LG dishwasher error codes at a glance
LG dishwasher error codes at a glance: these are not manufacturer-name substitutions. Every LG dishwasher record maps a real displayed code to its documented meaning, applicable checks and stop condition.
LG dishwashers report problems with codes such as IE for water inlet, OE for drain, FE for overfill and LE for the motor. For IE check that the water supply tap is open and the inlet screen is clear; for OE clean the filter and check the drain hose and air gap; for FE the water level is too high, which can be an inlet valve or sensor problem that needs service.
LG dishwasher FE code: the dishwasher detected too much water
FE means the dishwasher detected too much water. Cancel the cycle and close the supply valve if water keeps entering.

Open recordTroubleshooting an LG dishwasher
Run the Machine Clean cycle with a cleaner occasionally, and load so spray arms can turn freely. If a code stays after power cycling for a minute, note it and call LG service with the model number from the door edge or tub label.
LG dishwashers use codes such as IE for water not entering, OE for water not draining, FE for overfill and LE for a motor fault, and some models show a water-leak or a heater code. Overfilling is serious: turn the unit off, shut off the water and look for a stuck inlet valve or a float problem before running it again.
Clean the filter, check the spray arms spin freely, run the hot tap before starting and use the detergent and rinse aid the manual names. Codes that point to the motor, the heater, the inlet valve or the board need a technician.
LG's QuadWash dishwashers have four spray arms, and a blocked arm or a clogged filter is the first thing to check when dishes stay dirty. LG codes such as IE, OE and FE relate to water in, water out and overfill, so note the code and then check the supply, the drain and the inlet valve. Do not run the machine again after FE until the water has been checked.
LG dishwashers use a heating element and a pump that circulates water through jets, and several codes concern the temperature and the water level. If the dishwasher fills but does not heat, it can show a heating code and give cold, wet dishes. If it shows an inlet code, check the supply valve and the filter screen on the inlet. After any repair, run an empty cycle with a dishwasher cleaner to clear residue, and check that no code returns.
What does the FE code on an LG dishwasher mean?
An overfill: too much water is in the tub, so power it off and call service if it returns after a reset.
What should I do if my LG dishwasher shows FE?
Turn it off, shut off the water and check for standing water. A stuck inlet valve or float is the usual cause, so call for service if it returns.
How do I clean the filter on an LG dishwasher?
Twist out the filter in the tub, rinse the mesh and the cylinder under running water and refit it until it clicks.
Why are my dishes cold and wet?
The heater may have failed or the cycle may not have reached temperature.
