After years of hands-on testing, our appliance experts consistently recommend two standout brands — Miele and Bosch. Both are renowned German manufacturers celebrated for their innovation, reliability, and superior cleaning power, even in hard water areas.
But which one is truly the best fit for your home?
In this guide, we’ll compare Miele vs. Bosch dishwashers side by side, evaluating performance, water efficiency, noise levels, and smart features. Plus, we’ll highlight four top-rated models and share expert answers to common buyer questions, so you can choose with confidence and get sparkling-clean dishes every time.
Miele Dishwashers
For decades, high-end kitchens have turned to Miele dishwashers for premium dish care. The full catalog includes stainless-steel and panel-ready models, mainly with top-control models, plus a few front-control options.
Standout Miele dishwasher features include a QuickIntenseWash option that delivers a speedy wash in under an hour, along with Perfect GlassCare technology to delicately wash fragile dishware with pristine results.
If you’re eco-friendly (or just enjoy saving on operation costs), AutoOpen offers a final drying option that uses the air from your kitchen to finish drying dishes.
Select upgraded Miele dishwashers might include SensorDry with a system of sensors that monitor temperatures and adjust rinse and wash times accordingly.
Miele is also the first dishwasher brand to use an automatic dispenser. Together with their exclusive PowerDisk tabs, Miele AutoDos dishwashers release detergent quicker to break down food and debris from the start of the wash, resulting in superior cleaning.
Bosch Dishwashers
Compared to Miele, the Bosch dishwasher lineup is full of options that range from entry-level to affordable luxury. Bosch stands above the competition for two big reasons.
For one, Bosch includes 18 sound-reducing technologies on many of its dishwashers, making Bosch the quietest dishwasher brand in the U.S.A., with models as silent as 38 dBA.
Secondly, Bosch dishwashers come in three unique drying options. PureDry is the standard on all models, while CrystalDry uses state-of-the-art crystals to naturally heat moisture, turning it into hot air that dries dishes with superior results.
Together with PrecisionWash smart sensors and flexible rack designs, these dishwashers deliver high performance and convenience suited for any kind of kitchen.

What We’re Comparing
When it comes to comparing top appliance brands like Bosch and Miele, deciding which is better can be difficult. To make matters simpler, we’ve evaluated each brand according to these factors.
Performance
Bosch and Miele have an ongoing friendly feud over which brand is superior. As a consumer, you benefit from the race as each brand continues to push the envelope on what a dishwasher is capable of.
That means deciding on a dishwasher from the Bosch or Miele family will come down to your personal needs and preferences—both are top-performers that are sure to satisfy.
Between the two brands, accolades include:
- Winner of “Best of KBIS” Silver Kitchen Award: Miele G7000 dishwashers
- ENERGY STAR Most Efficient dishwasher: Miele G 7916 Sci
- Recognized ENERGY STAR Partner of the Year winner: Bosch, including its lineup of Energy Star dishwashers
On top of their winning performances, each brand offers exceptional durability. Bosch dishwashers are designed with a 10-year minimum lifespan, while Miele dishwashers are manufactured with the highest quality materials and craft made to last up to 20 years.
Drying Results
Bosch pioneered the inclusion of Zeolite crystals in dishwashers and continues to lead as one of the industry’s best-drying dishwashers with models that feature a CrystalDry option.
Using this feature, dishes can become up to 60% drier, and since a chemical response generates heat, the process is also energy efficient.
Miele offers similar results with condensation drying and AutoOpen drying that cuts down on energy consumption by evaporating moisture using fresh air, but in a head-to-head, Bosch consistently ranks better.
Efficiency
Bosch and Miele excel as eco-friendly dishwasher brands, offering innovative efficiency inspired by the conservative European lifestyle.

In short: choose Bosch for value and whisper-quiet performance, or Miele for unmatched durability and premium quality.
Bosch leads in drying performance thanks to its CrystalDry™ technology, which uses natural minerals (Zeolite) to transform moisture into heat — ideal for drying plastics and large loads.
Miele’s AutoOpen Drying is also highly effective and energy-efficient, especially for glassware and delicate items. However, for the fastest and most complete drying, Bosch’s CrystalDry takes the edge.
Yes, both Miele and Bosch dishwashers are well-suited for hard water conditions like those found in many desert regions.
Miele dishwashers come standard with a built-in water softener to prevent limescale and residue buildup.
Bosch dishwashers include similar softening technology on select high-end models, such as the 800 and Benchmark Series.
For homes in Arizona or other hard-water areas, Miele has the advantage thanks to its built-in system across all models.
When it comes to noise level, Bosch takes the lead as the quietest dishwasher brand in the U.S.
Bosch dishwashers operate as quietly as 38 dBA, ideal for open floor plans or late-night cycles.
Miele dishwashers start around 42 dBA, still extremely quiet by industry standards.
Both brands offer whisper-silent performance, but if noise is your top priority, Bosch is the quieter choice.

Bosch is still a strong contender with its high-end models featuring softening systems, but if hard water protection is a priority, Miele delivers the best results and lowest maintenance.
Keyword targets: “best dishwasher for hard water,” “hard water dishwasher Arizona,” “Miele vs Bosch for hard water.”
Bosch holds the title for the quietest dishwasher brand in America, with models as low as 38 dBA, nearly silent during operation.
Miele isn’t far behind, with its premium dishwashers averaging 42–44 dBA and superb insulation.
