Choosing a Replacement Dishwasher

Make sure you’re choosing one that is compatible with your kitchen to avoid mishaps when it’s time to replace this appliance. Here are some things to consider when choosing a new dishwasher.

• Size: Making sure your new dishwasher will fit into the space where your current one is, is super important. The most common dishwasher sizes are 18" and 24" wide, so chances are you will be choosing one of those, but it’s best to measure to be sure. Check out our guide on How to Measure a Dishwasher.

• Compatibility: Make sure you’re purchasing a dishwasher with compatible voltage. Standard dishwashers in the US require a 120V while some European models require 220V or 240V. You can double-check voltage requirements in the product specifications before you make your purchase. If you’re looking for something sustainable, look for energy-efficient models.

• Features: If you’re going to switch out your dishwasher, why not make it an upgrade? Some dishwashers have features that make sense for your lifestyle and will make doing the dishes even easier. Choose from helpful features such as hard food disposal, Wi-Fi connection, and a third rack for larger wash capacity.

• Sound Ratings: You may want to pay attention to sound ratings when choosing a model. Sound ratings will tell you how loud your dishwasher will be when you use it. If you are a renter with neighbors above or below, or have a new baby in the house, you may want to prioritize a quiet model to keep the peace.

How to Replace a Dishwasher

You'll Need:

• Screwdriver/drill
• Screws
• Wrench
• Bucket
• Drop cloth/old towel

1. Turn Off Power & Water

Before replacing a dishwasher be sure that the power is turned off. Unplug the old dishwasher or and turn off the circuit breaker. Once the power is off, shut the water supply off by closing the valve or turning the house water off and opening the faucet until water stops flowing. Take note of where your drain and water hose connect, then disconnect the drain and water hoses from your old dishwasher and allow them to drain into a bucket.

2. Detach Your Old Dishwasher

Once you're prepped and ready to go, grab your screwdriver and unscrew your old dishwasher. There may be screws connecting it to cabinetry and/or the countertop.

3. Swap Out Dishwashers

Use a drop cloth or old towel to make it easier to move your old dishwasher out and your new dishwasher in. Place the feet of the old dishwasher onto the drop cloth so you can slide it out of its space more efficiently. Remove your old dishwasher from the area so you can make room to bring your new one in.

4. Adjust Your New Dishwasher

Bring your new dishwasher in front of the space it's going to go by sliding it with your drop cloth. Adjust the feet so that it will fit into the space with minimal gaps. Once you've adjusted the feet, replace and fasten the water and drain hose to their respective places – have your wrench handy. Then, plug in your new dishwasher, but refrain from sliding it back into place yet.

Tip!

When replacing your drain hose, be sure that it is shaped in an arch to prevent water build-up that could damage your appliance in the future.

5. Test Your Dishwasher

Test out your dishwasher by turning the power and water back on and running it. Check for leaks or improper drainage and make adjustments as necessary. Once you determine your dishwasher is running smoothly, slide it into place carefully, while avoiding bends in the hoses.

6. Secure Your New Dishwasher

Your dishwasher may need more adjustments to its feet to fit into the space and blend seamlessly with the cabinets or drawers — once you have it adjusted to your liking, use screws to keep your dishwasher in place.
