Asked by Max.
This question was asked about the related product: LG - 24" Top Control Smart Built-In Stainless Steel Tub Dishwasher with 3rd Rack, QuadWash Pro and 42dba - Stainless Steel
- A:Answer There is no "average" - the cycles run for as long as they are programmed to run. For example, the one-hour cycle really runs for one hour, but it will be longer if you add extra drying time ("Dry Boost").

Q: QuestionCan the filter at the bottom be removed and washed? Also, is it fully functional without the app? (I don't need another "smart" anything.) Thanks!
Asked by MountainLady.
This question was asked about the related product: LG - 24" Top Control Smart Built-In Stainless Steel Tub Dishwasher with 3rd Rack, QuadWash Pro and 42dba - Stainless Steel
- A:Answer Hi there. Thank you for reaching out with your questions about the LG LDPH7972S Dishwasher. We understand the importance of keeping things simple and effective. Yes, the filter at the bottom of your dishwasher is removable and can be cleaned. Regular cleaning helps maintain peak performance and prevents odors or drainage issues. Here’s a quick guide: Remove the lower rack to access the filter. Turn the inner filter counter-clockwise to remove it along with the stainless steel mesh. Separate and clean the inner filter under running water using a soft brush or sponge. Reassemble and reinstall the filter, ensuring it’s properly secured. For detailed instructions, you can also check out LG Dishwashers – How to Clean Your Dishwasher Filter - https://www.lg.com/us/support/help-library/lg-dishwashers-how-to-clean-your-dishwasher-filter--20150210517756 Regarding app functionality, rest assured, the dishwasher is fully operational without the need for a "smart" connection. The app is an optional feature that provides additional convenience, but the core functions can be managed directly from the dishwasher. If you have further questions or need additional assistance, please send us a private message on Social Media @LGUSSupport. Our team will be happy to help! —Renzo

Q: QuestionWhat is the advantage of the Glide Rail feature on the 42 dba model LG ThinQ dishwasher?
Asked by TLC.
This question was asked about the related product: LG - 24" Top Control Smart Built-In Stainless Steel Tub Dishwasher with 3rd Rack, QuadWash Pro and 42dba - Stainless Steel
- A:Answer Zero - our top rack broke after two days of use. Bearings on the top shelf fell out and now the drawer is very difficult to slide back in. We have also had some cleaning issues with items on the top shelf. Buyer beware,

Q: QuestionIs there a secret to getting items in the middle rack clean? I’m never had a dishwasher that had so many issues on the middle rack. I’ve loaded differently, tried the heavy cycle, and went back to practically handwashing before putting in the unit.
Asked by TrishF.
- A:Answer Thanks for your post. I thought I had become a simpleton. I, too, rinse and often wash certain items b4 loading them. Consumed dairy products from glass mugs, glass bowls, spoons, forks and knives must be hand washed first, or they won't come clean. I actually dread loading the dishwasher now, a brand-new Quad Wash. The middle rack is particularly aggravating. I spend a lot of time tweaking that middle rack. The bottom part isn't much better, esp. when the silver wear basket is in use. Yes I know that it's removable, but the size of it prevents loading more than a couple of large items on the bottom *if* I chose not to hand wash a bunch of cutlery.

Q: QuestionCan you panel cover this machine? So it looks like part of the. Cabinetry? Thanks

- A:Answer Hey Andy! No, this dishwasher model (LDPH7972S) does not have an always on display feature. The hidden LED display counts down the remaining cycle time. When the dishwasher is not in use, the display disappears for a sleek look. ^Chris
