How Does A Dishwasher Hookup To Water
The water-supply connection is an easy matter of connecting one end of a braided steel supply tube to the water inlet valve on the dishwasher and the other end to a shut-off valve on a hot-water supply pipe.
Where is the dishwasher water supply?
Incoming water supply to the dishwasher is usually located under the kitchen sink. Locate the hot water supply under the sink, look for a pipe that branches off towards the direction of the dishwasher.
What water connections do you need for a dishwasher?
Water supply: A dishwasher needs hot water. The closest source is the hot water supply under the sink. Replace the shutoff valve with a new one that connects both the sink and the dishwasher to the hot water line.
What To Do Before Installing A New Dishwasher For The First Time
There are lots of rules you need to be aware of when installing a dishwasher for the first time. Because dishwashers use both water and electricity, the risk of a catastrophic outcome should something go wrong is much higher than for most other appliances the rules exist to keep you, your home, and everyone else safe.
Dishwasher installation tools
As well as the tools needed for a replacement installation, you’ll need a couple of other things:
- A drill, hole saw or other means of making a 100 x 150mm hole in the side of your cabinetry
- A crowbar or similar for removing cabinetry
- Sealant for protecting your benchtops from steam and water damage
- A brush or roller to apply the sealant
- A new tap connection
- A new drain connection with an attachment for the dishwasher drain hose
- A new power outlet and the right cabling.
Your plumber and electrician will probably be able to supply the last three items.
Getting started
Under the Building Code of Australia, power points and water pipes can’t be installed in the same cabinet void as your dishwasher instead, your drainage, power and water supplies must be installed in the next cabinet along, with hoses and cables passing through a small hole to the appliance. Ever wondered why your dishwasher’s plug is under the sink, not behind the appliance? It’s to reduce the risk of electrocution if it springs a leak.

Wrong Side Of The Trap
The first problem is the dishwasher drain is connected to the sewer side of the trap. Water always sits in the bottom of the P-trap, and this prevents sewer gases from coming into the house. The dishwasher drain must be connected before the P-trap, not after it, which is what was done here. With this improper installation, sewer gases have the potential to come back into the dishwasher. The diagram below right shows a proper installation.

Attach Water Supply Line
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.

What To Consider Before Installing Your Dishwasher
The Bosch 800 Series SHPM88Z75N is the best dishwasher you can buy.
Before you get your new dishwasher, youll want to make sure your kitchen is fully prepped to have the new dishwasher delivered . Start by measuring everything to make sure you have the clearance in your home to have a new appliance delivered, measuring the space where your dishwasher will go to ensure a snug fit, and clearing out enough space in your home to house the new dishwasher while you prepare to install it.
Next, youll want to get all the tools you need to complete the job. Your dishwasher delivery will include smaller tools like screws, brackets, and clamps, but youll want to have some standard home improvement tools on hand, like a screwdriver, pliers, wrench, measuring tape, power drill, and flashlight.
Finally, you may want to consider calling in a buddy to help you through the process, either physically or emotionally. I was lucky to have a live-in spouse who did all the things I didnt want to . A delivery team will be able to move the appliances, but a buddy can help trade-off if youre struggling with a screw, or provide much-needed positive reinforcement throughout the journey.

Remove the dishwasher from the box and lay it on its back to look at the connection areas underneath. Your dishwasher will come with a drain hose that needs to be connected to the dishwashers drain line.
Remove the cap over the drain line connection and attach it to the drain hose. If a little water comes out of the drain hose, dont worry.
Its from the factory testing. 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.

Dishwasher Air Gapwhat It Does
Many local building codes require a dishwasher to connect to an air gap before the connection to a garbage disposer so wastewater doesnt flow back into the appliance. If your local codes require an air gap, youll need to buy it separately. Mount it on top of the sink. Connect one flexible hose to the drain of the dishwasher, and connect the other flexible hose to the trap of the sink or to the disposers dishwasher inlet. If your local codes do not require an air gap, you can shape the drain hose of the dishwasher into a high arc instead.
This video shows what an air gap looks like and where it goes, discusses whether or not you need one, and shows how to clear the air gap if it gets clogged.

Reconnect The Drain Hose

Remember when you threaded the new drain hose through the opening that leads to the cabinet under the sink? Now, youll attach it. 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.
Preparations For Dishwasher Installation
The first step is making sure the machine will fit in the opening. Most standard dishwashers require a 24 opening. If youre installing new cabinets, its important to consider the width of the dishwasher ahead of time. The height of most machines is adjustable within certain limits, but check to be sure the dishwasher you plan on purchasing will fit your opening before buying.
Depending on your cabinet configuration, you may need to drill one or more holes to run supply lines, electrical wiring, and the drainpipe through. Hole saws make quick work of drilling larger diameter holes.
Remove the faceplate at the base of the machine to access the supply line inlet and electrical box. Its a good idea to connect the wiring, drain, and supply lines before pushing the dishwasher into the cabinet, since it makes it easier to access the underside of the machine.

Setting Up The Cabinet And Utilities
Step : Temporary Hookup
Turn off the water supply to your faucet and drain any remaining water in the line by opening up the faucet. If you have an older home with galvanized pipes, this might be trickier. If thats the case, youll want to open up one of your sink drains and let some water drain out of there first.
Once the line is drained, remove the sprayer hose from your pull-out faucet by unscrewing the connecting nut. Unscrew the band clamp by turning counter-clockwise. If you have trouble doing this, try pushing inwards on the nut with a screwdriverthis will release some of the tension for you.
Slide your new dishwasher sprayer hose onto the faucet. Most dishwasher hose kits come with a connecting nut that should fit the existing threaded end of your pull-out sprayer hose, but if it doesnt you can replace it with one from your local hardware store. The new nut should be about half an inch longer than the original was. Make sure to use Teflon tape on all threaded connections to prevent leaks.
Now connect the other end to your portable dishwasher by securing the clamp band around the sprayer hose and tightening it with a screwdriver, just like you did above. Use Teflon tape here too. We also recommend replacing any plastic washers that might be included with your kit theyre only there to prevent leaks, so if theyre old or cracked, you might want to swap them out.
