A dishwasher is one of the most useful kitchen appliances, saving time, reducing water usage, and ensuring your dishes come out sparkling clean. But with so many models, features, and price points on the market, shopping for a new dishwasher can feel overwhelming. How do you know which one will meet your needs, fit your space, and provide the best value?
This guide will walk you through the key factors to consider when purchasing a new dishwasher — helping you make a smart, informed decision that matches your household’s needs and budget.
1. Know Your Space and Measurements
Before you even start looking at dishwasher models, it’s crucial to know how much space you have.
Measure Carefully
-
Width: Most standard dishwashers are 24 inches wide, but compact models (18 inches) are available for small kitchens.
-
Height and Depth: Measure under-counter space and be sure to account for flooring, cabinet trim, or other factors that could affect fit.
-
Door clearance: Make sure there’s enough room to fully open the dishwasher door without hitting cabinets or appliances.
Having precise measurements ensures you won’t run into installation surprises later.
2. Choose the Right Size and Capacity
Dishwashers come in a range of sizes and capacities.
Standard (24-inch) Dishwashers
-
Fits 12–16 place settings.
-
Ideal for families or households that run frequent loads.
Compact (18-inch) Dishwashers
-
Fits 8–10 place settings.
-
Best for apartments, small kitchens, or couples.
Consider how often you run your dishwasher and how many dishes you typically need to clean. A larger capacity might seem appealing, but if you rarely fill it, you’ll waste water and energy.
3. Evaluate Cleaning Performance
Not all dishwashers clean equally well — and while features matter, the overall cleaning power should be your top priority.
Look for:
-
Spray arms or jets: More spray arms or strategically placed jets improve cleaning coverage.
-
Soil sensors: Adjust water pressure and cycle length based on how dirty the dishes are.
-
Specialized cycles: Heavy-duty or pots-and-pans settings for tough jobs.
-
Filter system: Self-cleaning filters save time, while manual filters may require more maintenance but offer quieter performance.
Reading reviews or consumer reports can give you insight into real-world cleaning results.
4. Consider Energy and Water Efficiency
An energy-efficient dishwasher saves money over time and reduces your environmental impact.
What to Check:
-
ENERGY STAR® Certification: Indicates the appliance meets strict energy and water-saving standards.
-
EnergyGuide Label: Shows estimated yearly energy use and operating cost.
-
Eco Cycles: Offer energy- or water-saving modes for lightly soiled loads.
Efficient dishwashers not only lower utility bills but also align with sustainable living goals.
5. Decide on Noise Level
Noise level can make a big difference — especially if you have an open-concept kitchen or often run your dishwasher at night.
Understanding Noise Ratings:
-
Measured in decibels (dB); lower numbers mean quieter machines.
-
50 dB or higher: Older, louder models.
-
45–50 dB: Standard quiet models; like background conversation.
-
40–45 dB or lower: Whisper-quiet, premium models.
If noise is a concern, prioritize a dishwasher with advanced insulation or brushless motors designed for quiet operation.
6. Select the Features You Need
Modern dishwashers offer a wide range of features — but not every household needs all the bells and whistles.
Popular Features:
-
Adjustable racks and tines: Accommodate larger pots or odd-shaped dishes.
-
Third rack: Provides extra space for utensils or small items.
-
Delayed start: Lets you run the dishwasher during off-peak energy hours.
-
Sanitize option: Uses high-heat rinses to kill bacteria, great for baby bottles or cutting boards.
-
Smart features: Wi-Fi connectivity for remote monitoring, voice commands, or diagnostics.
Focus on features that genuinely improve convenience and performance for your household.
7. Choose the Right Finish and Style
Dishwashers come in a variety of finishes to match your kitchen décor.
Common Options:
-
Stainless steel: Sleek, modern, and durable — but may show fingerprints.
-
White or black: Classic and often more affordable.
-
Custom panel-ready: Allows you to match your dishwasher to your cabinetry for a seamless look.
Also consider handle style (bar, pocket, or recessed) and control placement (front-facing or hidden top control) to suit your design preferences.
8. Check for Durability and Build Quality
A dishwasher is a long-term investment, so durability matters.
What to Look For:
-
Stainless steel tubs: More durable and better at retaining heat than plastic tubs.
-
Reinforced racks: Provide long-lasting support without bending or breaking.
-
Reputable brands and warranties: Check brand reviews and look for a solid manufacturer warranty.
Spending a little more upfront on a well-built model can save you repairs or replacements down the line.
9. Factor in Installation and Delivery
Before finalizing your purchase, consider the logistics.
Questions to Ask:
-
Is installation included, or will you need to hire a professional?
-
Will the store remove and dispose of your old dishwasher?
-
Do you need any extra parts (like hoses or fittings) for installation?
Clarifying these details helps you avoid last-minute headaches or hidden costs.
Pro Tips for Making the Best Choice
-
Read user reviews: See what real customers say about cleaning performance, noise, and reliability.
-
Visit a showroom: If possible, check out the dishwasher in person to test rack adjustability, door weight, and control layout.
-
Stick to your budget: While premium models offer tempting extras, mid-range dishwashers often provide the best balance of performance and value.
-
Plan for future needs: If you plan to grow your family or entertain more often, consider a model with greater capacity.
With thoughtful research, you can feel confident in your purchase and enjoy years of convenient, efficient dishwashing.
