Bosch 300 Series Overview
The 300 Series marks Bosch’s entry into premium performance with a full stainless steel tub, RackMatic adjustable upper rack, and a standard third rack for utensils. Drying relies on condensation alone, so plastics often emerge slightly damp fine for plates and glass but less ideal for cabinets. At 46–48 dB, it’s quiet for most kitchens but audible in open layouts.
Best for budget buyers seeking Bosch reliability without extras.
Bosch 500 Series Overview
Stepping up, the 500 Series adds AutoAir drying, where the door automatically opens at cycle end to release steam and improve results on plastics over the 300. Noise drops to 44 dB for near-silent operation, and racks gain more flexibility with extra cycles like Half Load and Delicate for smaller or fragile loads.
This series hits the value sweet spot for everyday households.

Bosch 800 Series Overview
Top-tier, the 800 Series shines with CrystalDry technology, using zeolites to convert moisture into intense heat for bone-dry plastics and deep items 60% better than condensation. At 39–42 dB, it’s whisper-quiet, with a deeper MyWay third rack and PowerControl for targeted spraying on tough spots. Premium handles and panel-ready options add kitchen polish.
Bosch Dishwasher 300 vs 500 vs 800: Frequently Asked Questions
What are the main differences between the 300, 500, and 800 Series?
The 300 Series offers solid basics with condensation drying and 46–48 dB noise. The 500 upgrades to AutoAir drying (door pops open) and 44 dB quietness. The 800 tops out with CrystalDry for superior plastic drying, 39–42 dB operation, and advanced racks like MyWay.

Which series dries plastics the best?
The 800 Series excels here thanks to CrystalDry zeolite technology, which generates extra heat for bone-dry results even on hard-to-dry items. The 500 improves over the 300 with AutoAir venting, but plastics may still need a towel. The 300’s PureDry often leaves them damp.
How quiet are these dishwashers?
Expect 46–48 dB from the 300 (quiet but noticeable in open kitchens), 44 dB from the 500 (near-silent for most homes), and 39–42 dB from the 800 (whisper-quiet, ideal for open layouts).
Do all series have a third rack?
Yes, all include a third rack, but they vary: standard on the 300 for utensils, upgraded/flexible on the 500, and deeper MyWay on the 800 for bowls and mugs.
Which is the best value for most homes?
The 500 Series strikes the ideal balance better drying and quieter than the 300 without the 800’s premium price. Go 300 for budgets, 800 for top performance.
What cleaning features do they share?
All use PrecisionWash arms, stainless steel tubs, AquaStop leak protection, and RackMatic adjustable upper racks. Higher series add cycles like Half Load, Delicate, and PowerControl sprays.
Are they Wi-Fi enabled?
Select 300 models have Home Connect app control. It’s more common on 500s and standard on most 800s for remote monitoring and cycle customization.
How do I choose based on kitchen needs?
Budget or secondary kitchen: 300. Open-concept living: 500 or 800. Heavy plastic use or ultimate quiet: 800.
Can I load large pots in these?
Yes, all handle pots and pans with flexible lower racks. The 800’s deeper third rack frees up more lower space for bigger items.
What’s the warranty and reliability like?
Bosch offers a standard 1-year parts/labor warranty across series, with 5–10 years on racks/motor in many models. All series rank highly for longevity and low service rates.
