How to Install a Dishwasher Under a Quartz Countertop

Kenneth Crawford

Once you have the supply lines, drain line and electrical lines connected on your new dishwasher, the only step left is to install it under the countertop. Most manufacturers pre-install clips on the top of the dishwasher to secure the dishwasher to the countertop, preventing the unit from tipping. Installing a dishwasher under a quartz countertop however, requires side-mount clips to secure the dishwasher to the cabinet frame. Side-mount clips are available from the manufacturer and some appliance repair shops.

Step 1

Attach the side-mounting clips onto the side of the dishwasher. The clips are flat with a hole on one end and a hook on the other end. Slide the hook end into the slots on the side of the dishwasher. Pull the clip toward the front of the dishwasher to firmly engage the hooks.

Step 2

Slide the dishwasher under the quartz counter, ensuring you do not bend any hoses or conduit behind the dishwasher. Open the dishwasher door and take out the bottom dish rack.

Step 3

Place a level across the bottom of the dishwasher tub. Turn the front feet under the dishwasher to lower and raise it as necessary with a wrench until the dishwasher is level.

Step 4

Drill a 1/2 inch deep pilot hole into the cabinet frame on each side of the dishwasher, using the hole in the clip as a guide. The hole on the clip should be against the wood frame of the countertop cabinet.

Step 5

Secure the dishwasher to the cabinet frame with ¾ inch wood screws and Phillips screwdriver.
