1. Dishwasher Size and Capacity
The first thing to consider is size. Standard dishwashers are usually 24 inches wide, while compact models measure 18 inches.
-
Families: A full-size dishwasher can handle 12–16 place settings—ideal for households with kids.
-
Small kitchens: Compact dishwashers save space but still offer plenty of cleaning power.
-
Flexibility: Adjustable racks and foldable tines let you fit larger pots and pans with ease.
2. Energy Efficiency Ratings
Energy-efficient dishwashers save money and protect the environment.
-
Look for ENERGY STAR® certification to guarantee lower energy and water consumption.
-
Over a decade, energy-efficient models can save you hundreds of dollars on utility bills.
-
Many now include eco-friendly wash cycles that use less water for lightly soiled loads.
3. Noise Level in Dishwashers
Noise level is measured in decibels (dB), and it makes a big difference in open-concept homes.
-
38–45 dB: Whisper-quiet, perfect for kitchens near living rooms.
-
46–50 dB: Quiet but noticeable.
-
51+ dB: Louder, suitable for closed-off kitchens or basements.
If you cook and entertain in the same space, invest in a quieter model.
4. Wash Cycles and Settings
The right wash cycles give you flexibility for different cleaning needs.
-
Quick Wash: Great for lightly soiled dishes.
-
Heavy Duty: Designed for pots, pans, and baked-on messes.
-
Sanitize: Uses high heat to kill bacteria—ideal for baby bottles or cutting boards.
-
Auto Sensors: Adjust time and water based on how dirty the dishes are.
5. Smart Features and Connectivity
Modern dishwashers can now connect to your smart home.
-
Wi-Fi controls let you start or monitor cycles from your phone.
-
Voice assistants like Alexa and Google Home can integrate with certain models.
-
Custom alerts notify you when a cycle is done or detergent is low.
While not essential, these features add convenience for busy households.
6. Dishwasher Durability and Build Quality
A dishwasher is an investment—you’ll want it to last.
-
Stainless steel interiors resist odors and stains better than plastic tubs.
-
Nylon-coated racks are more durable than vinyl-coated racks.
-
Check brand reputation and warranty coverage for extra peace of mind.
7. Water Usage and Efficiency
Efficient dishwashers use less water without sacrificing performance.
-
Modern units average 3–4 gallons per cycle, compared to older models using up to 10.
-
Some feature eco-wash settings that further reduce water consumption.
-
If you live in an area with high water costs, this can be a major money-saver.
8. Price and Warranty Options
Dishwashers can range widely in cost, so it’s important to set a budget.
-
Budget-friendly models ($400–600): Fewer features but get the job done.
-
Mid-range models ($700–1,000): Best balance of price and performance.
-
Premium models ($1,200+): Quietest operation, smart features, and premium finishes.
Always compare warranty coverage—one year is standard, but some brands cover up to 10 years on certain parts.
9. Installation and Space Requirements
Before you buy, make sure your kitchen is ready for the new appliance.
-
Measurements matter: Height, width, and depth must fit your cabinetry.
-
Door clearance: Ensure there’s space to open the dishwasher fully.
-
Installation: Some models are DIY-friendly, but built-ins often require professional installation.
10. Brand Reputation and Customer Reviews
A dishwasher may look great in the store, but customer experience tells the real story.

Check reviews and ratings to learn about noise, cleaning performance, and reliability.
