As a front-control dishwasher, the LDFN343LS shares its core mechanism with the rest of LG’s dishwasher lineup. On this platform, the PE fault code is one of the more common reasons it gets a service call. LG’s own US product page still carries this model with an active status flag, read 24 September 2026.
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.
