DISPLAYHE
The water is not heated correctly or becomes too hot.
LG assigns HE to the heating system. A repair inspection is needed if the code remains after a controlled restart.
Switch the appliance off in a controlled way, safely disconnect power, wait at least 30 seconds and restart once. Contact manufacturer service if the code remains.
Error codes can differ by model and series. Also check the exact model number and the matching LG manual.
