The LDNTH862S is a top control dishwasher from LG with FlushFit design and a one-hour wash and dry cycle. LG lists a height-adjustable third rack, high-pressure jets, and Dynamic Heat Dry with AutoVent Dry. It is a built-in unit that slides into a standard under-counter space beside the sink.
On a dishwasher that dries as well as washes in an hour, drying is where we spend time. We test the heating element and watch the AutoVent mechanism open and close. If a cycle ends with water pooled on top of cups, we also check that the rack is level and that nothing blocks the vent. Cleaning problems go to the nozzles, filter, and fill, and the third rack rails get a test for smooth travel.
We read the model and serial from the label before ordering any part. You get a written price first, and a 30-day workmanship warranty covers the repair.

Error codes this model can show
Why does water pool on top of cups in my LDNTH862S?
Water pools when the tilt of the cup, the heat, or the vent does not work together. We check the heater and the AutoVent mechanism, and we look at how the load sits on the rack.
Will you look at the third rack too?
Yes. We check the rails, clips, and height adjuster while we are in the unit, and we quote any worn part before replacing it. The third rack sees daily use, so wear there is worth catching early.
Is a short cycle harder on a dishwasher?
It asks more of the heater, pump, and jets in less time. If any of them is weak, results suffer first on a short cycle, so we test each one.
