An LG dishwasher AE error code means that the dishwasher may be leaking. If you cannot see any signs of a leak, there may be excess water in the base of the dishwasher, usually under the bottom panel where there is a basin and a leak sensor.
Dishwasher leaks or triggering of the leak sensor often occurs because of too much detergent being used, damaged spray arms, a damaged door gasket, or a hose or pump blockage.
The display shows a bE error code when you use dish soap instead of dishwasher detergent in your dishwasher. The dishwasher requires proper leveling to operate correctly. A leveling tool helps you verify the dishwasher base is perfectly level. The dishwasher's leveling legs need adjustment to solve this problem. The bE error code appears when you use the wrong detergent because it creates excessive soap suds in the dishwasher. The Auto cycle of the LG dishwasher requires a bowl with 4-7 ounces of milk on the upper dish rack to remove suds.
The LG dishwasher shows CE error code because of motor defects or improper motor wiring connections. The dishwasher error code will clear after disconnecting power for ten seconds but you should check the motor and wiring harness for proper function. The motor and wiring harness need inspection and either repair or replacement to prevent the error code from reappearing.
See error code AE above.
The FE error code on LG dishwashers appears when the machine detects excessive water accumulation. The FE error code appears most frequently because of three main issues which include a faulty water inlet valve and problems with the float switch and drainage system.
The LG dishwasher HE error code shows that the appliance failed to heat water properly or the water reached temperatures above 149 degrees Fahrenheit. The dishwasher heating element has failed so you need to replace it to resolve the problem.
The LG dishwasher displays IE error code when the water level inside the dishwasher fails to reach the required height during the ten-minute filling process. The error code appears because of insufficient water pressure or incorrect drain hose installation or improper dishwasher leveling.
The LE motor error in LG dishwashers points to a motor malfunction. Check the error code CE for more details.
The LG dishwasher nE error code shows that the motor which operates the spray arms has developed a problem. The nE error code can be resolved by turning off power to the dishwasher for several minutes.
The motor requires multimeter testing to check for failure when the error code persists after power disconnection. Check for loose wiring harnesses and foreign objects that could block the motor before proceeding with motor replacement.
The LG dishwasher display shows OE when it faces issues with draining water. The error code requires you to check for food blockages in the dishwasher base and filter and verify that the drain hose remains untangled and free from blockages and inspect the air gap and drain pump for proper function.
The PF error code on an LG dishwasher appears when the power supply to the appliance gets interrupted. The PF error code emerges from two main causes which include power interruptions and insufficient dedicated 120v 60Hz AC-only 15-amp circuit breaker protection for the dishwasher. The PF error code appears when you power the dishwasher through an extension cord or when the dishwasher lacks proper grounding. Users can resolve the error by pressing any control panel button followed by a 10-second wait for the system to reset. Users should attempt to resolve the issue by unplugging the power supply for several minutes.
The LG dishwasher TE error code shows when water temperature exceeds 194 degrees Fahrenheit or when there is a thermistor malfunction. The thermistor replacement stands as the primary solution to resolve this issue.
