LUDP8997SN
LG SIGNATURE LUDP8997SN Repair
Most common issues on this model
- Third rack rails and height adjuster when the rack sticks or tilts
- Spray arms and filter for gritty or filmy dishes
- Wi-Fi connection and panel response when the cycle will not start
- Drain pump and hose for water left in the tub
- Inlet valve and door seal for slow fills or leaks
The LUDP8997SN is a top-control dishwasher from the LG SIGNATURE line with the QuadWash System, EasyRack Plus, a height-adjustable third rack and ThinQ connectivity. It is a current model, so most of the ones we see are in newer or remodeled kitchens.
The moving rack system matters for service. Third rack rails and the height adjuster can bind if a dish falls behind them, and a misaligned rack can also block a spray arm. We check rack travel first, then the arms and filter when owners report poor cleaning.
Connected features add a network step: if the unit ignores commands from the phone, we confirm the panel works on its own before looking at the board. We read the model and serial from the label before ordering parts and quote in writing first.

Error codes this model can show
What goes wrong with a third rack that sticks?
Usually a wheel off its track, a bent rail or something wedged behind it. We inspect the rails and adjuster, which often means only a small part and a short visit.
The dishwasher does not respond to the app. Should I call?
Try the panel directly. If it runs from the panel, the problem is the network link, and a reset may help. If not, we test the latch, the board feed and the display.
Do you check the spray arms on a QuadWash dishwasher?
Yes. With several arms, a clogged port reduces coverage fast. We remove each one, flush it, check the filter and confirm the circulation pump is delivering flow.
