How to Choose a Dishwasher: A Complete Buying Guide

A dishwasher is one of the most frequently used appliances in many kitchens, so choosing the right one involves more than simply finding a model that fits the available space.

Size, interior capacity, noise level, wash options, drying performance, and rack configuration can all affect how well a dishwasher works for your household.

If you're shopping for a new dishwasher, this guide covers the most important things to consider before making your decision.

1. Start With the Right Dishwasher Size

Before comparing features, make sure the dishwasher will actually fit your kitchen.

Many built-in dishwashers are designed for a standard-width opening, but dimensions can vary between models. Measure the available width, height, and depth carefully rather than assuming every dishwasher will fit the same opening.

You should also review the manufacturer's installation specifications for the individual model you're considering.

If you're replacing an existing dishwasher, don't rely only on the dimensions of your old appliance. Measure the actual opening again before ordering.

2. Consider Your Household and Capacity Needs

The right dishwasher capacity depends on how your household uses the kitchen.

A household that cooks frequently or regularly uses large pots, pans, and serving dishes may have different needs from someone who primarily washes plates, glasses, and smaller items.

Instead of focusing only on stated capacity, look closely at the interior rack configuration.

Consider questions such as:

• Are the racks adjustable?
• Is there room for taller glasses or larger plates?
• Can the layout accommodate pots and pans?
• Is there a third rack for utensils or smaller items?
• Can sections of the rack be repositioned or folded?

A flexible interior can sometimes be more useful than capacity numbers alone.

3. Pay Attention to Dishwasher Noise Levels

If your kitchen is open to your dining or living area, dishwasher noise can be an important consideration.

Dishwasher sound levels are commonly measured in decibels (dBA). In general, a lower dBA rating indicates quieter operation.

The importance of noise level depends on your home's layout and when you typically run the dishwasher. A quieter model may be particularly appealing if you entertain frequently, run the dishwasher at night, or spend a lot of time near the kitchen.

When comparing models, check the manufacturer's listed sound rating rather than assuming that all newer dishwashers operate at the same noise level.

4. Compare Wash Cycles and Cleaning Options

Dishwashers can offer anything from basic everyday cycles to a variety of specialized cleaning settings.

Depending on the model, you may encounter options designed for:

• Everyday loads
• Heavily soiled cookware
• Delicate items
• Quick washing
• Energy-efficient cleaning
• Sanitizing or high-temperature washing

More cycles aren't necessarily better.

Think about which settings your household would actually use. A smaller selection of useful cycles may be more valuable than numerous specialized settings that rarely leave the control panel.

5. Look at the Drying System

Cleaning is only part of a dishwasher's job. Drying performance can also affect the everyday experience.

Different dishwasher models use different approaches to drying, and performance can vary depending on the appliance, selected cycle, and type of items being washed.

If avoiding wet dishes is particularly important to you, review the drying features and cycle options of the individual models you're considering.

Also remember that some materials—particularly certain plastics—can be more difficult to dry completely.

6. Check the Rack Configuration

Dishwasher racks can make a surprisingly large difference in everyday use.

Look for a configuration that works with the dishes and cookware you regularly wash.

Features worth considering can include adjustable upper racks, folding tines, dedicated utensil storage, and third racks, depending on the model.

For example, an adjustable rack may make it easier to accommodate tall glasses one day and larger dishes the next.

Don't choose based solely on the number of racks. Consider how usable the entire interior will be for your household.

7. Consider the Control Location

Dishwasher controls may be located on the front of the door or along the top edge.

Front controls are generally easy to see and access when the dishwasher is closed.

Top controls can create a cleaner, more streamlined exterior because the controls are less visible when the door is shut.

Neither design is inherently better. This choice largely comes down to your preferred appearance and how you like to interact with the appliance.

8. Think About Finish and Kitchen Design

Because a dishwasher sits alongside your cabinetry, its appearance can affect the overall look of your kitchen.

Consider how the finish coordinates with your refrigerator, range, oven, range hood, and other appliances.

You don't necessarily need every appliance to be identical, but thinking about the kitchen as a whole can help create a more cohesive design.

9. Don't Forget Installation Requirements

Before ordering a dishwasher, review its installation requirements carefully.

Depending on your kitchen and the appliance, installation considerations can include the electrical connection, water supply, drain connection, and available cabinet opening.

If you're replacing an existing dishwasher, don't automatically assume the new appliance has exactly the same installation requirements.

Always review the specifications and installation documentation for the individual model.

10. Compare the Features You'll Actually Use

It's easy to become distracted by a long list of features when shopping for appliances.

Instead, focus on what will make a difference in your kitchen.

For one household, that might be quiet operation. For another, it could be adjustable racks, specialized wash cycles, drying performance, or interior flexibility.

Ask yourself:

Will I actually use this feature regularly?

If the answer is no, it probably shouldn't be the deciding factor in your purchase.

Dishwasher Buying Checklist

Which Dishwasher Is Right for You?

There isn't one dishwasher that's right for every kitchen.

The best choice is a model that fits your space, accommodates the dishes you regularly use, and provides the features that matter to your household.

Start with dimensions and installation requirements. Then compare capacity, rack design, noise level, cleaning options, and drying features.

Taking a little time to compare these details can help you choose a dishwasher based on how you'll actually use it—not simply on the longest feature list.
