Step by Step Process

1. Firstly, you need to cut off the water supply from the entire house.

2- Open the inside panel of your dishwasher to have access to your power cord, drain outlet and   inlet tubes and valves.

3- Put your dishwasher underneath the cabinets and use a marker to highlight the cords locations for your drilling process.

4- Use your power drill to make holes the same size of the cords that will pass through it; around 1½-inch.

5- Slide your dishwasher under its designated place and run the cords through the hole and make sure there are no tangling in cords.

6- This step is very crucial! You need to level your dishwasher carefully so that it stays flat while the door is open. Test that it fits the space smoothly by opening the door and closing to make sure it does not bump into the countertop or the cabinets.

7- Now you need to securely mount your dishwasher into your countertop. There are lots of mounting kits that can be purchased; you can check with your supplier about that! The dishwasher needs to be mounted professionally since it cannot be attached directly to a granite worktop as drilling or screwing through a granite surface can lead to it being chipped and damaged. Therefore, ask your supplier for a solution or seek professional help to avoid any casualties.

8- An alternative solution to a mounting kit would be a wooden strip which you can attach directly underneath your countertop. This will allow you to secure the dishwasher into this wooden stripe instead of drilling through your granite surface and risk damaging it. With the use of the construction adhesive, you can attach the wooden stripe to the worktop and then drill through the wooden surface to secure the dishwasher without any harm done to your granite top.

9- Then, you need to connect the dishwasher outlet and drain line with your main drain pipeline. You will need to put a drain tailpiece with an inside inlet. By using hose clamps; join the dishwasher’s outlet and drain line together. Another hose should connect your dishwasher to the inside inlet in your sink.

10- Connect your power cord to your power supply box. Make sure you to connect each color of wire together with its pair through using wire nuts and then plug your cord into your electrical outlet.

11- Turn the water supply back on and test your dishwasher to make sure it is working efficiently
