How to install a dishwasher


How to install a dishwasher

Fitting a dishwasher is not only a great way to save on the housework; it is also a great way to save on your fuel bills; and thus money. After you have purchased your first dishwasher you will need it installed properly, but if you would prefer to fit it yourself instead of hiring a professional, here are some tips to help you on your way.


Make sure that you have somewhere suitable to fit your machine. You will need somewhere that is relatively level, and that has access to water, drainage, and electricity. Buying a dishwasher and later finding you have nowhere practicable to fit it is avoidable, so think ahead. Make sure that you have thought about where your supply and drainage pipes will run too, or you could be causing a lot of heartache later.


Water Supply

Your water supply can be tapped off the water pipes you already have installed, but it is how you will tap the water, and how you will run it to your washer that matters. The usual choices are copper tubing or braided steel, and the choice will depend on ease of installation and the life of the pipe. A professional would tend to use copper tubing, as it will last much longer than the braided steel, and even the dishwasher. However, a braided pipe is much easier to fit, especially if you are unable to have a straight run of tubing.  Tapping into the existing piping is now a simple matter, and using a self-cutting connector is perfectly acceptable and something most people are able to do

Hot or Hot and Cold

Most dishwashers now come with their own heaters, and using these is usually more economical than using your homes supply. If your dishwasher has a heater, the chances are that you will be able to tap into the cold supply only. You should always check the manufacturer’s handbook to see if this is acceptable though.


Waste water will need to be removed from the system, and again you have a few choices. My suggestion would be to replace the water trap you have with one that has a spigot fitted. These are simple enough to fit (even for an amateur), and if you already have a washing machine fitted in such a way, you can always buy a trap with a double spigot. For those that cannot connect to a suitable water trap, you can buy a self-cutting spigot that connects straight onto a waste pipe. The only considerations being that it needs to go before a waste trap or you will be having a few bad smells around your home, and you need to make sure the hose is secured with a suitable hose clip.


Make sure that all connectors are fitted securely, but don’t over tighten or the plastic fittings can break. Also make sure that you don’t leave pipes or hoses hanging in free space, secure them to a wall or cupboard. Never stretch you pipes, so buying connectors and hose clips should be considered, especially as you will need to be able to pull any machine out of its recess without worrying about pipes and hoses breaking.

Level Your Machine

You should make sure that your machine is as level as possible, and this can usually be achieved with the adjustable feet on your machine. Leveling is another reason that planning where you will site your machine is so important; most of the leveling should have been done prior to installation, so only small adjustment should be needed afterwards.

If you have followed these steps carefully, you should now be able to sit down and relax while your first load is cleaned in your dishwasher.
