LDNPQ44HS

Configuration and exact-model context

LDNPQ44HS is a 16-place-setting top-control dishwasher with BlastZone bottle-wash jets and AutoVent Dry. The drying feature opens the door during the drying phase; that normal action has to be kept separate from the F37 Auto Open Dry motor fault identified in the manual. The same newer troubleshooting table also distinguishes heated-air temperature sensing from heated-air fan operation, so a drying-related complaint cannot be reduced to one generic message.

Physical fit and installation reading

LG gives LDNPQ44HS a 23 3/4-inch product depth and the same 23 3/4-inch width. These body dimensions are a starting point for a cabinet check; the door, water connection and drain still need space. AutoVent Dry opens the door during drying, so nearby drawers or handles should leave that movement unobstructed. BlastZone jets are intended for bottle washing, and 16 place settings describe overall loading capacity. When an F-series drying alert appears, read its exact characters rather than inferring a fault from normal door movement.

How to read the documented signals

The manual assigns F35 a specific meaning: The heated-air temperature sensor reported a fault. Its first documented response is to arrange service. By comparison, F31 means the heated-air fan 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 F37, LG writes that the auto open dry motor reported a fault; the first listed step is to arrange service. The IE entry instead reports: The dishwasher is not receiving water. Its initial instruction is to open the water supply and check the inlet hose for a kink, blockage, or freezing. The distinction is in the complete displayed signal, rather than a broad symptom description.

Another entry, OE, is explained this way: The dishwasher is not draining. The associated first action is to check the drain hose for blockage, freezing, or kinks. AE has a separate explanation: The dishwasher detected a water leak. For that indication LG starts with an instruction to turn off its water supply and arrange service. The signals concern separate conditions, even though both can interrupt an ordinary cycle.

The LG manual also explains bE: The dishwasher detected too many suds or is not level. It first instructs the owner to use only automatic-dishwasher detergent. For P1, the manual says a downloaded wash cycle is selected; this is a status display; it first instructs the owner to select another cycle if desired. One of these is a status or maintenance state, so their similar-looking labels do not make both faults. The full display string or light pattern remains the most useful detail to record.
