Installing a Dishwasher in 6 Easy Steps

It is hard to know where to start when completing a dishwasher installation. Simple tasks such as finding the water supply or drain hose can become complex tasks to an untrained eye. But we can easily break down what sounds complicated and make it an easy and almost pleasant experience for you. Before you know it you will be a dishwasher installation king or queen. Here are our six easy steps on how to install a dishwasher.

1 – Turn off your water supply

Before you install anything, you need to make sure that you completely cut off all water by finding the shutoff valve which closes off the water supply line. If you don’t manage to cut off the water supply first then you might find when you either disconnect the old dishwasher or you mess with any pipes, you may find yourself head to toe in hot water.

So remember, the water supply line should remain off from the very start, right up until the very end. Do not be tempted to skip this part.

2 – Run full checks on your new dishwasher

Whenever you go to install a dishwasher, you should always complete checks on your new machine. You can do this by giving your dishwasher manual a read. Check if there is anything unique to the dishwasher that isn’t mentioned on this site. Every dishwasher is different with a unique access panel and you need to make sure that you don’t miss a trick on your new dishwasher.

By checking your manual before the installation, you are saving yourself from any nasty little surprises further along the way. A new machine rarely works perfectly the first time and you want to make yourself familiar with the many potential error messages that may appear.

You also want to ensure that nothing on your machine is broken. If you notice something broken or not looking particularly like it should then make a note of this right away and perhaps even contact the company you purchased it from.

3 – Connect the water supply

Now once the hot water is turned off at the shutoff valve and you are familiar with how the dishwasher is shaped and where things are located, it is time to connect to the water supply. No dishwasher is going to work without running water which is why the first most important thing to do is connect the dishwasher to your home’s water supply hose.

It is vital that once you have connected your pipe, you screw it in tightly to stop any leakages. You will not want a leak behind the dishwasher once you have moved everything into place. This is a fairly simple task and all the complex stuff is taken care of, an air gap is installed inside the machine to prevent any water from becoming contaminated.

4 – Connect the drainage

We have installed a way for the water to come into the dishwasher, so the next thing we need to do is install an exit route for the water and your food waste. This is what we call the drain hose and it acts just like a sink drain. This is done by connecting your built-in pipe to the standpipe, the hose will sit loosely in the pipe which again you want to try and tighten if possible.

An air gap will be installed into your dishwasher to stop any of your contaminated water from reentering the machine. If you cannot find your air gap then take a look at your manual to see where it is.

Check this over and over to ensure that it is always connected properly before putting the machine back in its position. All it takes is for a loose pipe to come out from its rightful place and soon fill your kitchen floor with last night’s dinner. Remember to check once, and then check again.

5 – Check your dishwasher is level

Your dishwasher is almost ready to go, but firstly another important task is to check that your dishwasher is level. If the dishwasher is not level then you may find that water will struggle to make its way to the drain hose. If the water fails to make it to the drain hose then the dishwasher will not drain and it will therefore not work to its maximum ability.

You can easily make your dishwasher level by using a spirit level. You can position it on top and the bubble will soon tell you if you are going to have issues. Once the bubble remains in the middle of the spirit level you have a perfectly straight dishwasher. Remember to position the spirit level in many directions as there are various ways in which the dishwasher can become unlevel.

6 – Time to turn it on

That is all the hard work out of the way (well, except for putting the old dishwasher into the garbage disposal). Now you just need to connect your dishwasher to a power supply. Plug it in and watch the magic begin.

Whilst you play with your new dishwasher you may notice an error or two. If you do find that you have an error then make sure you return to your dishwasher manual where there may be further steps on how to install a dishwasher.

A dishwasher can take up lots of energy to ensure you are taking the right precautions to save money where you can. There are many handy guides on the internet that can help you do this, such as this one.

Considerations

Safety

When learning how to install a dishwasher, the most important thing to learn is how you can be safe. There are a few things to remember to ensure that when you install the new one, you do not cause yourself any damage.

First things first, make sure all of your pipes and power supplies are turned off. A dishwasher is a lethal combination of water and electricity so you do not want them to be mixing. So turn off the pipes at the water supply valve and flick your power switch off. Only turn both of these on when you are ready to go.

Measurements

At the start of any project, you must complete accurate measurements. You do not want a worst-case scenario of your dishwasher not being able to fit and you have to leave it at the garbage disposal.

When looking at dishwashers you should always measure your kitchen before you buy a new one. Dishwashers come in all shapes and sizes and not all of them will fit in your kitchen.

Tools

Finally, before you get started you need to ensure you are prepared. You can read all the manuals and watch all the videos on youtube. But if you do not have the right tools there will be no new dishwasher and you will be stuck with the old one for much longer.

We would recommend a bucket, adjustable wrench, and a spirit level to keep you on the right track. You may also want to bring a towel along with you to tidy up any spillage that may leak out of the pipes or sink drain.

FAQs

Can I install a dishwasher myself?

There are absolutely no reasons why you cannot install a dishwasher yourself. Whether you use this handy guide or watch a youtube video, the process is simple enough. Just remember that water needs to go in, water needs to go out and there needs to be the power to move everything around.

All the complex stuff is already built into the machine, such as the air gap which prevents any contaminated water from entering back into the dishwasher. Therefore, it is as simple as connecting a few things and you are usually ready to go.

If you have any issues that this article or a youtube video cannot explain, then always resort back to your manual which should have a troubleshooting page to help get to the bottom of the issue.

Do I need an electrician to install a dishwasher?

Most of the time it is very unlikely that you will need an electrician to fit in your dishwasher. One instance where you may need an electrician is if you do not have a plug socket available to the proposed location. Most modern dishwashers can plug into your mains and do not need to be wired in.

If you do not have a mains plug near your chosen location, then you may need to consider the idea of getting in an electrician to do the job. We would never recommend taking on the electrics yourself and you should always let a professional do the job.

Alternatively, if your dishwasher is causing regular errors on the screen reader and your research is not bringing any results. Then you may want to request an engineer to come to look at the machine to see if that can be fixed.

How often do you need to replace a dishwasher?

Dishwashers have a long shelf life and you can expect a modern machine to last up to ten years, which will include a lot of clean pots in the process. After about ten years you may find that the machine does not clean as well as it used to and you may want an upgrade.

Replacing a machine is not always cheap though so you want to ensure that you are always buying efficient devices that will give you many miles. When looking to purchase a new dishwasher you should always look into ways of saving money on appliances. The general thing to always remember is that you want a dishwasher that can last as long as you possibly can.

Another thing to remember is not only should you replace your machine once it stops cleaning your pots and pans. But also, you may want to start replacing your machine now and again to keep up with the latest technology. There is always a new device to come out that will blow the competition away with brand new ways to efficiently clean your pots and save you money in the long run.

Many modern machines ensure you are using less electricity to clean your pots and therefore saving money on your bills every month. Sometimes a new machine is worth the investment.
