LDT7797BD

Configuration and exact-model context

LDT7797BD is a black-stainless top-control dishwasher with QuadWash and a height-adjustable third rack. The rack changes how small items can be arranged, while the wash codes speak to water, suds, heat and internal operation. In particular, bE can involve suds or levelling; FE indicates excess water, a different event. A user seeing foam should still record the precise display rather than guessing that every moisture-related symptom is a leak.

Physical fit and installation reading

For LDT7797BD, LG states a 23 3/4-inch width and 24 5/8-inch product depth. The adjustable third rack adds flexibility inside the machine, which is useful only if the kitchen leaves room to open the door and reach the racks. QuadWash describes spray coverage during a cycle, not the size of the cabinet opening. The top controls may be less visible with the door closed than front controls, so note the precise panel indication when investigating an interrupted wash. Use the manual drawing for the remaining plumbing and electrical clearances and the exact model number for finish-specific parts.

How to read the documented signals

The manual assigns bE a specific meaning: The dishwasher detected too many suds or is not level. Its first documented response is to use only automatic-dishwasher detergent. By comparison, FE means too much water entered the dishwasher. 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 AE, LG writes that the dishwasher detected a water leak; the first listed step is to turn off its water supply and 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, tE, is explained this way: The water temperature sensor reported a fault. The associated first action is to arrange service. IE has a separate explanation: The dishwasher is not receiving water. For that indication LG starts with an instruction to open the water supply and check the inlet hose for a kink, blockage, or freezing. The signals concern separate conditions, even though both can interrupt an ordinary cycle.

The LG manual also explains OE: The dishwasher is not draining. It first instructs the owner to check the drain hose for blockage, freezing, or kinks. For P3, 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.
