Plain language
What this code means
E4 is a steam heater fault on the LG Styler.
A steam heater problem is what E4 reports on an LG Styler. Among the Styler codes in LG’s help list, it appears as “Steam Heater Error”.
E4 versus E1
E1 is about the steam heater’s sensor, while E4 names the heater. Seeing one or the other tells you which part of the steam system the Styler is complaining about. See E1 for the sensor version.
Next step from the manual
Contact customer support. The list adds that the unit will require a repair service, and no checks for owners are included.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
