What people are saying

Rated 5 out of 5 by from Dishwasher had a few issues but now GREAT! The dishwasher had a few issues, had LG service review and all issues were fixed promptly. We love the dishwasher and it is very quiet.

Rated 4 out of 5 by from good working dishwasher I bought this in 2014. I just had my first repair which turned out to be just a clogged drain line. I can't give 5 stars because the configuration of this dw leaves something to be desired. It took me a while to get the hang of it. Wine glasses don't fit except if over the divider. After 4 years 2 of the dividors rusted out. That said, I would buy another LG because mechanically it has been perfect.

Rated 2 out of 5 by from Had to repair 3 times. After one year, the dishwasher caused a flood in my house without it even running. Last year had to replace the pump as it wouldn’t drain. Most recently had to repair the door as the springs broke. I have other LG products which seem to be operating ok. I am very dissatisfied with the dishwasher and will not repair again. Most likely will not purchase another LG dishwasher when I have to replace this one.

Can this model be converted to panel ready ?

Asked by: sanjabodo
The LG Fully Integrated Dishwasher with Flexible EasyRack™ Plus System, Model # LDF7551ST, is not a panel-ready unit. LG does not manufacture any panel-ready appliances...^Ivan

Dishwasher doesn't dry. We have tried different cycles and the extra drying option and the dishes are still wet. How do we fix this issue?

Asked by: Sd13
We are having the exact same problem. We've been living with it and hand drying our dishes for over 6 months.... Very frustrating!!

THe noise level has become extremely loud. It sounds like an engine that is going to take off or a mower outside.

Did washer not heating the water? What can be done? 

Asked by: John JW
We regret the trouble you have experienced with this dishwasher. For proper operation, this machine should be connected to a Hot Water line, supplying a minimum of 120 degree water. The SANITARY cycle should raise the temperature higher than this. If it still 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 http://www.lg.com/us/support/repair/support-repair-provider-lookup.jsp.

My lg dishwasher is using way to much rinse aid. I fill up the resivoir, can do 2 loads and it's flashing to be filled. i have the dial at 1. Anyone else have this problem

Asked by: J Lynn
We regret the trouble you have experienced with this dishwasher. The lower setting for the rinse aid should restrict the use of the fluid. If the reservoir starts full, and is depleted in 2 cycles, 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 http://www.lg.com/us/support/repair/support-repair-provider-lookup.jsp.

Both of our side mounting brackets have broken off; what are the other mounting options or fix for this?  We have wood cabinets and granite counter top.  Would like to steady the machine for continued use.  

Asked by: Linda B
We regret the trouble you have experienced with this dishwasher. The rear feet of the dishwasher can be lowered in order to stabilize the machine. Beyond this, the only method of stabilizing the device is with the mounting brackets. Parts and accessories can be obtained through our parts distributor, MCM Electronics.
