Bosch dishwashers are incredibly popular, but—like most home appliances—they have horrendously confusing names.
To the average customer, the 500 Series looks just like the 800 Series, and model numbers like SHXM63WS5N and SHPM65W55N all blend together. But, what do those series designations mean, and why do they matter?
That’s why the editors at Reviewed.com are here to help. After you’ve read our guide to Bosch dishwashers, you’ll be able to tell an Ascenta from a Benchmark, and a pocket handle from an external control.
Amazingly, the line used to be even more complicated, but Bosch simplified things a few years back, deleting the “Plus” designations. Now, there are five flavors of Bosch to choose from, each with its own colors, handles, and special features. Generally speaking, you get more features when you spend more money. Here are the differences, and how to tell them all apart.
What's The Same
All Bosch dishwashers have a few things in common: They can be mounted flush with cabinetry for a built-in look and they have a detergent dispenser designed for tablets. The 300, 500, 800, and Benchmark Series dishwashers all use the same wash system. The only differences are what options and features they add.

The detergent dispenser on all Bosch dishwashers is designed to work with tablets.
Every 300, 500, 800, and Benchmark dishwasher comes with with RackMatic, which allows users to more easily adjust the height of the upper rack among 3 height levels and 9 tilt positions to fit more items. (Some Ascenta models also offer RackMatic.) Models with hidden controls feature Bosch's InfoLight—a light that beams down on the floor to let you know when the dishwasher is operating. Some Benchmark Series dishwashers have TimeLight, which projects the actual time remaining on the floor beneath the dishwasher.

The Model Number Tells All
If you get confused, the best way to learn more about the dishwasher you’re buying is by taking a look at the model number.

500 and 300 Series dishwashers feature pushbutton controls, while the 800 Series has touch controls.
Though model numbers may look randomly generated, every SKU tells a story. For example, let’s examine the SHE33T55UC. Just from looking at this number, you can tell it’s a 24-inch model with external controls in the 300 Series, with a stainless finish. How?
- The initial S tells us that the product is a dishwasher. (A model number starting with a B is a fridge, and an H is a microwave.)
- If the second letter is an H, it’s a standard 24-inch model. If it’s a G, it’s a 24-inch ADA compliant model. If it’s a P, the dishwasher is a compact, ADA-compliant 18-inch model.
- The third letter tells us what the handle and display combination is. An E, for instance, means external controls. X means the dishwasher has a bar handle, while a P means the dishwasher has a pocket handle. A V means the dishwasher is panel ready.
- The fourth digit tells us what series the dishwasher is in. 3 = 300 Series. A = Ascenta, 5 = 500 Series, 8 = 800 Series, and P = Benchmark.
- The eighth digit tells what color the machine is. 5 = Stainless, 6 = Black, 2 = White, and 3 = Panel Ready.
Simple enough, right? Armed with this information, you can find the right dishwasher for your needs.
