What people are saying

Rated 3 out of 5 by from Takes forever to run and can not get wi-fi Bought this and liked that i had wi-fi in case I forgot to start it. Cons Cannot get it to pair with my phone (Lights Thermostat fridge and all do so I know some of how to get it done. It takes forever to wash, It doesn't clean well without hand washing prior. The pro is it is quiet and that is about all.

Rated 5 out of 5 by from Lots of options! I am very pleased with my first ever dishwasher. It is amazingly QUIET! I was a little surprised at how long it takes for a load on AUTO setting to run, but I did have it on extra dry setting. There are many different wash and dry settings. I still have not used them all. My brother who used to sell appliances was also impressed!

Rated 5 out of 5 by from I love my Dishwasher! They delivered my new L G Dishwasher right before Thanksgiving. Just in time for many loads to be washed! .I love the light and the top rack is wonderful also.I will get many years of use I am sure. You can't beat an LG appliance. LG offers a longer warranty but I am sure I won't even need to use the warranty because it was built by LG. I recommend if you are in the market for an appliance "Buy an LG" you will not regret it!

Can I use soap tablets?

Asked by: Ltdedt
The LG Black Stainless Steel Series Top Control Dishwasher with QuadWash™ and EasyRack™ Plus, Model # LDT7797BD is designed with a main wash compartment that ypu need to add liquid dishwasher detergent to so it can be dispensed at the correct time during a wash cycle. Incorrect detergent may cause the dishwasher to fill with suds during operation. Excess suds may reduce wash performance and may cause the dishwasher to leak. If using detergent tablets, do not use liquid rinse aid since they already include rinse aid. For further instructions on their use with the dishwasher, please refer to the instructions on the packaging or contact the manufacturer...^IFV

Does this model have the ability heat the water beyond the temperature that the main house water heater is set at? My dishes are never very hot or clean at the end of a cycle even when using high temp. I'm wondering if I just have a defective unit.
