What People Are Saying

Rated 1 out of 5 by from ldf7551st will not power on less than 5 years old I would not recommend buying product its a piece of junk.

Rated 2 out of 5 by from Poor quality of racks When we built our house 18 months ago, I wanted all new, nicer appliances. So we went to Best Buy and bought all LG Stainless Steel Appliances, including this dishwasher. This is perhaps the worst dishwasher I have ever owned. The tines fall over anytime you place anything heavier than plastic in the bottom rack. My dishes are Longaberger Pottery, therefore are heavier, and they make the tines fall over. If you load it too much to keep the dishes and the tines up, then the dishes don't get as clean. There should be some kind of locking mechanism on the tines to keep them in the position you want them to be depending on the load you are washing. This would have been a simple engineering fix, that I am surprised your engineering department didn't think about. This dishwasher also does not clean the dishes as well as I would have liked on the regular setting. You have to really rinse the dishes well prior to placing in the dishwasher, and then I always put it on dual wash, which is a longer cycle, hence using more water and electric. So not really a cost savings. It is however, a quiet dishwasher. I love my other other LG products, but I will not be buying a dishwasher like this again.

Rated 4 out of 5 by from So so quiet This dishwasher looks great. So quiet compared to my old unit. Cleans thoroughly. I just don't like cleaning filter/screen (it will smell if you don't). Best Buy installed and did a great job.

Rated 3 out of 5 by from issues with draining The dishwasher is nice and quiet. However, there are two major issues with this dishwasher: 1. the dishwasher does not always drain properly. There is a filter but objects do get past the filter somehow. This causes something as small as a poppy seed or smaller to prevent the dishwasher from draining properly. I am now having to remove the drain tube from the disposal and using a wine vacuum to suction the water from the drain hose. I need to do this daily. I also have to completely rinse the dishes before putting them in the dishwasher. To me, this defeats the purpose of the "energy saver" label. You should not need to completely rinse dishes before putting them in the dishwasher. The dishwasher is 'supposed' to wash the dishes. Getting large food deposits off seems normal. However, I am finding that need to have the dishes washed prior to putting them in the dishwasher. The 3 different techs that have come to my house have all said that you really do need to rinse thoroughly before putting dishes in the dishwasher. 2. The other issue that I have with the is the rack. The rack does not fit normal dishes well. The rack adjustments to address different size dishes do not stay in place when stacking the dishes. From my point of view, the rack works but it is not the most efficient system. I gave this dishwasher a 3 star rating. I will add that I tend to have an incredibly high level of tolerance for disruption and malfunction. Other folks who experienced similar problems may have scored the overall ratings much lower. I am a huge LG fan. I purchased a refrigerator, washer and dryer, television and other products. When the stove goes - I will probably go LG as well. I was betting on the LG name when I got this dishwasher. They haven't been in the dishwasher market for long and it shows.

Rated 5 out of 5 by from Love my dishwasher! We have had this dishwasher for a year now, and I absolutely love it! It's incredibly quiet, that I have to go back in the kitchen and make sure I did turn it on. My husband and kids were a little leary to use it at first, scared they would set something wrong, but they found out quickly that it's as easy as 1,2,3. I'm also impressed with the sleek look and design. It compliments our kitchen really well and the black finish is easy to keep clean!

Rated 1 out of 5 by from Doesn't clean and racks are a pain We purchased a new home and wanted to install all top of the line appliances. I wish I would've read the reviews and did add'l research. I always rinse dishes so I do not put them in covered in food. Dishes do not come out clean and they come out dripping wet. I've tried different detergents, pods, liquids, rinse agents, etc and they are not clean Racks are a pain to deal with. They constantly collapse and the glass rack does not fit glasses in more than half of the rows because of their angle. I'd return it if I could. My basic model was much more efficient than this. Definitely not worth the money

Rated 4 out of 5 by from Great Dishwasher I use my dishwasher about once every two weeks The dishes are always clean and ready to use. I have not had any problems with this dishwasher. I enjoy the options, especially the quick wash (if few dishes). The washer is not loud, barely notice that it's on when in the kitchen. I enjoy using this product.

Rated 5 out of 5 by from Silence is Golden I love this dishwasher! You can stand next to it and not hear it run. It cleans the dishes spotless and so easy to use. I did have a problem with the lower rack and the prongs falling over when loading the dishes. Contacting LG, customer service said that there had been a design change and they sent me a new lower rack. Loading the dishes now is a dream! Thank you LG!!!!!

How do I get the blue light to turn off and not blink?

Asked by: Derosama
We regret the inconvenience you have experienced with this dishwasher. The model design with one indicator light is designed to blink during operations. There is no setting to deactivate this indicator light.

What size and type of screws are used to side mount LDF7551st?

I understand mounting screws came with the dishwasher, but we are now replacing counter tops and can no longer mount on the top and the original screws are gone.
Asked by: Verl
We appreciate your interest in this dishwasher and its proper installation. There are no specific recommendations for the screws involved with this installation. They need simply to be wood screws sufficient to anchor the unit and the mounting brackets to the cabinet as needed.

Drain water temperature when SANITARY is ON

When the SANITARY is ON the manual says it heats the water up to 160F at the final rinse. Does that mean when the rinse cycle ends it directly drain the 160F water to drain pipe? My drain pipe could not handle that.
Asked by: LGuserabc
We appreciate your interest in this dishwasher. Yes, the water that drains will be the same temperature as that which runs during the rinse cycle. As such, the 160+ degree water will be running through the drain pipes.

Whistling Noise Occurs During Wash Cycle

Hello, Has anyone experienced a whistling noise during the normal and quick and dry cycles for LG model dishwasher LDF7551ST? THis has just recently started... began with the quick and dry cycle but is now occurring during the normal cycle... Thanks
Asked by: indianafarmgirl1
We regret the trouble you have experienced with this dishwasher. There are different possibilities as to the cause of this sound. A whistling could be related to the water lines being restricted, or it could be from the chopper blade in the on-board soft-food grinder. If these do not appear to be case, then the dishwasher 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

The dispenser cover on my LG dishwasher gets stuck sometimes and won't open to release detergent, even the release button will not open it.

I have the model LDF7551ST dishwasher. The upper rack is not in the lower position and nothing is blocking the cover from opening. Pushing the release button does not open the cover. I have to manually push the cover open and the detergent is sitting there unused. Do I need to replace the dispenser?
Asked by: sawickc
We regret the trouble you have experienced with this dishwasher and its components. It is recommended, first, to attempt to clean the dispenser cup, door, and hinge areas. If the door does not open properly after that time, then the unit will likely 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

The dishwasher won't power on; is there anything to try before scheduling a service appointment?

It looks like the dishwasher didn't finish the last wash cycle. There is still water in the bottom, but the dishes appear to be clean. Now the dishwasher will not turn on. I made sure the circuit breaker hadn't tripped. Still can't get it to do anything, just wondering if there was anything I could try before scheduling a service appointment.

On the icon panel, I can't turn on my dishwasher it has a symbol with a star flashing above it. Why won't it turn on?

It is by the 3 lights that come on when I turn on the dishwasher, that is as far as I can go. My dishwasher won't turn on. I don't have any info on it as I bought this one as a returned item.
Asked by: Fordgirl
On mine, when the star flashes, it means that the jet dry is low or empty. I would not think that would stop it from starting though.

What is the part # for the drain hose assembly?

My dishwasher model # is LDF7551ST. AEM69493803 does not fit. The drain hose that extends from the white plastic loop to the sump under the dishwasher is too short.
