GE GDT580SMFES Review
Some fancier options are present, but you probably won't even need them
It sure is nice to get an unexpected bonus. That's exactly how it feels to use the GE GDT580SMFES (MSRP $849), a dishwasher that has options for adjusting the wash temperature, choosing whether to wash just the upper or lower rack, or using steam to loosen up heavy stains before the wash. You probably won't need to get that fancy, though: the Normal wash on the GDT580SMFES does plenty of work on its own.
Design & Usability
Scaled down, but not lacking
As far as design goes, the GDT580SMFES features GE's Slate finish. The unique color is not reflective and, as its name suggests, gives the appliance a stone-like, earthy tone. If you don't like to stray too far from tradition, the GDT580SMFES also comes in stainless steel, black, and white.
The GDT580SMFES takes a few design cues from its more impressive cousin, the GE Profile PDT750SSFSS. In fact, it feels like a scaled-down version of the Profile: the control panel is hidden on the top of the door, and the buttons are similar as well—the only difference is the lack of a fancy LCD screen.
Looking inside, you'll find that the GDT580SMFES shares the same stainless steel interior, cutlery basket that splits in three, and numerous collapsible tines as the PDT750SSFSS. However, as this model is only about half the cost, it's obviously missing a few perks: Namely, there are no reversing quad-blade wash arms or dedicated bottle wash jets to be found here. Like its pricier counterpart, the GDT580SMFES holds ten standard place settings and a serving setting.
No Express service
The GDT580SMFES's selection of cycles and options are nearly identical to another GE dishwasher: the GDF570SGFBB. For cycles, you can choose between Light, Normal, or Heavy depending on how soiled your load is, or choose AutoSense to have the machine sort that out. Like the GDF570SGFBB, this dishwasher doesn't have a quick wash option: The Light cycle is the closest equivalent, and it takes about 53 minutes to complete.
When it comes to customizing a wash, the GDT580SMFES offers two options for increasing the wash temperature— Boost and Sanitize, a steam prewash option, Heated Dry, and the familiar 1 to 12-hour delay and control lock. You can also set the wash to cover only the upper or lower rack, which will save you water and time if you're only doing half a load.
The Normal wash cycle is all you need.
We were generally impressed by the GDT580SMFES's washing performance, but it was its Normal cycle that really amazed us. A vast majority of the stains we used, which included meat, milk, and oatmeal, were washed away. More importantly, none of the stains were redeposited—a problem some dishwashers have when soils from one dish gets sprayed to another during the wash. The whole process only took 90 minutes, but did not include a drying cycle.
The Heavy cycle scored about the same as the Normal on similar stains, but mostly because the Normal cycle left very little room for improvement. However, while this cycle was able to handle baked-on lasagna and burnt sugar well enough, it struggled with the burnt cheese stains. This cycle also took nearly two and a half hours, and engaging the Heated Dry option would add at least another hour: Save this one for just before bedtime.
On both of these cycles, we noticed that there were some coverage problems on the top rack. Items placed at the corners were consistently not as clean as the ones closer to the center. Sadly, this problem is not uncommon in dishwashers, and Samsung's WaterWall technology aims to fix this very problem. Until then, the best solution is to simply place the heavier stains closer to the middle of the top rack.
This estimate that for an average family in America, this dishwasher will only cost around $28.04 a year in utility costs, which is below average. However, if you engage Heated Dry regularly, you can expect that number to be a bit higher.

Why We Like It
The extras feel like value added.
The Normal cycle is the bread and butter of a dishwasher, and it's rare that we find a machine that nails it as well as the GDT580SMFES. As the most common cycle used for everyday loads, we like to see Normal cycles that are fast, thorough, and efficient—the GDT580SMFES accomplishes exactly that.
The extra wash options are just icing on the cake. The majority of your loads can be handled by just a Normal wash on default settings, but it's also nice to be able to use Steam prewash on some of the tougher stuff instead of scraping the plates yourself.
