LG washing machine TE error code
What TE means on an LG washing machine
Temperature sensor or heater circuit fault.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
On an LG washing machine, the TE code means the machine has found a fault with its temperature sensor or its heater circuit. In everyday terms, it cannot heat the water or keep track of how warm the water is, so it may stop partway through a wash or refuse to start a cycle.
One thing engineers sometimes find is a torn or worn door seal. Water escapes through the damaged seal and drips onto the heater, which sits underneath. Over time the heater rusts and stops working properly, and the temperature sensor that is fitted with it can no longer do its job. If your door seal is split or has a hole in it, that is worth mentioning when you book.
An engineer will usually run a wash to look for leaks, inspect the door seal and check the heater and its wiring. The usual repair is a new door seal together with a new heater, which comes with its temperature sensor already fitted. These parts often have to be ordered, so the repair is commonly finished at a second visit, followed by a test wash to make sure everything works as it should.

Before you check anything yourself
- Switch the washing machine off and unplug it, or turn it off at the isolator switch, before you touch anything. Our guide to safely isolating an appliance walks you through it.
- An error code tells you where to look, not that it's safe to take the washing machine apart. Don't remove panels or covers to get at the parts it points to: that's an engineer's job.
- If it involves the mains supply, sealed parts, or you're not confident at any point, stop and book a qualified engineer rather than risk injury or further damage.
