Common LG Dishwasher Problems and Error Codes
LG dishwashers share some error codes with LG washers but have fault categories specific to dishwashers:
OE — Drain Error: The LG dishwasher cannot pump water out within the cycle time. Check the sink drain first — a blocked kitchen sink drain is often the actual cause. If the sink drains normally, check the dishwasher drain hose for kinks. A failed drain pump is the third most common cause.
LE — Motor Locked: The wash motor has stalled or seized. Causes include a foreign object caught in the spray arm or pump impeller, or a failing motor bearing.
FE — Overfill: Water is overfilling the dishwasher. The float switch may be stuck down or the water inlet valve is failing to close. FE requires immediate attention to avoid water on the kitchen floor.
tE — Temperature Sensor: The heating element or NTC temperature sensor has failed. Dishes will come out wet and cold rather than dry and sanitized. tE is common in LG dishwashers that run frequently in hard-water areas like Edmonton — calcium deposits on the heating element cause premature failure.
CL — Child Lock Active: This is a user setting, not a fault. Press and hold the child lock button (varies by model) for 3 seconds to deactivate.

LG Dishwasher Models We Service in Edmonton
We service all LG dishwasher models sold in Edmonton, including the LDF5545 and LDF5678 standard series, the LDFN4542 and LDFC2523 front-control series, and the LDT5678 and LDTS5552 top-control series. LG QuadWash models — with four spray arms rather than two — have a more complex wash pump assembly that requires specific knowledge to disassemble and inspect. LG ThinQ dishwashers can send error codes directly to the LG app, but hardware diagnosis still requires a technician.
Why LG Dishwashers Need Specialized Repair
LG dishwashers use direct drive wash motors without a belt, similar in concept to LG washer technology. The QuadWash spray arm system uses a multi-arm pump that distributes water in multiple directions simultaneously. When the QuadWash motor fails, it typically fails in a way that affects all four arms — not just one. LG NeveRust stainless steel tubs also have a specific interior coating; cleaning agents containing bleach or citric acid at high concentrations can damage this coating, causing the tub to appear stained after repair. We advise customers on proper LG dishwasher cleaning during service visits.
