LG - enjoying the new dishwasherLoving the 3rd rack for utensils and miscellaneous smaller items. It’s quiet and been performing as hoped. The controls are easy and intuitive.

Excellent FeaturesThis is the first dishwasher i have ever had that had multiple wash options. If they are relatively clean a fast hour wash, but if they are REAL dirty the mega 3 hour wash it is. I was a little worried when i saw it didn't have a heating element for drying but those concerns were quickly squashed after the first cycle. And the fact you can fold down supports on the rack comes in real handy for larger items. Now all my appliances are going to be LG.

The dishwasher is designed to fit into base standard kitchen cabinets that have a height of 34 1/2" (36" with the countertop).

Is there anyway this machine can run the complete cycle in less than 2 hours and 30 min. My old machine completed in 1 hour . This machine is suppose to be energy efficient but not at 2.5 hours
Asked by: Ivanaspenne
Even if it takes 2.5 hours, the ENERGY STAR® Qualified LG Front Control Dishwasher with QuadWash™, Model # LDFN4542S is still more energy efficient that your older dishwasher that completed wash cycles in an hour because the newer Energy Star standards are much more stringent than older standards. You can check the Energy Star Certification for this dishwasher in Canada for this unit if it is sold in Canada. Depending on the soil level of your dishes, the Turbo Cycle has a run time of 60 - 121 minutes, the Express Cycles has a run time of 34 - 104 minutes. The actual running time and cycle time displayed on the dishwasher's display may change depending on options chosen, soil level, water temperature, and hardness of water. Therefore, the display time and actual running time can be different....^Ivan

After installation, Is the dishwasher suppose to be proud of the kitchen cabinetry front face or countertop? Or, if installed correctly is the dishwasher FLUSH with the cabinets face?
Asked by: Hines
Like all other dishwashers, the LG Front Control Dishwasher with QuadWash™, Model # LDFN4542S is designed for installation in standard base kitchen cabinets. Standard base kitchen cabinets have a depth of 24" and if you look at the W x H x D dimensions for the LDFN4542S in its specifications on its product detail page on our site, its depth is listed as 24 5/8", so if installed correctly, it will be flush with your base kitchen cabinet. That 5/8" is barely noticeable...^Ivan

Does this dishwasher have a self cleaning filter?
Asked by: MRK6
The LG Front Control Dishwasher with QuadWash™, Model # LDFN4542S does not have a self-cleaning filter. The assembled filters have to be cleaned manually with a soft brush under running
water to remove food residue caught in filters to prevent the build-up of odor-causing bacteria and
possible drainage problems then reassembled before reinstalling them. It is recommended that you clean the filters after each load. If food debris remains in the filter, it may cause an odor. In areas with hard water, the filters should be cleaned at least once a month with a soft brush. There is a Recommended Filter Cleaning Schedule in the owner's manual that advises when to clean the filters depending on your number of loads per week...^Ivan
