Dishwasher Buying Guide
1. Types of Dishwashers
Front Control Dishwashers
Before buying a new dishwasher read our dishwasher buying guide for expert tips on choosing the dishwasher for your home.
Design:Front control dishwashers have their buttons and display panel on the front of the door, making them easy to see and use.
Best For: People who want simple, fast access to controls and a classic look.
Pros
Controls are visible and easy to reach
Often less expensive than top control models
Quick to start or pause a cycle
Cons
Can look less sleek than top control models
Buttons may be bumped accidentally
Top Control Dishwashers
Design: Top control dishwashers hide the buttons along the top edge of the door. You only see the controls when you open the door, giving the front a smooth, modern look.
Best For: People who like a clean, stylish design and want to prevent accidental button presses.
Pros
Sleek, seamless appearance
Controls are hidden from kids
Often comes with more advanced features
Cons
Must open the door to view or change settings
Usually a little more expensive
Dishwasher Drawers
Design: Dishwasher drawers pull out like kitchen drawers and come in single or double drawer models. Each drawer works independently.
Best For: Small households, people who wash small loads often, or kitchens with limited space.
Pros
Can run one drawer at a time to save water and energy
Easy to load without bending over
Great for open-concept kitchens (very quiet)
Cons
Smaller capacity than traditional models
More expensive per cubic foot of space
Not ideal for large families or heavy dish loads
2. Sizing and Installation Requirements
Before making your decision, make sure it fits in your setup.
Standard Dishwasher Sizes
Standard dishwashers: 24 inches wide, 24 inches deep, and 34-35 inches tall.
Dishwasher drawers: 24 inches wide, 22-24 inches deep, and 16-18 tall for single drawers or 32-34 tall for double drawers
Compact dishwashers: 18 inches wide, 22-24 inches deep, and 32-34 tall
Types of Installations
To install a dishwasher, you'll need a hot water supply line, a drain connection, a power source (either a standard outlet or hardwiring), and for built-in models, mounting brackets and space under the counter—while portable and countertop dishwashers also require a faucet adapter and access to a sink for water and drainage.
Measure your space
Measure doorways, hallways, and the appliance location carefully.
3. Key Features to Consider
Today’s dishwashers offer more than just basic washing capabilities. Depending on your budget, you might want to consider these special features
Wash Cycles
Different settings for normal, heavy, quick, eco, and delicate loads.
Adjustable Racks
Moveable or foldable racks to fit large pots, tall glasses, or oddly shaped items.
Third Rack
A shallow top rack for utensils, lids, or small items, freeing up space below.
Soil Sensor
Automatically adjusts the cycle time and water usage based on how dirty the dishes are.
Drying Options
Includes heated dry, fan-assisted dry, or auto-open door drying to reduce moisture.
Noise Level
Measured in decibels (dB); quieter models are under 50 dB and good for open kitchens.
Stainless Steel Tub
More durable and quieter, but it also resists stains, helps dishes dry faster, and is more hygienic since it’s less likely to harbor bacteria, viruses, or bugs compared to plastic tubs.
Delay Start
Lets you run the dishwasher at a later time, useful for off-peak energy hours.
Energy Star Certified
Uses less water and electricity, saving money over time.
Smart Features
Wi-Fi enabled models allow remote control, cycle tracking, and maintenance alerts.
ADA Height
Shorter, accessible models designed to fit under lower counters and meet ADA compliance for easier use.
Third Rack
A shallow top rack that provides extra space for utensils, lids, and small items, freeing up more room in the lower racks.
Fourth Rack
An additional flexible rack (available in some premium models) for even more loading options, perfect for silverware, flat tools, or delicate items.
