How to Install a Garbage Disposal
Learn how to install a new garbage disposal under a kitchen sink with these step-by-step instructions.
Take the new dishwasher out of the box and lay it face down so the back is visible.
Verify that all of the connections are there.
Take the cap off the drain line connection at the dishwasher.
Note: Don't be alarmed if water comes out, each unit is tested at the factory before it's shipped.
Attach the drain line to the dishwasher.
Using pliers, crimp the clamp around the hose to secure.
Thread the drain line into the hole under the sink.
Slide the new dishwasher under the countertop.
Level the countertop by adjusting the height of the legs with a wrench.
Secure the dishwasher to the countertop with screws.
Note: Verify the power is still off at the breaker.
Re-attach the wires of the same color, then screw on wire nuts and wrap with electrical tape.
Place the copper ground wire under the green-round screw, then tighten down.
Attach the dishwasher supply line to the 'dishwasher 90', then tighten with a wrench.
Note: New dishwashers will include all the parts you need to install with the exception of the 'dishwasher 90'. You'll need to purchase this at your local home improvement store.
Turn on the water under the sink.
Attach the drain line to the plumbing system, then tighten the clamp around the hose.
