  The LG LDF7551ST is a relatively quiet and large-capacity dishwasher with a lot of flexibility due to its adjustable upper rack and fold-down tines on both racks. Although it doesn't have the heated drying cycle found on many high-end models, it does have a stainless steel tub, an overflow detector and the ability to delay the start of the wash cycle for up to 19 hours. Other features include time remaining and rinse-aid indicators; a child lock; and variable spray settings (strong, medium, soft).

Models: LDF7551WW (White), LDF7551BB (Black), LDF7551ST (Stainless Steel)

What People Are Saying:

The LG LDF7551ST is on the 2012 Recommended list at Consumer Reports, which rated it very good in all categories tested -- washing, energy use, noise and ease of use. There are only a few online user reviews and those CostHelper found are primarily positive; about 75%-85% recommend this dishwasher, saying it's so quiet it can be hard to tell it's running, and praising its large capacity and easy adjustments for large or odd-shaped dishes. However, several mention the lack of a heated drying cycle or a hard food disposer/grinder. Only a few dislike this machine, reporting immediate and ongoing repair problems.
