Why the Bosch Benchmark SHP9PCM5N is Consumer Reports' #1 Dishwasher

If you are tired of pre-washing your plates and towel-drying your Tupperware, the market has an answer. Right now, the Bosch Benchmark SHP9PCM5N sits at the absolute top of Consumer Reports' dishwasher rankings. It earned a massive Overall Score of 85 out of 100, beating out over 120 other models.

But at a premium price point ranging from $1,766 to nearly $2,500, is it actually worth the investment? Here at CR Watchdog, we do not care about shiny showrooms—we care about the data. We cross-referenced independent lab testing with manufacturer specs to give you the bottom line.

Here is exactly why this machine dominates the competition.

The Most Reliable Brand on the Market

Before we talk about features, we have to talk about longevity. A fancy dishwasher means nothing if it floods your kitchen in a year.

According to survey data from over 66,000 Consumer Reports members, Bosch is the undisputed king of reliability. Out of 27 surveyed brands, Bosch ranks #1 for Predicted Reliability, earning a near-perfect 98/100. Furthermore, Bosch is one of only two brands to earn top-tier ratings for Owner Satisfaction (91/100), meaning buyers actually love living with these machines long after the purchase.

Lab-Tested Performance: Where the Benchmark Shines

In Consumer Reports' rigorous lab testing, the Bosch Benchmark SHP9PCM5N didn't just survive; it excelled.

• Exceptional Drying (5/5): The biggest complaint about modern, energy-efficient dishwashers is wet plasticware. This model earned a perfect 5/5 for drying. Bosch achieves this using their patented "CrystalDry" technology, which transforms moisture in the tub into heat up to 176°F, leaving even plastic storage containers perfectly dry.
• Whisper Quiet (5/5): This machine earned a top score for noise in the lab. With an operating sound level of just 38 dBA, it is astoundingly quiet. Because it runs so silently, Bosch includes a "TimeLight" feature that projects the remaining cycle time directly onto your floor so you know it is actually running.
• Energy Efficient (4/5): It boasts an Energy Star certification and carries an estimated annual usage cost of just $76.
• Ease of Use (5/5): Thanks to a highly flexible interior, CR awarded it a perfect 5/5 for usability.

Standout Features & Specs

Beyond the lab scores, this 24-inch stainless steel built-in model packs some serious engineering:

• PrecisionWash & PowerControl: A motorized spray arm targets the dirtiest dishes on the bottom rack for a deeper clean without the need to scrub or pre-rinse.
• RackMatic System: The adjustable upper rack easily shifts into 9 different positions to fit tall stemware up top or massive stock pots down below.
• Flexible 3rd Rack: A top rack with fold-down wings to accommodate bulky utensils and ramekins.
• 24/7 AquaStop: A highly engineered leak containment system featuring sensors that can automatically close the water inlet and pump out water if a leak is detected, even when you aren't home.
• Home Connect: It is Wi-Fi enabled, allowing you to access smart cycles, monitor progress, and control the unit via your smartphone or voice assistants.

The Watchdog Verdict

The only real "con" noted in the CR testing is that the filter requires manual cleaning, meaning you will occasionally need to rinse it out in your sink to keep the machine smelling fresh. Its cycle time for a heavy load is also on the longer side at 150 minutes.

However, those are minor trade-offs for a machine that cleans beautifully, dries plastics flawlessly, operates in near-silence, and comes from the most reliable brand in the industry.

If you have the budget for a premium appliance, the Bosch Benchmark SHP9PCM5N is the safest, highest-performing bet you can make for your kitchen.
