The brand is proud to be ranked as the #1 and #2 dishwashers in a leading consumer magazine. 2002 - The on-going quality dedication and quest for innovation continue to make Bosch the leader in upscale appliances.

Ascenta Dishwasher Appearance
  • Stainless Steel Interior with Polypropylene Base
  • Each Ascenta dishwasher is built with a revolutionary new wash tub made from stainless steel with a reinforced polypropylene base - a first in the U.S.
  • Polypropylene is a high-quality, long-term tested material that makes the tub of their Ascenta dishwasher significantly more durable than conventional all-plastic tubs found in competing machines.
  • The patented tub is food proof and color fast.
  • Chrome Design Detail

Ascenta Dishwasher Convenience
  • Manually Adjustable Top Rack
  • EASYLOAD Standard Racks
  • Standard Silverware Basket
Ascenta Dishwasher Efficiency
  • 300 kWh/y Energy Usage - Most Energy Efficient in Class
  • Half Load Option
  • Use this option when washing small, lightly soiled loads that fill half or less of the dishwasher's capacity on both the top and bottom racks.
  • It dramatically reduces energy and water consumption.
  • An advanced sensor system determines the soil level in the wash water and automatically deletes fresh water fills if they're not needed.
  • Saves you time and money while cutting energy usage by 20%.
  • Flow Through Water Heater
  • In conventional dishwashers, water falls randomly onto an exposed heating element.
  • And since not all the water touches the heating element, this results in slower and less energy-efficient heating.
  • Bosch dishwashers, on the other hand, channel 100% of the water through tighter coils in a confined heating chamber.
  • Which heats the water quickly and efficiently up to 161 degrees Fahrenheit.
  • Condensation Drying
  • Built with a solid stainless steel tub, Bosch dishwashers utilize condensation drying to save you money on your energy bills.
  • Condensation drying works by heating the dishes with hot water from the final rinse.
  • Moisture condenses on the cool stainless steel tub and is drained, so your clean dishes dry without an energy-wasting active drying element.
  • ENERGY STAR Qualified
  • Proving once again that Bosch is committed to efficiency, all of their dishwashers are ENERGY STAR qualified.
  • NSF Certified
  • All their dishwashers boast certification from the National Sanitation Foundation.
  • Ensuring your dishes are 99.99% bacteria free at the end of each cycle.
  • This protocol establishes guidelines to determine sanitization and cleaning performance of residential spray-type dishwashers.
  • It includes minimum requirements to ensure that these machines will deliver wash water, detergent, and rinse water.
  • Which will render dishes, glasses, and utensils clean and sanitized.
  • The following Bosch wash cycles are NSF approved: Power Scrub Plus, Auto Super Wash, Auto Plus, AUTOWASH, Extreme Wash.
Ascenta Dishwasher Silence
  • 53 dBA Silence Rating - Quietest in Class
  • Two-Pump Motor System
  • By using two small pumps to individually wash and drain instead of a single large one, vibration and noise are dramatically reduced.
  • Smaller parts and a more contained motion contribute an important part to their sound-reduction system.
  • Leaving you amazed that the dishwasher is even on.
  • Suspension Motor
  • The more isolated a motor is, the less its vibrations can be transferred.
  • So they've suspended their two-pump motor to help absorb and minimize any vibration and noise to the housing.
  • As it is absorbed by rubber hammocks, letting you enjoy your time in the kitchen whether the dishwasher is running or not.
  • Insulation
  • Noise is also buried beneath the three layers of insulation inside their near-silent dishwashers.
  • Metal, cotton fiber and heavy-duty bitumen sheets capture and dampen sound to create a decibel level no louder than raindrops.
  • (Insulation package varies by model.)
Ascenta Dishwasher Automation
  • 4 Wash Cycles
  • Delay Start Option
  • With a nineteen or twenty four-hour timer, Bosch dishwashers work on your schedule.
  • Program them to start once guests leave or after you've drifted off to sleep.
  • Wait until you're out of the house, or run it in off-peak evening hours for even greater savings on your energy bill.
Ascenta Dishwasher Safety
  • Overflow Protection
  • Bosch offers a child lock for your children's safety and your peace of mind.
  • The control lock prevents changes to the wash program.
  • No Exposed Heating Element
  • Because their Flow Through Water Heater is not located in the tub and has no exposed heating element, it prevents plastic items on the bottom rack from melting.
  • It has the added benefit of protecting you from accidental burns during unloading.
