Best Quiet Dishwasher: What to Look For and How to Choose

A quiet dishwasher is one of the most requested features — especially in open-plan homes, apartments, and households with young children or light sleepers. Here's everything you need to know about dishwasher noise levels and how to choose the quietest model for your needs.

How Dishwasher Noise Is Measured

Dishwasher noise is measured in decibels (dB). Here's a practical reference:

• Under 40 dB: Near silent — quieter than a library
• 40–44 dB: Very quiet — you can have a normal conversation nearby
• 44–50 dB: Moderate — noticeable but not disruptive
• 50+ dB: Loud — similar to a normal conversation or rainfall

To understand what noise level is acceptable in your space, measure your kitchen's ambient noise with a TopTes TS-501B Decibel Meter (amzn.to/49igwFb). It has a 2.25" backlit LCD screen, A/C weighted measurement, and a 30–130 dB range — perfect for comparing your kitchen's baseline noise to a dishwasher's rated dB level.

What Makes a Dishwasher Quiet?

• Insulation: More insulation around the tub absorbs sound
• Motor type: Brushless motors run quieter than older brush motors
• Stainless steel tub: Absorbs sound better than plastic tubs
• Anti-vibration mounts: Reduce vibration transferred to cabinets and floors
• Soft-close door: Reduces door slam noise

Noise Level Targets by Situation

Quietest Dishwasher Brands

Bosch (Industry Leader)

Bosch is widely regarded as the quietest dishwasher brand. Their 300, 500, and 800 series models operate at 44 dB, 44 dB, and 42 dB respectively. The 800 series at 42 dB is among the quietest dishwashers available at a non-luxury price point ($900–$1,300).

Miele

Miele dishwashers are premium-priced ($1,200–$2,500+) but offer exceptional quietness (38–42 dB) and longevity. Built to last 20 years.

LG and Samsung

Both brands offer quiet models in the 44–48 dB range at mid-range prices ($600–$1,000). Good value for open-plan kitchens.

Whirlpool and KitchenAid

Mid-range options at 47–50 dB. Good for standard kitchens where some noise is acceptable.

Features Worth Paying For in a Quiet Dishwasher

• Stainless steel tub (better sound absorption than plastic)
• Third rack (more loading flexibility without overloading)
• Soil sensor (adjusts cycle automatically — avoids unnecessarily long, noisy cycles)
• Delay start (run overnight when noise doesn't matter)

Keep Your Quiet Dishwasher Running Quietly

Even a quiet dishwasher gets louder when it's dirty or has a clogged filter. Run a monthly cleaning cycle with Affresh Dishwasher Cleaner Tablets (amzn.to/42P5MKQ) to keep the pump and spray arms clear. Use Finish Powerball Dishwasher Pods (amzn.to/3RE929j) for reliable everyday cleaning, and Amazon Basics Rinse Aid (amzn.to/4v4Ts5b) for spot-free drying.

Bottom Line

For most open-plan homes, a Bosch 300 or 500 series at 44 dB offers the best balance of quietness, features, and price. For the absolute quietest experience, the Bosch 800 series (42 dB) or a Miele (38–42 dB) is worth the premium. Use a decibel meter to measure your space and set realistic expectations before buying.
