LDNTH753S
LG LDNTH753S FlushFit Dishwasher Repair
Most common issues on this model
- Third rack height adjuster
- Heated drying and the AutoVent opening
- High-pressure jet nozzles
- Drain pump and filter
- Water inlet valve and fill
The LDNTH753S is an LG top control dishwasher with FlushFit design, a one-hour wash and dry cycle, and a height-adjustable third rack. LG also lists high-pressure jets and Dynamic Heat Dry with AutoVent Dry. A second finish shares this base number. It is built for a standard under-counter opening.
Our first checks follow the features. The third rack should adjust and glide, so we test the height mechanism and rails. For slow drying we test the heater and AutoVent. For weak cleaning we clear the nozzles and check the filter, fill, and drain. FlushFit units also need correct clearance at the cabinet fronts, so we confirm the door swings freely.
Reading the model and serial from the label comes before any parts order. You receive a written price in advance, and our repairs carry a 30-day workmanship warranty.

Error codes this model can show
The third rack on my LDNTH753S will not adjust. What is wrong?
The height mechanism may be bent, worn, or blocked by debris. We inspect the rails, clips, and adjuster, then quote the matching part after confirming the model.
Why do dishes stay damp on the one-hour cycle?
Short cycles lean on heat and venting. We check the heating element and the AutoVent mechanism, and we make sure items on the rack are not blocking the vent path.
Can cabinet clearance affect the door?
Yes. A FlushFit door can drag if the unit is slightly out of level or tight to the cabinets. We check level and clearance as part of the visit.
