Understanding the Basics

Assess Your Space

Before diving into the installation process, take a moment to assess your kitchen layout. Determine the ideal location for your dishwasher, considering factors like proximity to the sink, plumbing connections, and electrical outlets.

To get started, gather the following tools and materials:

Preparing for Installation

Shut Off the Power and Water Supply

Safety first! Turn off the power to the kitchen area from your circuit breaker and shut off the water supply to avoid any accidents during the installation process.

Create a Mounting Bracket

To secure the dishwasher in place, create a mounting bracket using the provided hardware in the installation kit. Make sure it’s level and securely fastened to your cabinets.

Making the Connections

Connect the Water Supply

Carefully connect the dishwasher’s water inlet valve to the hot water supply line. Ensure the connection is secure but not over-tightened to avoid damaging the valve.

Establish the Drain Connection

Attach the dishwasher’s drain hose to the sink’s drainage system or garbage disposal unit. Ensure it’s properly secured to prevent leaks.

Connect the Electrical Wiring

Follow the manufacturer’s instructions to connect the dishwasher’s electrical wiring. If you’re not comfortable with this step, it’s best to hire a professional electrician to ensure safety.

Securing the Dishwasher

Slide the Dishwasher into Place

Carefully slide the dishwasher into its designated space, aligning it with the mounting bracket. Ensure it’s level both front-to-back and side-to-side.

Secure the Dishwasher to the Countertop

Using granite-safe adhesive, secure the dishwasher’s mounting brackets to the underside of the granite countertop. This step is crucial to prevent any tipping or shifting.

Testing and Final Steps

Test for Leaks

Turn the water supply back on and run a short cycle to check for any leaks in the water supply or drainage connections.

Reconnect Power

Restore power to the kitchen area from the circuit breaker and ensure the dishwasher powers up without any issues.
