    • New dishwasher
    • Pliers
    • Pipe Joint Compound
    • Dishwasher connector kit – sold separately. Before purchasing this, measure the distance from the dishwasher to the water supply valve to determine what length you need to buy.
    • Electric cord – often sold separately. Look at the dishwasher packaging to determine if you need to purchase an electric cord. If you are replacing an existing dishwasher you may be able to re-use the cord from the old machine.

    Most of the working parts that you will need to access are on the bottom of the dishwasher. To make the work easier turn the dishwasher upside down taking care not to scratch the front.

    Remove the housing for the electric cord to access the wires. Attach the electric cord using wire nuts and electric tape. Replace the electric component housing.

    Note: Always use proper grounding when attaching the electric cord of any appliance.

    Your dishwasher connector kit includes a fitting called ‘dishwasher 90’ that will serve to connect the water supply to the dishwasher. Installing the 'dishwasher 90' is the first step to hooking up the water supply for your dishwasher.

    Locate the dishwasher water inlet. Apply some pipe joint compound to the threads of the ‘dishwasher 90'. Thread the fitting into the dishwasher and tighten using pliers.

    Turn the dishwasher right side up. Slide the dishwasher into place under the kitchen counter. Line it up to the center of the opening without pushing it too far back.

    Use the adjustable legs to raise and level the dishwasher. You can unscrew the legs, with pliers if necessary, to bring the dishwasher up to counter height and level it.

    Connect the end of the water supply line to the water supply valve under the kitchen sink. Turn on the water supply valve and check for leaks.

    Look under the dishwasher at the other end of the water supply line. Check for leaks at the connection with the ‘dishwasher 90’. This is the ideal time to repair any leaks before water damage can occur.

    Locate the rubber tube, the drain line, coming from the dishwasher. Attach the end of the drain line to drain inlet and fasten the drain line with a hose clamp.

    Often the dishwasher will be tied into to the air gap at the kitchen sink. Alternatively, it can be connected to the garbage disposal or the sink drain line directly.

    Lastly, plug in the dishwasher’s electric cord. Before putting the face-plate on the front of the dishwasher, test it. Run the dishwasher through a full cycle making sure that it is taking in and draining water properly. Check once again for leaks under the dishwasher and under the kitchen sink.

    The final step is to put the face-plate on the bottom front of the dishwasher.
