The old Ascenta is now the 100 series, 100 Plus, and 100 Premium.
The difference between the series lies in their silence ratings.
They range from 46-50 decibels. The 100 Premium now features the nine-position RackMatic rack system, like the other Bosch dishwashers.
It is comparatively loud at 48 dB, has a lighter door, and offers basic cycles.
However, it does bear the Bosch label and is relatively inexpensive, usually priced at $599 after qualifying rebates.
You may not have all the features of a high-end Bosch dishwasher, but its reliability is unmatched. For builders, the Bosch brand holds significance, whereas homeowners might prefer more advanced models.
Pros: Price, reliability, main cycles, smart functionality.
Cons: Noticeable sound during a cycle, shallower racks, and lighter doors.

How to Buy a Bosch Dishwasher
Every Bosch dishwasher can heat the water to 161 degrees, and most use no-heat condensation drying.
Bosch Wi-Fi Connectivity
I hesitate to mention Wi-Fi so early, but all are Wi-Fi enabled, allowing you to turn the washer on or off remotely.
You can customize your cycles in the higher series as well.
Styles of Bosch Dishwashers
Many of the dishwashers are the same but with different-looking fronts. There are five styles of Bosch dishwashers.
Examine the series and features. Then, compromise on the style, like switching from a towel bar handle to a pocket handle or a regular front.
Regular: Essentially, it's a dishwasher with controls on the front.
Integrated: Controls on the front with a "scoop" handle under the control panel.
Pocket handle: Similar to an integrated handle, but with a spot in the door for your hand. The pocket handle has become popular because it matches every brand.
Towel Bar: Another integrated dishwasher with a towel bar handle. It's intended for towels and matches the handles of other Bosch appliances. However, it might not align exactly with different brands.
Panel-Ready: Some series are available with no front, allowing you to place your custom cabinet front on the dishwasher.
We recommend paneling only European-made dishwashers, like Bosch, Beko, and Miele, because they fit within a 24-inch space and won't protrude from your cabinets.
Bosch Dishwasher Wash Cycles
Dishwashers operate based on time and temperature.
A Bosch Heavy or Pots and Pans cycle will wash your dishes longer and at a higher temperature.
A China or Crystal cycle uses less time and a lower temperature, similar to most dishwashers.
The Water Softener Cycle removes hard water spots caused by lime deposits and softens water to appropriate levels.
Hard water can leave spots on your dishes and create other issues. Buying a dishwasher with a softener is an excellent choice, especially if you have well water.
The Eco Cycle is ideal for delicate dishes and glasses. This cycle reduces energy usage by lowering the temperature and cycle length. It's a shorter cycle, so don't use it for dishware with baked-on food.
The SpeedPerfect™ Cycle provides up to 25% faster cleaning on a normally soiled load of dishes.
The Favorites feature lets you program your customized cycle directly on the dishwasher.
Benchmark and 800 Series
These two series feature the "PowerControl" spray arm:
You can set the lower rack to wash in four different quadrants using Bosch's HomeConnect App.
This allows you to wash light, medium, and heavy loads and control the spray's intensity to clean china, baked-on lasagna dishes, or both in the same wash.
Bosch Dishwasher Drying Features
Bosch Dishwasher with AutoAir Drying
The ExtraShine option can be used with most wash cycles (except Rinse). It enhances the cleaning and shininess of dishes by raising the temperature and extending the drying time.
Essentially, it dries your dishes more efficiently by using additional time and temperature.
The Extra Dry option is ideal for use in tandem with any wash cycle. This option further enhances drying results by raising the temperature and prolonging the drying time.
Bosch consistently uses Condensation Drying, which combines residual steam with jet drying. This method provides average drying results and isn't as effective on plastics compared to brands like Miele or KitchenAid.
The next two cycles are newer and have enhanced Bosch's drying capabilities.They're featured in Bosch's superior dishwasher models.
Bosch's AutoAir drying system automatically opens the door to expedite the drying process at a cycle's end by releasing steam and heat.
If you prefer washing and drying dishes at night, AutoAir is an especially useful feature. The residual steam doesn't condense back into water, leaving a thin coat on your dishes.
AutoAir is exclusive to Bosch's 500 series models. Brands like Miele, some Samsung models, and Beko also offer similar features.
Bosch dishwasher models equipped with CrystalDry contain Zeolite. This volcanic element is versatile, used in everything from supplements to industrial cleanups.
In dishwashers, Zeolite generates heat and absorbs moisture – exactly what a drying cycle should accomplish.
We tested Zeolite in Thermador dishwashers (manufactured by the same company as Bosch) in their 20-minute wash and dry cycle and found it effective, even on plastics.
The CrystalDry feature is available in all Bosch 800 and Benchmark series models.
What Are the Best Bosch Dishwasher Features?
1. Bosch Dishwasher Racks
Every dishwasher, except the 100 series, has a third rack. The higher-end Bosch dishwashers feature a more flexible rack.
Adjustable RackMatic: The top rack can be adjusted both vertically and horizontally. It offers nine positions to accommodate a variety of plates and trays.
3rd Rack Configuration: Ranges from the 100 Premium to the Benchmark series, providing storage for silverware and more.
In our tests, we found that 44 decibels is quiet enough that you won't hear your dishwasher running.
However, it's unnecessary to upgrade from a 44 dB model to a pricier one solely for reduced noise. The upgrade is only justified if you appreciate other features.
Bosch's 500, 800, and Benchmark series either meet or surpass this standard. Here's a sound comparison between 44 and 55-decibel dishwashers in a kitchen setting:
3. Leak Protection
All Bosch dishwashers come with leak protection. The AquaStop feature employs sensors to halt water intake in their advanced models, spanning the 300 to Benchmark series.
4. Bosch Dishwasher Reliability
Dishwasher Reliability for 2023
The following service rates are based on a minimum of 100 products sold and a total sample size of over 8000 units over a 12-month period.
Signature Kitchen Suite
Fisher & Paykel
Bosch ranks as one of the most dependable dishwasher brands, with only 5.1% requiring repairs in the first year. This is in contrast to 6.2% and 6.7% for their main competitors, KitchenAid and Miele, respectively.
The drying capability of the 500 series is commendable, but the 800 and Benchmark series particularly stand out in this regard for their price point. Only Miele's G7000 series performed better.
Why You May Not Want a Bosch Dishwasher:
Cost: Bosch's superior dishwashers are priced between $1149-1349. Many other brands have reduced their prices, so it might be worth considering other options.
Quietness: The story has two sides. The 100 and 300 series don't achieve the 44-decibel quietness benchmark, operating at 46 to 50 decibels.
No Hard Food Disposer: If you dislike scraping your dishes clean before loading, prepare to clean the filter located at the dishwasher's base. That said, several other brands, including Miele and KitchenAid, also use filters.
No Designated Bottle or Silverware Sprays: Brands like Profile and Beko offer specialized sprays to cleanse residue from the bases of sports and baby bottles.
