We didn’t realize how much we used our dishwasher until it stopped working because it’s an appliance we took for granted. It’s a workhorse in most kitchens, and when it stops operating and a repair doesn’t solve the problem, it’s not a difficult decision to choose between doing without or replacing it. When you’re choosing to replace a dishwasher look for one the same size of the unit you’re replacing so you choose one with the same electrical and plumbing connections so new work isn’t required.

A plumber will charge $1,520, which includes labor and material, and removing the old unit. If you’re handy and want to struggle getting the old one out, and have plumbing and electrical experience and tools, you can make the swap for $1,200, the cost of the appliance, and save 21% by doing it yourself.

This is not a trivial job. You will need basic tools such as adjustable wrenches, screwdrivers, pliers, a level and a tape measure. Have a bucket and sponges nearby to catch water as you disconnect the old unit. Lay an old rug in front of the unit to protect the floor. Remove the doors of the base cabinets on the sides of the appliance and empty them so you can work under the sink to make the drain connections. Before you start, turn off the water at the shutoff valve and turn off the power to the old unit at the main electrical panel or unplug it under the sink.

You might have a problem if new flooring was added to raise the level of the floor in front of the dishwasher, because carpentry work is needed to adjust the unit to fit. Our best advice is hire a pro who has the skills, tools and experience to do the job.
