Bosch 800 Series SHX78CM5N Dishwasher vs Bosch Benchmark SHP9PCM5N Dishwasher

Both are 24-inch built-in Bosch dishwashers with CrystalDry and Home Connect, so the real split is quietness and cleaning hardware versus capacity. The Benchmark SHP9PCM5N is the quieter machine at 38 dB and adds PowerControl spray arms, AquaStop leak protection and TimeLight, and owners rate it slightly higher. The 800 Series SHX78CM5N holds 16 place settings against the Benchmark's smaller load and uses the Flex 3rd Rack for utensils. Buy the Benchmark for the quietest, best-protected clean; buy the 800 Series if fitting the most dishes per cycle matters more.

  • Choose the 800 Series SHX78CM5N if you routinely run full loads for a family and want the most place settings and a flexible third rack.
  • Choose the Benchmark SHP9PCM5N if you want the quietest operation, stronger lower-rack cleaning and built-in leak protection.

Questions and answers

Which is quieter, the 800 Series or the Benchmark?
The Benchmark is quieter at 38 dB against 42 dB on the 800 Series. Both are quiet enough for open-plan kitchens, but the Benchmark is the one to pick if the dishwasher runs during conversation or TV.
Does the Benchmark clean better than the 800 Series?
They share PrecisionWash and CrystalDry, but the Benchmark adds a PowerControl spray arm aimed at the dirtiest bottom-rack items. The 800 Series compensates with more room, so you load fewer, tighter cycles.
Which holds more dishes?
The 800 Series takes 16 place settings. The Benchmark's interior is smaller, so a large family will run it more often. For two or three people the difference rarely shows.
Is the Benchmark worth stepping up to?
Yes if quietness and leak protection matter to you. AquaStop and the 38 dB rating are real hardware differences, not app features. If you mostly care about fitting more dishes per load, the 800 Series is the better fit.
Do both work with Alexa and Google?
Yes. Both use Wi-Fi Home Connect with voice control through Amazon Alexa and Google Assistant, plus app cycles. The Benchmark also shows remaining time on the floor via TimeLight.
Which lasts longer?
Both are stainless-steel Bosch built-ins with similar construction and the same energy figure. The Benchmark's AquaStop adds protection against water damage, which is the failure that does the most harm. Neither listing states a written warranty, so confirm coverage with the seller.
