Tools and Materials
Before getting started, it is a good idea to collect the necessary tools and materials. The more prepared you are, the more efficient you will be.
Tools :
- Adjustable wrench.
- Screwdrivers (Phillips and flathead).
- Drill, and bits if necessary.
- Measuring tape.Bucket or towels.
- Level.
Materials:
- Teflon tape.
- Wire connectors, and electrical tape if necessary.
- Dishwasher installation kit (Typically includes a drain hose, water supply line, and fittings).
You may be able to pick most of these items up at your local hardware store, or they may have come with your dishwasher.
Step 1: Measure the AreaPrior to buying or installing your dishwasher
Determine if it will fit into the area designated for it. Standard dishwashers are usually 24 inches wide, so measure these things, to be sure:
Width: Measure the width of the cabinet opening.
Height : Measure the distance from the floor to the bottom of the countertop.
Depth : Measure the distance from the back wall to cabinet front.
This assures you will not encounter problems. If you are replacing an old dishwasher, it is likely the sizes will be compatible, but it is worth verifying the measurements.
Step 2: Prepare the AreaClean and prepped area is important for a smoother installation.
Before proceeding with the installation, follow these steps to get your area ready:
Turn Off Utilities: Make sure to turn off the water shut off valve (under the sink) to protect against leaks.Then turn off the power at the circuit breaker for safely avoiding electrical hazards.
Clear the Area: It will be helpful to remove all items under the sink and/or surrounding where the installation will take place.
Inspect Connections: Check to ensure you have a water supply line, drain line, and electrical outlet. If you have any of these items unavailable, a plumber or electrician may need to be scheduled prior to installing.
By taking the time to get this area ready to install will help avoid mistakes.
Step 3: Take Out the Old Dishwasher (If Applicable)
If you are replacing an existing dishwasher, you need to take it out of its space safely, as follows:
- Unhook the water supply line (which may have a compression fitting). You will want a bucket or towels handy to collect any excess water.
- If the dishwasher is installed with an electrical connection instead of a plug, unfasten the electrical wires. Just make sure to note the order of connectors for the new dishwasher.
- Remove the screws securing the dishwasher to the countertop or adjacent cabinetry with the mounting brackets.
- Slide the old dishwasher out of its space, being careful to not bend the water or drain lines.
- Lastly, be sure to recycle the old dishwasher or arrange for it to be picked up by waste management services.
Step 4: Set Up Your New Dishwasher
Now you’re ready to set up the new dishwasher!
Follow these instructions carefully to ensure a successful setup.
Attach the Drain Hose:
Connect the drain hose to the outlet of the dishwasher and secure it with the clamp that came with your new dishwasher.
Thread the hose through the cabinet opening under the sink. Make sure the hose doesn’t have any kinks this will allow water to flow.
Connect Water Supply Line:
Wrap Teflon tape around the threads of the water inlet valve on the dishwasher.Connect the water supply line and tighten using an adjustable wrench until snug, but not too tight.
Electrical Connections:
If your dishwasher plugs into an outlet, plug it into the closest outlet. If your dishwasher is hardwired, do the following :
- Lift up and remove the cover to the junction box on the dishwasher.
- Tighten the wires with the wire connector (black wire to black wire, white wire to white wire, green or bare copper wire to the ground screw).
- Replace the cover plate.
Positioning the Dishwasher:
- Carefully slide the dishwasher into position.
- Adjust the leveling legs to make sure the dishwasher is evenly balanced–this is important to avoid water pooling inside of the dishwasher.
Fasten the Dishwasher:
Use the mounting brackets that come with the dishwasher to secure the dishwasher to the countertop or sides of the cabinet. This ensures that the dishwasher will not tip over while the door is open.
Step 5: Assess the Installation
Before patting yourself on the back for a job well done, let’s run some tests to verify everything is working properly.
Restore Power and Water:
Turn the water supply valve back on and return the circuit breaker to its original position.
Run a Test Cycle:
Run a short wash cycle and observe the dishwasher. Leak check the water supply and drain connections.
Check Performance:
After the test cycle is completed, check the operation of all interior components, such as spray arms. Leaks or other drainage issues are grounds for switching off utilities and double-checking hook ups.
