Customer Ratings & Reviews

Hi there! We understand your inquiry about your LG 24” Top Control Smart Built-In Dishwasher (Model LDTH7972D) and appreciate you letting us know how persistent rack rail issues have impacted your experience. Stability of your third rack is key for loading flexibility, so let’s try a quick troubleshooting step to ensure the rail and rollers are properly seated:

Troubleshooting Step:
• Re-seat and inspect the upper rack rollers and rail track:

Fully extend the upper rack and locate the two roller assemblies on each side.

Pop each roller off its track wheel and visually inspect for any plastic debris or misalignment.

Clean the track grooves with a soft cloth to remove buildup, then snap each roller back onto the rail—listen for an audible click to confirm it’s fully engaged.

Gently slide the rack in and out a few times to verify smooth, secure movement without lifting off the rails.

Hi there. Thank you for sharing your experience with the LG LDTH7972S Dishwasher. We understand your inquiry, and we’re here to support you. The middle rack is designed with ball-bearing glides for smooth operation, and if these components become misaligned or dislodged during use or installation, it can affect movement. We recommend checking that the rack is seated evenly on both tracks and that the stoppers are securely in place.

Hello there, Stella. Thank you for sharing your experience with the LDTH7972S dishwasher. We understand the drying performance hasn’t met your expectations. While this model includes Dynamic Heat Dry™ for enhanced drying, performance can vary depending on the rinse aid usage, water temperature, and dish placement. We recommend making sure that rinse aid is always filled, as it plays a crucial role in drying, and selecting the Extra Dry or Night Dry option for improved results.

Regarding the noise, we appreciate your effort in adding insulation. The unit is designed for quiet operation, so if the sound seems unusually loud, it may be worth checking that the dishwasher is level and not in contact with surrounding cabinetry.

Please send us a private message on social media @LGUSSupport so we can provide more tailored support and ensure your dishwasher is performing at its best. We’d love the opportunity to help further.
