- Water inlet valve and fill
The LDNPQ445S is a top control dishwasher from LG with FlushFit design, built-in leak detection, high-pressure jets, a third rack, and a floor status indicator that shows when a cycle is complete. It is an under-counter unit and, because of the FlushFit face, it sits close to the cabinet line.
The floor indicator is a feature owners notice when it stops working, so we check its wiring and lens early. Then we go through the third rack rails, the jet nozzles, and the filter. For a leak alert, we check the base pan, door seal, and hoses. If the dishwasher fills slowly or leaves water behind, we move to the inlet valve and drain pump.
The label gives us the model and serial, and we use them to pick the right part. You get a written price first, and a 30-day workmanship warranty covers the repair.

Error codes this model can show
The floor light on my LDNPQ445S does not show. Is that a big repair?
Often it is not. We check the indicator, its wiring, and its connection to the board. If a part is needed, we quote it in writing before replacing it.
What does the third rack need in service?
Smooth rails and secure clips. We look for wear, bent pieces, and debris in the track, and we order matching parts after confirming the model.
Why does the dishwasher show a leak alert after I move it?
Moving it can shift hoses or leave water in the base. We dry the pan, check the connections, and then test the sensor if the alert stays on.
