dish washer does not drain all the water do I need a repairmeb

Asked by amalie July 23, 2017

We regret the trouble you have experienced with this dishwasher. It is suggested to ensure the drain is unclogged, then it is recommended to try to clean out the filter screen. If this does not resolve the matter, then the unit may require service. To make service arrangements, you may either contact our Customer Interactive Center at 800-243-0000, or you can check our Repair Provider Lookup on our website, at

Asked by Allie December 4, 2019

What is the max height you can make this?

Asked by carbonsaab September 29, 2020

The LG SIGNATURE Top Control Smart wi-fi Enabled Dishwasher with QuadWash™, Model # LUDP8997SN is listed at 33 5/8" and standard kitchen cabinets have a height of 34 1/2" (without the countertop). Base cabinets can’t vary much in height. General design practices and building codes prevent variance in this. Base cabinets must be up to code and that means they must be “accessible.”, so the dishwasher can be raised to fit under the base cabinets, but also keep in mind that there is a dampening blanket wrapped around the top fo the unit that you will need to take into consideration when installing the dishwasher...^IFV

Do you want the best? Buy this!
Customer review from logo
[This review was collected as part of a promotion.] If you are looking for the best, money is not a matter. My friends and families don’t understand why I buy expensive appliances but I got LG Signature Refrigerator last year and fell in love. Even those families and friends love it. Had to buy a new dishwasher so I didn’t hesitate and purchased LG Signature Dishwasher. No question asked. It is genius, not a regular dishwasher. Top and middle loads are movable. It is good when only half top load needs dishwash. Really good feature for my house,half wash.We are only two people(me and my husband), when it was not enough to run then I rather do myself and used dishwasher(old) like drying rack. you can hook it with phone and start washer, Download cycle. I use auto and sometimes it is shorter I expect. Previous dishwasher was only set cycles so It took forever and felt like wasting electricity and water. You don’t even hear it is running. First couple times I had to put my ear on machine to see if it is started.

I would never buy an LG appliance again. I paid a lot of money for my LG dishwasher and within 3 months it broke down and it needed a repair. It was covered by warranty but still a pain as phone calls had to be made and even then, we had to pay out of our pocket. It has consistantly broken down 2 to 3 times a year in the last 4 years. Now it just never turns off. I have tried to call the company but for some reason, we just cannot touch base with someone now to get it fixed. I am sending it to the dump and buying a Kitchenaid.

Too many service calls!
Customer review from logo
Many issues within less than a year and more within 18 months. When it’s working it does a great job cleaning and I love the third rack. Needs to have a “rinse only” function. I will not be buying anymore LG appliances in the future.

Quiet, quick, dry, & convenient
Customer review from logo
We elected to go with LG signature refrigerator and range for our new home. The dishwasher was just an add-on that matched. However, we have been extremely pleased at all of its bells and whistles, on top of the standard features that are unbeatable. It is extremely roomy, quiet, and efficient. We love the third row for silverware & how the racks can move up or down.

Expensive, integration with Alexa laughable
Its a very expensive dishwasher. I could have bought a Miele or Bosch, and would next time, as they wash better and are more quiet. That’s not to say this machine doesn’t usually get things clean, it does, but not always. I have the mode that has a silver wear drawer at the top. That makes the room on the middle rack just a touch to low. And lowering the middle rack to fix that makes the lower rack just a touch to low. The controls are 1994 retro, minimal touch bottoms with double functions that require long presses to work, with indicator lights in illogica places and no good confirmation of a button press. Want s Turbo wash; find the small print under a touch button; press and hold for 3 seconds, and only when the number in the display changes do you know it’s on turbo. There is no dedicated Turbo light or button. Same for the Rinse cycle. There are times when the machine will not start, it simply flashes the run time, which is an indication of delay start, but no delay start is set. Takes picking another program; turning off and on, and then picking the program I went and running again This machine doesn’t dry too well. Upside down mugs in the middle rack have standing water after the extended end overnight drying cycle still. The integration to Alexa is laughable. “Alexa what’s the dishwasher status” is about the only useful command. If your rinse agent is low that’s the only status you will get trom Alexa. And the answer is always preceded with “LG Smat Think TV and Appliance”, doesn’t sound good. Also forget about starting your dishwasher from Alexa. Doesn’t work. Or stopping it. For the money I am not impressed.

Wouldn't recommend & wish I could retrun
I wish that I would have realized a few things about this dishwasher prior to purchase but being that this was my 1st dishwasher purchase I figured that a high-end price will get you a high-end dishwasher. The pros are this dishwasher is extremely quiet. Except for when it is draining, you cannot even tell it is running. The 'extra features' are pretty cool (adjustable rack height, lay-down tines, etc.) The filter is easy to remove & clean. The cons, however, make this machine a no go for me. The top rack doesn't clean very well. And I'm not talking baked on lasagna stains. I'm talking cups that had tea dry in the bottom. All of the the dishes must be almost completely 100% cleaned via a hand wash to come back out clean. In addition, the dishes NEVER EVER come out 100% dry. Even with rinse aid & the "Extra Dry" & the "Night Dry" features enabled, The reason is this dishwasher doesn't have a heating element to dry the dishes. It relies on the ambient heat of the dishes themselves to dry. Long story short, it's not enough to get it done. So, basically, you have to completely wash the dishes before putting them in, then you have to completely dry them after the 3 hour wash cycle, so what is even the point of having a dishwasher? It's a beautiful machine & it's roomy, it's just crappy at washing & drying & I feel like I tossed $1600.00 down the drain.

LG Signature Dishwasher
Customer review from logo
This dishwasher far outperforms our previous top-of-the-line dishwasher. Outstanding performance and lots of helpful features, and so quiet that the only time we hear that it's running is when it's pumping water out. We love the adjustable third rack and the flexibility (height, tines, etc.) of the other two racks, as well. Even the interior light is very helpful. Use a quality dishwasher detergent and rinse aid, and everything will come out sparkling clean. Best dishwasher we've ever had. Well worth the price.

Do not trust LG
I will never ever buy an LG product again. A few weeks after buying my dishwasher, I hit the child lock. Now it says IE and won't work. I called LG, and they booked an appointment 12 days later and when that repair person came, they said the problem was the house's water pressure, which must have just increased and needed to be fixed immediately, and the dish Asher should work as soon as the pressure issue is resolved. So I call my utility company, township and plumber and have a pressure regulator installed for $500, only to hear back that the pressure hasn't changed recently. Now LG said they can't come back for ten days past the last appointment (three weeks past the day it stopped working). At that time, they will assess the damage, then order whatever part is needed to fix it, and they have no idea how long that will take. Apparently, they have no timeline for the repair/replacement, it could take months. We spent so much money on this dishwasher, and at this point, and so far, have spent three days at home for appointments and I'm still washing dishes by hand. I'll never trust LG with my money again because they don't stand behind their products.

Don’t like this at all . Top rack doesn’t get clean and makes it impossible to put anything like glassware in the middle rack. It’s always wet inside after the cycle no matter what choice I make Really hate this. Wish I could return.
