My LG washer is displaying the te error code and it keeps shutting down. What do i do?

Hi from retired Englishman in SW France,
'te' for an LG normally means 'heating error' (Temperature).
(It might be worthwhile trying this but sorry, no promises 1)
This could be that the element is coated in calcium. I suggest you run the contents of a couple of sachets of proprietary limescale removing powder/fluid through it. The most efficient way is to put the contents in an empty washer and pour a kettle or two of boiling water into the drum then leave overnight. In the morning run just a spin; the water mix will then go through the drain filter and drain motor impeller blades, doing absolutely NO harm whatsoever, in fact some good!
You could also consider repeating the action ;-0)

If this has assisted you please consider a 4 thumbs up for the rating.
Thanks and good luck!

Try to unplug your unit 15 minutes ..if show up again have bad Thermistor or heating element ... the best replaced both.. two thermistor on unit.. ..1 is located in bottom of tub other 1 is on steamer
