A: I had the same problem too after a few weeks of install. I find that gently pulling out the middle rack all the way out helps to reset the drawers and allowing it to slide all the way back so that I can close the door.
Q: Is this unit supposed to ship with the sound insulation? They forgot it and it’s LOUD.
A: There should be a thick sound insulation blanket over the top and sides of the washer, our washer is unbelievably QUIET-much more quiet than dishwasher we’ve ever owned, including Bosch and Kitchen Aid.
Q: Can you place plastic items on the bottom rack, or will the dry boost melt plastic items?
A: I put plastic cover for covering food in the microwave on the bottom rack with no problem.
Q: Does this dishwasher use wifi?
A: The LG Smart Top Control Dishwasher with 1-Hour Wash & Dry, QuadWash® Pro, TrueSteam®, and Dynamic Heat Dry™, Model # LDTH7972S is a Wi-Fi-enabled dishwasher...^Ivan.

A: The green light will light after cycle is complete. The red light will light if there is some sort of error in addition to an error code being displayed where the cycle time would normally be displayed. As far as the other light I dont know since I have never seen that one.
Q: Does this model LDTH7972S have the auto open feature
A: No, but it does have a "night dry" function which circulates air if the dishwasher will remain closed for hours after cycle completion. Dishes and plastics come out dry and fresh.
A: The light times out and turns off. There is also a "night dry" function which circulates fresh air after cycle completion so you don’t have to open the door if you don’t want to. Dishes and even plastics come out dry and fresh.

This is the quietest dispatcher I've ever owned and the dishes come out very clean. The only questionable performance area is the third tray at the very top. I love that there is a light that turns on when you open the door like a refrigerator.

I had a lot of trepidation about a dishwasher purchase after reading the reviews of various across multiple retailer websites, including this very model. I read a lot of complaints about this dishwasher’s ability to thoroughly dry the dishes, the noise level, unclean dishes and error messages. I am happy to report that this far, I thoroughly disagree with the negative reviews. Noise Level: Our previous Kitchen Aid dishwasher was 14 years old, and our new LG is significantly quieter. We installed the sound buffer under the stainless toe kick, both packaged with the dishwasher. We did note that the noise level of the 1-hour wash and heavy wash cycles were slightly higher than a normal wash cycle. Drying Capability: Our old KitchenAid had incredible drying capability, and we feel the new LG is comparable; again, we’re puzzled by the negative reviews. We’re cautious to tilt dishes down to avoid water collection, and the few times a bowl or tray was left tilted up, naturally and understandably, there was water collection. We usually run the dishwasher when we head to bed, so we also don’t usually unload immediately, albeit, we have a few times and the drying capability met our expectations. Dish Cleanliness: We always rinse dishes before loading into the dishwasher and never load dishes with dried on food, and thus far, no issues with unclean dishes. We’ve even tested it with a very light rinse with some visible food residue, and still, the dishes were clean once the cycle was complete. Error Codes: We’re a little over 30-days in with no error codes to date. Other Features We Like: The dishwasher is connected to wifi, so we receive notifications on our phone when the cycle is complete, and to remind us to add JetDry if running low. In the app, we can even change the end cycle tune :) We also LOVE the top rack for low profile items like knives, utensils or container lids. Overall, we’re very pleased with our purchase. For reference, we’ve had our new LG for just over a month. We purchased the Geek Squad protection in the event that we needed it, which had better feedback than competitor appliance retailers’ customer service.
