Can a Countertop Dishwasher be Installed Under a Sink?


EdgeStar Countertop DishwasherOne of the more common questions that I get from customers at EdgeStar Support concerns whether or not the countertop line of dishwashers can be installed under the counter. In this article, I’ll cover the basic setup of the dishwashers in the EdgeStar lineup and answer that question from a technical perspective.

The countertop dishwasher has got to be one of the great inventions of the 21st Century! Easy to install and even easier to operate. It’s a blessing to owners of small kitchens everywhere, and certainly a miracle of technology. It just can’t be beat! Best of all, no complicated plumbing to do…whew…!

All of our compact dishwashers install the same way in just a few simple steps:

  1. Unpack the unit.
  2. Set unit on counter and unpack hoses.
  3. Attach the quick connect to your existing faucet (be sure to remove your aerator).
  4. Connect the lines to the back of the dishwasher.
  5. Plug in the unit to the wall outlet and turn on the water at the faucet.
  6. You’re done! What could be easier?

Now on to the undercounter question…

Portable dishwashers are purposely designed to discourage you from installing it under a sink. We do not recommend installing your countertop dishwasher under a sink and we do not offer any information or help with the matter because if you do attempt to install the unit under a sink and it fails, you will have voided the warranty.

I hope this clarifies the more common questions and simplifies the install of your new dishwasher. Enjoy!
