For me this is perfect.We purchased this dishwasher a month ago and I'm amazed who great this machine is. Super quiet and cleans and dries like no dishwasher we have ever owned. No spots and cleans everything. My wife loves the finger print free finish and the interior light. I really like the top silverware rack, it makes putting things away so easy. So happy we bought it.

Does a great job!We bought this dishwasher about a month and a half ago and we've been very happy with the performance. It has lots of features and we haven't used them all yet, but mostly because the few wash cycles we've used so far have worked so well we haven't need to try out the others. We use normal and turbo the most often, but sometimes use the auto option. The dishes have always come out clean even getting baked-on food. The 3rd rack is really nice for fitting extra smaller items in when they normally wouldn't fit and we've found that the dishwasher is very quiet. We've been very happy with the purchase.

Does the unit need a countertop air gap or can the connection be made under the sink?
Asked by: amenon
The LG Top Control Smart wi-fi Enabled Dishwasher with QuadWash™ and TrueSteam®, Model # LDT7808SS does not "need" and air gap. It can be connected to a Disposal without an Air Gap or connected to a Waster Tee without an Air Gap or to a Disposal or Waste with an Air Gap. The installation instructions in the owner's manual have instructions for any of those connections. Air gaps are the most effective means of preventing your drain from cross-contaminating your dishwasher with waste. If you want to protect your dishwasher from flooding with contaminated water, you need an air gap. Dishwasher air gaps are also required by plumbing codes in many locations so you may want to check your local building codes to see if it is required in your area. It's required by code in California but some people bypass this requirement and have something called a “High Loop” under their sink...^IFV

Does model # LG ( LDT7808SS) have a hard food disposal built in also does it have a removable filter you can take out and wash?
Asked by: Cwcc
The LG Top Control Smart wi-fi Enabled Dishwasher with QuadWash™ and TrueSteam®, Model # LDT7808SS does not have a built-in hard food disposal. It has an assembled inner filter and a stainless filter that can be removed so you can check the sump opening to see if any foreign materials need to be removed. The stainless steel filter has sharp edges so it should be handled with caution. The owner's manual has a chart for how often the filters should be cleaned according to the number of loads washed per week...^IFV

There was a previous question regarding NSF certification but the answer was not very clear. It appears no LG dishwasher has been certified by NSF for sanitation? Does the dishwasher not reach high enough temperatures?
Asked by: fluffydr
NSF certification (NSF/ANSI 184) requires that residential dishwashers achieve a minimum of 99.99 percent or 5-log reduction of bacteria and that they reach a final rinse temperature of 150º F. Sanitization performance is verified only when the dishwashers are operated on the sanitizing cycle. The Top Control Smart wi-fi Enabled Dishwasher with QuadWash™ and TrueSteam®, Model # LDT7808BD should be connected to a hot water supply with a temperature range between 120 °F (49 °C) and 149 °F (65 °C). This temperature range provides the best washing results and the shortest cycle time. To prevent damage to dishes, the temperature should not exceed 149 °F (65 °C). How hot the water is will depend on what temperature you set your hot water heater at. Although the dishwasher does not have a Sanitizing cycle, NSF Official Listings that are current as of Thursday, November 07, 2019 at 12:15 a.m. Eastern Time list this model as being NSF/ANSI 184 certified. You can contact NSF to confirm the status of the listing...^IFV

Does soap dispenser accommodate soap pods such as Cascade Platinum, and is there a dispenser for a rinse agent such as Jet Dry?
Asked by: Oregon Bunny
Typically, dishwasher pods are designed to dissolve upon contact with water so they can be placed in the Main Wash compartment for the LG Top Control Smart wi-fi Enabled Dishwasher with QuadWash™ and TrueSteam®, Model # LDT7808SS. We highly recommend that you follow the manufacturer's instructions on the package for the soap pods for their use in the dishwasher. The dishwasher has a separate compartment for rinse aid & rinse aid is strongly recommended to enhance the drying performance of the dishwasher. In order to be more energy-efficient, the hybrid drying system does not use a heating element to assist in drying, so a rinse aid plays an integral role in the drying process. If a rinse aid is not used, water may remain on the dishes and the tub. Rinse aid helps to ensure that the majority of the water has been sheeted off of the dishes at the end of the rinse and that the load is ready for the dry cycle...^IFV
