Introduction

The first thing you might notice about the GE GDT550HSDSS dishwasher is the number of buttons on its control panel. This intimidating machine, with an MSRP of $699, is all about giving you choices. It’s like the car with power everything, Bluetooth, GPS, and a Bose sound system.

The second thing you'll notice is the Energy Smart button. If you live in one of the few places in the US where smart electric meters have been deployed, this GE can look at your electric rates and decide when it's cheapest to run a wash. That makes it one of the first smart grid capable appliances on the market. Although the GDT550HSDSS overflows with extra options, its performance is middling.

Design & Usability

If looks could kill...

The GDT550HSDSS looks super serious. The stainless steel door gives it the impression of a heavy-hitter, especially when there’s steam coming out of its air vent in the corner. The top-mounted control panel has a total of seven buttons and 14 indicator lights. Simplicity and modesty have clearly been forsaken here: this machine’s design is all about intimidation.

They look like the grille of an 18-wheeler, barreling down the interstate with a rush delivery of cold, watery justice. Tweet It

When you open that door, you’re going to be greeted by a pair of full-size cutlery baskets staring you in the face. Hanging off the front of both racks, they look like the grille of an 18-wheeler, barreling down the interstate with a rush delivery of cold, watery justice. Those baskets make the racks feel cramped, but we still found that the GDT550HSDSS can fit ten place settings and a serving setting just fine.

Jumping back outside again, the intimidating control panel is actually very simple to use. Intuitively designed, you basically start from the left, first by choosing your wash cycle, then moving along to the right while picking the additional wash options, such as the steam pre-wash and wash temperature boost. Audible beeps and indicator lights confirm your choices while guiding you along. The very last button you reach on the right side is the Start button. After that, you just shut the door, and the bruising commences. Sitting dead center at the top of the door is an LED. When that light turns orange, you know that IT. IS. ON. When the GDT550HSDSS is done taking names, that light turns green and a short, pleasant jingle plays.

Features

Choices, choices...

The GDT550HSDSS is one of the few appliances already on the market that's compatible with smart grid technology, which can charge different rates depending on time of day. "Smart" electric meters can also communicate with appliances to let the user know how much it'll cost to run them.

The GE's Energy Smart cycle takes those varying rates (known as "dynamic pricing") into account. It will wait until energy costs are lowest to run a cycle, likely running in the middle of the night when energy demand—and the dynamic price of electricity—falls.

When it's not deciding when your dishes should be done, the GDT550HSDSS makes up for it by allowing you to micromanage your dishes. Want dry dishes when you’re done? Turn on the Heat Dry. Need to break out the big guns for tough, baked-on stains? Wash temperature boost and sanitize options will have you covered. Only have half a load? Change the Wash Zones to spray only the top or bottom rack to save water, time, and electricity. You can even put on your goggles and your most fancy hat and activate the Steam pre-wash option in lieu of soaking your dishes beforehand. Then call yourself a steampunk. You deserve it.

There are four cycle choices to choose from: Light, Normal, Heavy, and AutoSense. The first three are pretty self-explanatory, designed for varying levels of soil. If you're undecided, you can always leave it up to the AutoSense cycle, which uses the GDT550HSDSS’s soil sensors to determine how big a helping of vengeance needs to be served. There is no official “Quick Wash” cycle, but the Normal finishes in about 86 minutes, and is the GDT550HSDSS’s fastest cycle.

Performance

All bark, no bite.

So how did this brawny, versatile dispenser of soapy beatings do on our tests? Sadly, not that well. The GDT550HSDSS was run through our stain tests using its default settings. This allows us to make accurate scientific comparisons between machines. Stripped of its arsenal, the GDT550HSDSS proved to be mediocre in hand-to-hand brawls.

The Normal cycle, while able to remove most of the meat, egg, and milk stains, had a lot of trouble with baked-on spinach and oatmeal, which are the two toughest food stains at this level. On the bright side, there were only trace amounts of redeposit, indicating at least that particles that have been washed off were being properly drained away. The Normal cycle clocked in at a brisk 86 minutes.

The Heavy cycle performed a bit better with the spinach and oatmeal, but had problems with the burnt cheese and burnt sugar. Once again, there were only trace amounts of redeposit, and the cycle finished in 144 minutes.

Our conclusion is that the GDT550HSDSS on its default settings is less effective than some of its competitors. But it does give you fast cycle times, plus lower water and energy consumption, and an estimated annual running cost of just $27.42.

Conclusion

With great power comes... a user's manual.

In summary, the GDT550HSDSS does some things well, but dish cleaning isn't at the top of the list. We found that this machine had quick cycle times and is inexpensive to operate, but could only manage mediocre scores on our stain tests. But if you're looking for a machine that's smart grid compatible, this GE is one of your only choices.
