How to Remove a Built-In DishwasherThe first thing you need to do is shut off the water and the electrical break powering the appliance. Next, gather your supplies and tools. These include an old blanket or drop cloth, a couple of adjustable wrenches, a screwdriver, pliers, a pan, a sponge, bucket, and towels.
Removing an undercounter dishwasher and replacing it will take an experienced installer less than an hour. You probably won’t manage the job that quickly, but it is a relatively simple procedure, especially because the plumbing and electrical hookups are already in place. And by doing the work yourself, you can save the $100 or more a retailer will charge, or step up to a model with more features. — This Old HouseWhen you have your tools and supplies ready, put them on the counter near the dishwasher for quick access; then, place an old blanket or drop cloth in front of the appliance. Now, you’re ready to remove your built-in dishwasher by following these steps:
- Using a screwdriver, remove the front, bottom panel to expose the water supply line (it will likely be flexible copper or a stainless steel line).
- Place a pan under the line and then use a wrench to unfasten the water supply. The pan will catch any drips as you loosen the water line.
- Open the cabinet doors directly under the kitchen sink and find the drain line running from the dishwasher.
- Place a bucket directly under the drain connection, then unfasten the inlet arm coming from the appliance.
- Unfasten the retaining screws located under the lip of the counter.
