Failed after 5 months

KennR 2/10/2024

The control panel failed after 5 months. The control panel is also not under warranty and the original part has been discontinued. LG does recommend a different replacement part at a cost of ~$266 about 1.4 the purchase price. Support is horrible never talked to a human the support email was so badly written I thought it was a scam and the support video was worse show images of car doors and other unrelated issues to troubleshooting a dishwasher.

Was great but is making bad noises after 6 months

BTJJ 2/4/2024

Love the design and features and it was whisper quiet as we had hoped. But over the first six months it has started getting more and more noisy. Based on internet searches apparently there is some sort of pump in the bottom that is prone to failure. Now we need to find time to start navigating the warranty process.

Nice upgraded dishwasher.

curbstone 12/11/2023

Wow what an upgrade from a 15yr old model. The drawers glide very smoothly there are many interior options for adjustments for various style pans and plates. This cleans very well. I think the dryer on my pervious model was a little better but this one is not bad. One of the coolest features is the interior light. This is also very quiet. Very happy.

Best Dishwasher Ever

Cori11 3/4/2023

This dishwasher is the best I have ever seen. The quality is super. It is quiet and washes the dishes the way they are suppose to be washed and they come out sparkling. I really like the lights inside and the organization of the trays. Ive had alot of different top of the line models from other manufacturers. They do not hold a candle to this one.
