LDF5545BB

Configuration and exact-model context

LDF5545BB is a black, front-control, 15-place-setting dishwasher with QuadWash and NFC Tag On. NFC Tag On is an interaction feature; it does not change the meaning of a wash-motor, vario-motor or water-leak warning on the appliance. Older and newer LG products can use similar short codes, so this exact model’s support and manual links should be preferred over a generic code-search result.

Physical fit and installation reading

LDF5545BB is a black front-control dishwasher with a documented width of 23 3/4 inches and product depth of 24 5/8 inches. When planning a replacement, use those measurements instead of assuming every appliance sold as 24-inch has identical depth. Leave usable space for the door to open and for large pieces to enter the lower rack. NFC Tag On is an interaction feature, while QuadWash describes the spray system; neither name specifies a different cabinet cutout. If a code appears after fitting, compare the exact display with the LG manual rather than treating the exterior finish as a diagnostic clue.

How to read the documented signals

The manual assigns LE a specific meaning: The wash motor reported a fault. Its first documented response is to arrange service. By comparison, NE means the vario motor reported a fault. LG initially directs the owner to arrange service. The two displays point to different checks even if the cycle stops in a similar way.

For FE, LG writes that too much water entered the dishwasher; the first listed step is to arrange service. The HE entry instead reports: The heater circuit reported a fault. Its initial instruction is to arrange service. The distinction is in the complete displayed signal, rather than a broad symptom description.

Another entry, P4, is explained this way: A downloaded wash cycle is selected; this is a status display. The associated first action is to select another cycle if desired. CL has a separate explanation: Control Lock is active; this is a status display. For that indication LG starts with an instruction to use the model-specific button combination in the manual to turn off control lock. The signals concern separate conditions, even though both can interrupt an ordinary cycle.

The LG manual also explains AE: The dishwasher detected a water leak. It first instructs the owner to turn off its water supply and arrange service. For OE, the manual says the dishwasher is not draining; it first instructs the owner to check the drain hose for blockage, freezing, or kinks. They identify different conditions even if both appear during the same general phase of use. The full display string or light pattern remains the most useful detail to record.
