Bosch dishwashers are known for incredible cleaning power, good looks, and a wide variety of additional features. Though you can't go wrong with any Bosch dishwasher, it is important to know what you can expect from a unit in their 300 series or a unit in their 500 series. Let's explore the differences between these models and the kinds of features you can expect to see on each dishwasher.

What is a Bosch 300 Series Dishwasher?

Bosch 300 Series dishwashers come with tons of features that make them very helpful in the kitchen at a comfortable price. These are considered some of the quietest dishwashers available, and they come with powerful cleaning and drying capabilities. PrecisionWash technology, which you'll find on most units, makes use of sensors that will continually scan your dish load as it gets clean, and using these sensors the dishwasher will be able to send the PowerControl spray arm to target specific soiled areas to get them the extra attention they need. Many models in this series also come with RackMatic technology, which means you'll be able to adjust the height of the middle rack to better accommodate taller dishes. All of these features combine to give you a convenient dishwasher that can handle even the most intense load of dishes.

What is a Bosch 500 Series Dishwasher?

Bosch 500 Series dishwashers come with everything that the 300 series models come with and more. The main thing to note that you'll find in 500 series models is the AutoAir drying system. This convenient feature allows your Bosch 500 Series dishwasher to automatically open itself up after a cycle, saving you energy by allowing your dishes to air dry. Many models in this series also come with a flexible third rack. Though many 300 series models also double as third rack dishwashers, the flexible third rack on 500-series models and up not only provides you with a great space to load awkwardly-shaped utensils, but it also comes with fold-down sides to give you even more storage options.

As we said earlier, you can't go wrong with any Bosch dishwasher. Whether you decide to get a Bosch 300 Series dishwasher, a Bosch 500 Series dishwasher or any other model, you can be sure that you're getting a reliable dishwasher that can handle all of your dirty dishes. We hope this blog has helped you see the differences between these two great machines.
