LG oven error codes
LG washers and dishwashers show short letter codes like OE, IE or UE. LG refrigerators add an Er prefix, such as Er IF or Er FF, ovens show an F and a number such as F9 or F10, and mini-split air conditioners show CH followed by two digits, such as CH05. Most can be cleared by fixing the cause and turning the appliance off and on again.
