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.
