Lg Dishwasher Error Codes — Complete Error Code Diagnosis Guide

LG dishwashers use two-letter codes, and eleven are decoded here. IE is a fill timeout and FE is its opposite, an overflow from a stuck inlet valve or a bad level signal. OE is a drain error, AE is a leak the float has caught, and HE and tE are the heater and the sump thermistor that reports on it. LE is the wash motor, nE is the Vario diverter that switches spray-arm feeds, CE is a communication failure between the door display module and the base board, PF is a logged power failure, and bE is the machine objecting to detergent or to not sitting level.

The guides pair the codes that arrive from the same root so a reader does not chase two repairs. tE and HE are the clearest example: scale coating the sump probe insulates it from the water and produces a temperature complaint that looks like a heater fault. nE is worked mechanically, with the spray arms off and the bearings checked for scale, before the diverter motor is condemned. CE starts at the door-edge harness, which cracks where it bends, and bE ends at levelling feet and detergent choice rather than at a part.

AE is the code that ends the diagnostic patience: the float has found water outside the tub, and each further cycle adds to what is already on the floor pan. Line voltage and standing water share this cabinet, so the breaker precedes any work at the sump, the pump gasket or the door seal. Nothing here is gas or refrigerant work, which keeps the boundary electrical. EasyBear services LG dishwashers across Sacramento and the Bay Area.
