The Complete Guide to Installing a Dishwasher in Your Existing Kitchen

Adding a dishwasher to your kitchen can make cleaning up after meals a breeze. But installing a dishwasher in an already built-out kitchen requires careful planning and execution. This comprehensive guide covers everything you need to know, from picking the right dishwasher model to modifying your existing cabinetry and countertops to accommodate your new appliance.

With some strategic thinking and skilled labor, you can integrate a dishwasher into your kitchen in a way that maximizes function and aesthetics. Follow the steps below to upgrade your kitchen with sparkling clean dishes.

Dishwasher Types

The first decision is selecting what type of dishwasher best suits your needs and kitchen layout.

Built-in Dishwashers

Integrated dishwashers install flush with surrounding cabinetry for a seamless look. The control panel is concealed for a discreet appearance. Semi-integrated models have a control panel that remains visible. Standard built-in dishwashers fit in between existing cabinets with access to controls on the front.

Portable Dishwashers

Countertop and freestanding portable dishwashers sit on the kitchen counter or floor and hook up to the sink faucet when in use. These are quick and easy to install, but take up valuable counter or floor space.

Specialty Dishwasher Designs

Slimline or narrow dishwasher models are ideal when space is limited. Dishwasher drawers install under the counter with each drawer operating independently for small loads. Pull-out dishwashers tuck away under counters and can be deployed when needed to maximize floor space.

Determining Placement

Carefully measure your kitchen to identify the best spot for your dishwasher.

Measure Available Space

Most standard dishwashers require a width of 24 inches and a height of approximately 34-35 inches. This minimum clearance must accommodate plumbing and electrical connections located at the rear. If your kitchen is tight on space, look for narrower, compact models.

Modifying Cabinets

If no 24-inch gap exists, you may need to remove a cabinet section and rework surrounding cabinets to create the necessary opening. Consult a kitchen designer or contractor to modify existing cabinetry.

Adjusting Countertops

Your countertop may need its height altered to align with your dishwasher for a flush fit. Also account for clearance around any control panel or handles that will be installed.

Installation Process

Proper installation is key to getting optimal dishwasher performance. Pay close attention to the following steps.

Electrical Requirements

Dishwashers are either wired directly or plug into an outlet. Using an existing nearby outlet is easiest, otherwise plan for installing a new 120-volt outlet.

Plumbing Connections

The dishwasher drain hose connects to the sink drain, disposer or dedicated branch tailpiece. Use a dishwasher drain connector kit for secure, leak-proof fitting. The dishwasher also connects to the hot water supply line.

Mounting and Securing

After feeding hoses and wires through, slide your dishwasher into place. Level it, anchor to underside of counter, then install kickplate. This prevents movement and vibrations.

Countertop Modifications

For built-in models, make necessary cut-outs in your countertop for controls to poke through. Adjust countertop height so dishwasher top is flush.

Efficiency Considerations

Pick an ENERGY STAR certified dishwasher to save on electricity and water bills. Also look at the WELS rating, with more stars indicating better water efficiency.

Additional Features to Look For

Consider dishwashers with drying systems like fan-assisted drying for dryer dishes. Look for adjustable racks, fold-down tines, and wash options like delicate, sanitize, and quick washes.

Final Steps

With installation complete, do a test run to catch any leaks or issues. Make sure the dishwasher is level, drains properly and cleans dishes well. Refer to your manual for cleaning and maintenance recommendations.

Transforming your kitchen to add a convenient dishwasher takes planning and skill. But the benefits of reduced cleanup time can make the project well worth the effort. Follow this guide for key steps like measuring your space, modifying cabinetry, proper installation and choosing the best dishwasher for your needs.

You can integrate a dishwasher into your kitchen with some remodeling. The result will be a kitchen upgraded with sparkling clean dishes.
