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

Does this dishwasher have an option for no bar handle? If so, how can I make that happen? My entire kitchen is now matte black--it would be a terrible shame if I had to send everything back because I can't open my utensil drawer due to 0.5" overlap.

Asked by: Chris42
No, the dishwasher cannot be ordered without a handle. We apologize for the inconvenience.

Why is this not NSF certified for sanitation?

Asked by: NathanTex
Hello NathanTex. The National Sanitation Foundation has set a standard named NSF/ANSI Standard 184, which means that dishwashers bearing this certification kill 99.99 percent of bacteria when operated on the "sanitize" setting. In order to be certified, they also must reach 150 degrees Fahrenheit during final rinse. The ENERGY STAR® Qualified LG Top Control Smart wi-fi Enabled Dishwasher with QuadWash™ and TrueSteam®, Model # LDT7807ST does not have a "Sanitize" setting and it is recommended that you connect it to a hot water supply with a minimum temperature setting of 120 °F (49 °C), and 149 °F (65 °C) maximum...^IFV

How does the Matte Black finish compare to the "old" black finish on my other appliances? We tried the Black Stainless Steel and it wasn't a good look with the other appliances.

Asked by: Dicker
Hi Dicker. The Matte Black Stainless Steel finish on this LG Top Control Smart wi-fi Enabled Dishwasher with QuadWash™ and TrueSteam®, Model # LDT7808BM will be as different from the Black Stainless Steel finish as the Black Stainless Steel was different from the Smooth Black finish...^IFV
