Turn the machine off and cut the breaker for a short while, then try one cycle.
Leave the door closed while it runs so the reading is not disturbed.
If tE persists, book a visit to have the thermistor and its wiring tested.
What not to do
Do not read tE as a heating element failure. LG points at the temperature sensor, and the element may be fine.
