Compiled from Twin Cities field data — 800-Series and Benchmark Bosch vs G 7000 Miele service tickets, 2022-2026.
Category-by-category comparison
Quietness (dBA)
Edge: TieBosch
Bosch 800-Series: 42 dBA, Benchmark: 38 dBA. Real-world third-rack rattle adds ~2 dBA.
Miele
Miele G 7000: 38–43 dBA depending on tier. AutoOpen drying door-pop adds noise at cycle-end.
Wash system
Edge: MieleBosch
PrecisionWash sensor + CrystalDry zeolite. Excellent on glass and plastic but the zeolite chamber is a $385 part if it fails (rare).
Miele
QuickPowerWash 58-minute cycle is the standout. Triple-spray-arm coverage rivals commercial machines.

Edge: BoschBosch
BSH parts network — 1–3 days for control boards, drain pumps, door latches. Most failure-pattern items truck-stocked.
Miele
Miele USA — 3–7 days for drain pumps and control boards. Specialty parts (AutoDos dispenser) 1–2 weeks.
Drain pump failure rate
Edge: MieleBosch
800-Series: ~7% by year 7. $245–$345 to replace.
Miele
G 7000: ~4% by year 7. $345–$485 due to access.
Service life
Edge: MieleBosch
10–15 years typical with annual filter cleaning. E15 fault is the #1 service call (drip-tray water).
Miele
15–20 years typical. F11 fault is the most common (drain restriction).

$1,800–$3,500 installed. AutoDos models reach $4K.
Repair cost over 10 years

~$285 average (less frequent failures but pricier per call).
Best fit
Edge: TieBosch
Daily-driver kitchens that want hospital-quiet performance at a 4-figure price.
Miele
Long-tenure homes where 18+ year lifespan justifies the premium upfront cost.
The verdict
Pick Bosch if you want the quietest dishwasher under $2,000 with same-week parts availability in the Twin Cities.
Pick Miele if you plan to keep the dishwasher 15+ years and value the 58-minute QuickPowerWash on heavy loads.
Avoid either if you can't commit to monthly filter cleaning — both brands punish neglect with E15/F11 faults.
Frequently asked questions
Which is more reliable?+
Miele. Miele G 7000 dishwashers typically last 15–20 years vs 10–15 for Bosch 800/Benchmark, and Miele's 10-year service-call rate is roughly half of Bosch (~4% drain-pump failures by year 7 vs Bosch's 7%). Bosch parts arrive faster in the Twin Cities and cost less per repair, so 10-year total cost of ownership is close — but on raw reliability, Miele wins.
Is Bosch or Miele more reliable long-term?+
Miele edges Bosch on raw lifespan (15–20 years vs 10–15) but Bosch's failure modes are cheaper to fix and parts arrive faster in the Twin Cities. Total 10-year cost of ownership is close — Miele wins by ~$200 if you keep the unit past year 12.
Which dishwasher is quieter?+
Tie at the top tier. Bosch Benchmark at 38 dBA and Miele G 7000 Diamond at 38 dBA are functionally identical to the human ear. Below the top tier, Bosch 800 (42 dBA) beats mid-Miele (43–46 dBA).
