Temperamental and rusted rack

Katdmike 1/12/2025

Will stop working for 1-2 days and then magically start again. The racks rusted out by the second year. Trying to find replacement racks isnt easy and it is expensive.

Works well make sure its installed level.

iiambe 8/1/2024

We like the machine but weve had a few problems with it. I HIGHLY recommend getting the extended warranty. Several of the problems were because it wasnt installed level but I dont know if that was the cause of all of them.

Dishwasher

sueSueA 5/3/2024

The dishwasher has had major service twice since purchased. Getting thru to a rep and getting approval for repairs thru our purchased warranty agreement was a nightmare I have loved the dishwasher but cant believe the service wad so complicated to receive.

Great features

Elle 57 11/17/2023

I no get this in 2018 and it died already Love me the whole electric control panel is shot. Grant I did have a large family so it would get run every two days but still I think that is ridiculous to just die on me with no warning or anything. I did really like the 3rd rack and the adjustable second drawer very much allowing for taller things in the bottom or mid rack.

Very unhappy

TW47 9/6/2023

It is 3 years old and the soap dispenser broke. I used it probably 1 to 2 times a week. I dont use it at all now. The LG repairman saidjust throw the soap tablet in and that does not work. I am having to replace the dishwasher.

The last LG appliance I will ever buy

Greg96 9/2/2023

I bought this product approximately 5 years ago. I am replacing it this month. That will make this the shortest-lived dishwasher I have ever experienced. By the end of its life not only would the dishwasher not drain it wasnt clogged but it seems the control board was dying as well. To use the dishwasher usually meant flipping the breaker for the circuit on which it was attached to reset the electronics. Looking online it seems I am not the only person with the problem with the electronics. When the dishwasher worked it worked fine. It was silent and cleaned the dishes well and I liked the three trays and ability to move the glasses tray up and down to accommodate larger items in either the bottom or middle trays. But none of that matters if the dishwasher does not last. I would not buy another.

So Very Quiet

Marsha P 8/21/2023

The first time I ran this dishwasher I opened it up three times because I couldnt figure out why it hadnt started. It had started it was just that quiet. Its amazing to me that something like this can run and I can be standing right next to it and not even know it. But thats this dishwasher. I love the upper shelf I love the adjustable second shelf and it cleans like a dream. But back to being quiet. I was standing next to it talking to a friend in my kitchen and they asked if they should start the dishwasher. They couldnt believe it when I said it was already running I may have won a convert.

Cleans the dishes great when it works

Blankscan 5/17/2023

Sleek looking lots of features ample room for dishes but randomly decides when it wants to turn on and off. Sometimes it works fine other times it doesnt respond for weeks or months at a time.
