  • Whisper quiet workhorse
    Reviewed by Rikk-n-Ang - December 18, 2020

    [This review was collected as part of a promotion.] This machine is silent. I have to actually focus with my ear right by the machine to hear it working. (Of course, the work light is on, but still) The 3rd rack is awesome. You can easily fit spatulas and even small prep bowls on the top thanks to the expandable sides. I love that the bottom rack has fold down racks, allowing for more room for larger bowls or pots. This machine is so flexible and versatile. We're very pleased with our purchase! Highly recommend!! My absolute favorite feature is the auto-open. Smart design and functionality.

  • Best dishwasher we have owned
    Reviewed by Brent - August 10, 2020

    (This review was collected as part of a promotion.) The Bosch dishwasher is the quietest dishwasher we have ever owned. It's also the first dishwasher with the third rack for utensils which has proven to be very very useful. Inclusion of the indicator light is very helpful because at times it's hard to know whether the dishwasher is running to the very quiet nature of its operation. Having the controls on the top of the door makes for a very clean appearance.

  • Great Dishwasher
    Reviewed by Jochew9 - May 13, 2020

    [This review was collected as part of a promotion.] For starters, my Bosch is the most quiet dishwasher I've ever owned. It cleans my dishes well. Enough different settings to do the task at hand. Not being the most savvy person. The only complaint I have is I sometimes can't figure out how to change a setting. So I just run it on the setting which is selected. I guess I'm saying it should be more user friendly. Especially for the senior population.
