Rated 1 out of 5 by from (LDF 7551ST) Bottom dishes won't clean I've had this dishwasher (LDF 7551ST) since 9/2013. I should have returned it the first month it was installed, but I was foolishly optimist and thought I could work through the problems. I have to pre-wash everything that goes into the machine. Most of the time I just hand wash the dishes to avoid the bother. I have an error code that does not show up anywhere. It is two characters long and the first character looks like an unfinished character, almost as if part of the light display is burned out. The second character looks like a lower case letter h. At some point I'll see another dishwasher for sell and I'll buy it. One thing for sure, it will not be a LG brand. [This review was collected as part of a promotion.]

Rated 4 out of 5 by from excellent but hoses on the unit constantly leak love the unit but the hoses they use in the unit constantly thru time leak in between the ribs of the hose as shown in the photo the repair technician replaced one hose and told us that is the only warranty we get on the hoses so another different hose just started leaking in between the ribs totally different hose and we have to pay for it to get it fixed. I think they used a cheap hose to begin with we had the unit for less then 18 months and this is the second hose to spring a leak. I am now looking at the manuals to see the hose before I de-install it out of the kitchen counter to see if I could use a more superior type of hose and to see if it can be retrofit into the LG product. If they would have spent just a couple of bucks more on the quality of hose they could have avoided all these issues. I would have paid more just to not be inconvenienced [This review was collected as part of a promotion.]

Rated 1 out of 5 by from Very dissatisfied with this dishwasher. When I fill the lower rack and go to roll it back into the tub it falls off of the side tracks that are formed into the tub walls. The rack was replaced once which helped for a short amount of time and started doing it again. Very aggravating to get it loaded and then have it fall off of the track and have to reach in and lift the rack and try to get it back on the track. It also has not done a very good job of cleaning. The glasses always come out with out being clean and have to be hand washed! I have cleaned the filter and it did not make any difference. My old dishwasher did a much better job than this one. I will be replacing this one as soon as I can and it won't be this brand.

Rated 3 out of 5 by from SQUEALS VERY LOUD Our d/w is barely over a year old, and when filling squeals so loud it makes your teeth hurt. Have resorted to starting the washer and going out to dinner, because we dont want to be in the house. Even the dogs go outside. Hopefully LG will figure it out. Less than a month ago, it would not drain. Had to clean out the drain line, and found the tinyest little piece of a lemon peel stuck on a sensor. We are a family of two, and run less than 2 loads per week. Totally disappointed in this washer.

Rated 5 out of 5 by from This is a really quiet dishwasher! The dishwasher cleans the dishes very well and is unbelievably quiet. The only way that I know it is turned on and cleaning dishes is by checking to see the light blinking. I love the chimes at the end of the cycle that let me know my dishes are clean. It is also a very sleek and attractive appliance.

Rated 1 out of 5 by from love some features, really not happy with others I like how quiet it is when running , you can't hear it .I'm a rinser always (since I don't run it daily) and doing this the dishes will come out clean. However, if the kids put something in without rinsing it generally needs to be rewashed. The ability to lower the upper rack is great: I have found that leaving it lower works well for me most of the time. The feature that sold me was the adjustuble tines, but those tend to make more of mess because they don't hold where you move them. The racks bend in the middle when you put in glasses of different circumferences. Every time you pull out the upper rack the glasses are either laying on their side or completely upside down with the open ened facing up. Same problem with the bowls of different sizes on the bottom rack . I have already removed the covers for the silverware rack as they are way to much work to use. The three baskets offers the light conveinence of manueverbability, though are not fun to lift out when they separate and the silverware is all over the inside of the dishwasher. My experience with appliances has always been less features is better and wished I had kept to that when choosing a dishwasher this time. Also went against my better judgement and got the stainless, as it seems that is what everyone wants. Looks nice clean but there isn't a way to close the door easily with out touching the front and leaving fingerprints. The handle isn't each to reach with the door down, so it always looks messy. After having this product for a few months would I pick it again? NO!

Rated 1 out of 5 by from Broke a few months after getting it Looks like the main pump needs to be replaced after about 6 months. Do not recommend something that fails so quickly with a major problem!!

Rated 1 out of 5 by from Lemon I have only had this diswasher three months . The service guy came yesterday and basically told me my dishwasher is toast!. He has to order a new main board and drain pump. I bought this as LG was supposed to be highly rated. Now I have been without a dishwasher over a week and it will be another week before the parts are in. The service man said he has seen this problem before and most of the issues dont get resolved they have to replace the dishwasher.
