The LDT5678ST is an LG top-control dishwasher. Discontinued — LG’s own US product page flags this exact model discontinued (read 24 September 2026); it is out of production but not out of the field, and it is exactly the kind of model that has nowhere else to turn for support. On this platform, the PE fault code is one of the more common reasons it gets a service call.
Service calls on this dishwasher most often trace to one of a short list: the PE, bE or nE fault codes. We confirm which one applies against the model and serial number before ordering a part.
