Materials needed to install a dishwasher

We offer free estimates and service in the Northern Georgia area. Some localities require a dishwasher air gap. Dishwasher air gaps prevent cross-contamination with waste. To install this, connect the air gap to your dishwasher drain hose or garbage disposal. Then, push the air gap through the hole in your counter. Your email address will not be published.

You can do this from your circuit breaker. We recommend using a voltage detector to confirm that it is off.

Then, turn off the water supply with your shut off valve. This is located beneath your sink. You can then use a screwdriver to remove the front access panel near your floor. Some water might leak out once you do this, so we recommend having a bowl handy to collect any water. The next thing to disconnect is the drain hose.

These mounting brackets are what keep your dishwasher in place along with your cabinets and countertops. Now, you are ready to remove your old dishwasher! We recommend placing down some cardboard or a sheet so you can protect your floor. Then, remove your old dishwasher.

Installing the Water Supply Valve First, disconnect the previous supply line from the shutoff valve. Locate the hole between your dishwasher and the kitchen sink cabinets.

Route your new supply line through the hole in the sink cabinet. Secure it to the floor with tape so it stays in place when you add the new dishwasher.

Connect the shut off valve and the new water supply line. Locate the hole between your dishwasher and the sink cabinets. Route your new drain hose through the hole in the sink cabinet. Remove the dishwasher from the box and lay it on its back to look at the connection areas underneath.

Remove the cap over the drain line connection your instructions will tell you precisely where to find it and attach it to the drain hose. You will want to use a small hose clamp to be sure it is securely in place. Thread your drain hose through the hole connecting to your sink so it can be attached later. Now, slide your dishwasher into its cabinet space. Use a wrench to adjust the height of the dishwasher legs to fit flush with the countertop above it.

The dishwasher 90 is a small, 90 degree angled elbow fitting that allows the water line to lie flat rather than bending at an angle. You will attach this fitting to the dishwasher water valve or line located under the washer. Now, the wires that carry power to the dishwasher need to be connected. Before you do this step, verify again that your power is still off at the breaker level. If your dishwasher spot already has power, find the wires from your junction box and put them in place.

Some professionals recommend wrapping them with electrical tape as well. As you do this, match all your connections — white with white, green to green, etc. Finally, put the copper ground wire under the round green screw and tighten it up.

Once all the connections are secure, screw the junction box back in place. Remember when you threaded the new drain hose through the opening that leads to the cabinet under the sink?

Under your sink, you probably have a sink tailpiece. Your drain hose will fit onto the branch that comes off the pipe. Use a clamp to securely connect it to the sink tailpipe or the disposal, depending on your preference. Your drain hose is connected, your water line, your power, and the dishwasher are securely in place.

You can turn the water valve back on to see if you notice any leaks. You may need to re-clamp a hose or check the connections at the bottom of the dishwasher if you see a leak. You can secure the dishwasher to the countertop with screws through the mounting brackets if there are no leaks. Turn the power back on at the breaker, and your dishwasher is ready to use! It generally takes about an hour to an hour and a half to install a dishwasher. This depends on your expertise and familiarity with the different fittings and pipes below your sink.

If you have to remove a cabinet to create a space for the dishwasher, it will take longer. The temperature of the water in your dishwasher is essential. You can check your hot water heater to see what the maximum hot temperature is in your home. A dishwasher needs water that is at least degrees Fahrenheit. B ut is should be no higher than degrees Fahrenheit. This supply tube is really nothing more than a longer version of the same kind of supply tubes that feed sink faucets and toilets, so if you've worked on those plumbing fixtures, you'll have no trouble with the dishwasher hookups.

Hooking up the water supply tube to the dishwasher usually requires attaching a special brass fitting known as dishwasher 90 —a degree elbow that allows the supply tube to easily connect to the dishwasher. This fitting is normally included with the connection kit that also includes the braided steel supply tube.

Connecting the drain hose on a dishwasher is an equally simple plumbing job. The drain hose connects to the drain trap under your sink; on the way to the trap, it either loops up to the underside of the countertop under the sink or is attached to an air-gap fitting.

The proper method of doing this depends on the code requirement in your area, but either method is intended to keep dirty wastewater from siphoning back into your dishwasher. As the drain hose loops back down, it is attached either to a nipple on the garbage disposal or directly to a nipple on the sink drain tailpiece. Most of the working parts—both the electrical hookups and the plumbing connections—are located behind an access panel located on the front bottom of the dishwasher.

While it is possible to make these connections while you crouch or lie on the floor, most people find it easiest to carefully lay the dishwasher on its back to remove the access panel and make the preliminary connections. Start by removing the bottom access panel on the dishwasher.

Visually identify the power cord connection fittings, the water inlet solenoid valve, and the drain fitting. Remove the cover on the wire connection housing.

Thread the power cord into the housing, and make the three wire connections: green wire from the appliance cord to the green grounding screw, white neutral wire to white dishwasher lead, and black hot wire to black dishwasher lead. These connections are normally made with twist-on wire connectors wire nuts , but some appliances may have different methods for making the wire connections.

Replace the cover on the wire connection housing. Your dishwasher connector kit includes a 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 water inlet fitting on the solenoid valve.

Apply some pipe joint compound to the threads of the dishwasher 90 fitting, then thread it onto the solenoid valve. The dishwasher connector kit also includes a braided steel water supply tube. Thread the coupling nut of the supply tube onto the dishwasher 90 fitting, and tighten with channel-lock pliers or an adjustable wrench. This is a compression fitting that does not require pipe joint compound. Be careful not to overtighten, as it is possible to strip the threads.

Turn the dishwasher right side up. Slide the dishwasher into place under the kitchen counter, feeding the power cord, the water supply tube, and the drain hose through the holes in the sidewall of the cabinet.

Line the appliance up to the center of the opening without pushing it too far back.
