Single Girl's Guide to Installing a Dishwasher

  • Install kit
  • Teflon tape
  • level
  • measuring tape
  • dishwasher
  • tools; crescent wrenches, screw driver

Step One: Have your new dishwasher ready. And your cell phone, just in case you have to call your Dad.

Step Two: Turn the dishwasher onto it's back so that you can access the electrical and water supply connections. This is the kit for dishwasher installation. Generally about $15.00 at Lowe's or any other home improvement store. It's likely you won't even need all the parts for it. 

Step Three: Access the electrical connection box on the dishwasher and remove the screw to reveal the electrical wires and components. Ground the green ground wire to the green ground screw. Connect the cords from the actual dishwasher with the cord saved from the old dishwasher. You can buy new ones but we reused ours to save a little cash.

Replace the silver box cover to protect the components.

Step Four: Find the water supply connection point. Identify the necessary adapters and fittings from the install kit shown above. The most common is what you see here, the elbow.

Step Five: Wrap the threads of the adapter with three rounds of Teflon tape....

Support the bracket (silver thing beneath the wrench in the picture below) while you tighten the adapter with the wrench. In this case it has to end up pointing to the back of the dishwasher.

Attach the flexi hose from the kit in a similar fashion. Should be your end result:

Step Six: Feed the drain hose and the supply line through the cabinets...

 And the same with the electrical cord. In my case it went over the divider. Be sure to keep the power and the water separate. Safety first!

Step Seven: If there is enough room you can add the old insulation blanket from your previous washer in order to make it even quieter.

Ease the dishwasher slowly into place, be sure to check the gaps on the side as you go.

Step Eight: Measure the gap between the top of the dishwasher and the bottom of the counters. This is too much space, so we have to raise the adjusters in order to bring up the washer.

The gap was created in my case because of the difference in floor height between my tile and where the dishwasher sits. You can see that measured out in this picture:

Step Nine: Using a wonder bar, or some other source of leverage, raise the frame to make it easier to extend the adjusters into position. You want to keep it as even as possible so that you end up with a level dishwasher.

If needed you can add additional leverage to raise the frame.

The tricky part is adjusting the back adjusters properly.

Step Ten: Check to make sure that the dishwasher is level. I have this ever so handy and adorable pink level that my Dad loves to use around the house. :)

Step Eleven: Connecting the water supply to the valve located under the sink. This part was not the most fun, I will warn you. 

Because of the different valve and supply hose sizes, had to make an emergency trip to the hardware store in order to find an adapter that would work with the supply hose. This photo is before adding the Teflon tape to the threads of the fitting, be sure to put teflon tape on all the threads.

 Water supply finished product.

Step Twelve: Connect the new drain hose to the air gap. You may have to cut down the drain hose depending on the size of the fitting. Most disposals require no trimming. We make it difficult in manufactured homes.

Step Thirteen: Check your work. Run a rinse cycle through the washer. Cancel the rinse cycle and make sure that everything drains. You may need to tighten up some of the fittings and that kind of thing to avoid leaks. Recommend putting a pan under the water supply just in case there are any leaks.

  1. THank you for this! i'd love to see it on video, and if you'd show photos at least of otherwise mysterious ingredients here, that would help me, another girl hoping to not need to depend on her husband to get this done! The mystery thing is, "the air gap".


I'd love to hear from you!
Please consider following if you don't already. :)
