Bosch 800 Series SHX78CM5N Dishwasher vs Bosch 300 Series Dishwasher

The 800 Series SHX78CM5N is the better dishwasher of the two. It runs quieter at 42 dBA versus 46 dBA, adds CrystalDry zeolite drying that handles plastics, and has a top control panel that stays hidden. The 300 Series is a solid Bosch with AquaStop Plus and a third rack, but it sits a step below on sound and drying. Buy the 800 if quiet operation and dry plastics matter to you. Buy the 300 if you want Bosch build quality and leak protection and can accept more noise.

  • Choose the Bosch 800 Series if you want the quietest wash, top controls, and CrystalDry that dries plastic containers.
  • Choose the Bosch 300 Series if you want proven Bosch cleaning and AquaStop Plus leak protection and don't need the quietest model.

What reviewers say

Bosch 800 Series SHX78CM5N Dishwasher

Owners of the 800 Series consistently praise how quiet it is and how well CrystalDry dries plastics. Most criticism centers on long cycle times and the learning curve of loading the third rack.

What people mention
  • NoisePraisedOwners say it is quiet enough to run during dinner or while watching TV nearby.
  • DryingPraisedCrystalDry leaves plastic containers and lids dry, which reviewers single out as a real improvement.
  • Third rackMixedReviewers like the extra space but say the adjustable tines and shallow depth take practice to load.
  • Cycle timeCriticisedSeveral owners note that normal and eco cycles run long, especially with the extra-dry option.

Bosch 300 Series Dishwasher

Owners generally praise the Bosch 300 Series for its quiet operation and effective cleaning. Some mention that the third rack is less useful for larger utensils and that cycles take a long time. Overall, it is well-regarded for its reliability and performance.

What people mention
  • NoisePraisedOwners say it runs quietly, making it suitable for open living areas.
  • CleaningPraisedReviewers report dishes come out clean, even with tough messes.
  • Third rackMixedSome find the third rack handy for utensils, while others say it is too small for larger items.
  • Cycle timeCriticisedSeveral owners note that wash cycles take longer than expected.

Questions and answers

Which is quieter, the 800 Series or the 300 Series?
The 800 Series at 42 dBA is quieter than the 300 Series at 46 dBA. The gap is small on paper but noticeable in an open kitchen.
Does the 800 Series really dry plastics better?
Yes. CrystalDry uses zeolite to turn moisture into heat up to 176 F, so plastic containers come out drier than with the 300 Series' condensation drying.
Is the 800 Series worth stepping up to from the 300?
If quiet operation and dry plastics matter, yes. If you mainly wash glass and ceramic and close the kitchen door, the 300 covers the basics.
Do both have leak protection?
Yes. The 800 uses AquaStop 24/7 and the 300 uses AquaStop Plus. Both stop water intake if a leak is detected.
Which lasts longer?
Both use stainless steel tubs and share Bosch's core build. Longevity depends more on water hardness and loading habits than on the model tier.
Can I control either from my phone?
Both are Wi-Fi enabled with Home Connect. You can start cycles and monitor them remotely on either model.
