Four Reasons to Buy an LG Dishwasher

Four Reasons to Buy an LG Dishwasher

                                                                                                                               

Put Enhanced Cleaning in Motion

Achieve maximum cleaning throughout the entire cycle with LG QuadWash™. With four spray arms instead of two, QuadWash™ also includes Multi-Motion arms that rotate back and forth while spinning. The high pressure jets power-clean dishes from multiple angles.

Think you have to check on the dishes? Think

LG smart dishwashers come with SmartThinQ® technology built-in, so you can get smartphone notifications when a cycle is complete. That means less waiting and more time to yourself. You can even check on the cycle status with voice commands using the Google Assistant, so you don’t have to lift a finger.

Count On It

When you buy a dishwasher, you want something reliable that you can count on. Because the Direct Drive Motor uses fewer moving parts and operates more efficiently, LG confidently backs the motor with a 10-year warranty.

Easy Loading & Maximum Flexibility

The newly-enhanced EasyRack™ Plus system provides outstanding flexibility and convenience, adjusting to just about any load of dishes to help ensure optimal cleaning performance. Easy to adjust on-the-fly, this racking system can shift to handle any challenge your dishes can serve up.

  • Height Adjustable 3rd Rack

    The height adjustable 3rd rack gives you more space for hard-to-fit items.

  • Smooth Operator

    Even your hardest dish loads glide in and out smoothly with the help of LG’s Glide Rail.

Quiet Operation

LG's technological advances, like the Inverter DirectDrive motor and the advanced self-cleaning filtration system, were designed with quiet in mind. At 44dB, this dishwasher is among the quietest dishwashers in its class.

Rated 5 out of 5 by from Great Features I bought this dishwasher a little over a month ago and am impressed at how well it cleans. I also love that it has a light and a top drawer for items with long handles.

Rated 5 out of 5 by from Very quiet! We have had this three weeks and can’t be happier! Now conversations can be heard in kitchen and in living room! We really have to listen intently to hear it running. Great product from LG!

Rated 5 out of 5 by from So Far So Great!I looked for a dishwasher with fold down tines for larger items and a top rack for flat items and this one was the ticket. Cleans well and quietly.

Rated 5 out of 5 by from Quiet! Researched dishwashers and wanted one that was quiet--read reviews and LG was consistent with praising how quiet the unit was. Purchased my first LG appliance and I have to say that the dishwasher is extremely quiet, cleans dishes and has many features that my previous dishwashers lacked. The interior lighting is an additional bonus!

Rated 5 out of 5 by from Quiet and works great I love the machine! It looks and works great! If there is any one small knock is that the overnight dry still leaves a decent amount of condensation on your dishes if you leave them too long, but that is largely because we do not empty it quickly after the cycle is complete. Definitely recommend.

Does this dishwasher have a "sani-rinse" option?

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.

I am shopping for a new dishwasher. Is LG’s “Delicate” cycle safe for china and crystal or do I look for a specific model that says China/Crystal?

Asked by: EMH52
Hello, the delicate cycle in our unit should be used to clean delicate items such as fine china and stemware.

1)Does the stainless steel exterior hide finger prints? 2) what is the Electrical current

Asked by: Double TT
The Stainless Steel on this LG Top Control Dishwasher with QuadWash™ and EasyRack™ Plus, Model # LDT7797ST is not fingerprint or smudge resistant. Not sure if when asking about the "Electrical current" for this unit you are asking about its Electrical requirements or the current which is measured in amperes? The Electrical Requirements are 120 V, 60 Hz AC only and a minimum 15 Ampere circuit breaker...^IFV
