A dishwasher is one of those appliances that more and more people cannot imagine a functional kitchen without. If you are a lucky owner of a new dishwasher, you will need to connect it to the sewage system.
If you do not know how to connect the dishwasher to the sink, you have come to the right place - our guide will take you step by step through this process. We will advise you on how to connect the dishwasher drain to the syphon, explain how to check if you succeeded, and also help you choose the best syphon for your kitchen.
What do you need to connect a dishwasher?
Here is a short list of what is needed to connect a dishwasher to the water and sewage system:
- pipe wrench – will allow you to tighten and loosen various installation components,
- screwdriver – useful for installing and removing various elements,
- wire cutters – will allow you to trim the drain hose to the required length if necessary,
- teflon tape or sealing paste – useful for properly securing threaded connections,
- level – thanks to this, you will check if the dishwasher is set evenly - this is important for the proper functioning of the device.
This few accessories should be enough to carry out a quick connection of the dishwasher to the water and sewage system by yourself.
Connecting the dishwasher step by step
Connecting the dishwasher to the sewage installation is a task that can be done independently. If you do not have a separate outlet for sewage to which you can connect the dishwasher hose, there is no need to rebuild the installation. You can connect the dishwasher using the appropriate sink syphon.
Below you will find a detailed description step by step of how to properly connect the dishwasher to the water installation.
How to connect the syphon to the dishwasher?
The first step is to choose the right place in the kitchen. The dishwasher should be placed in close proximity to the power socket and the water source and drain.
Connecting the dishwasher to the sink syphon will allow you to properly drain the water from the device after the washing process is complete. If you already have the appropriate syphon, make sure you also have all the necessary tools and materials at hand, including the syphon wrench, flexible hose for the dishwasher, rubber seals (if they are not supplied with the syphon), and sealing tape. Then:
- turn off the water supply,
- disconnect the drain hose from the sink drain pipe,
- connect the dishwasher drain hose to the inlet pipe of the syphon,
- make sure the hose is well secured with a clamp,
- connect the sink drain hose to the outlet pipe of the syphon,
- turn on the water supply.
If the dishwasher is already connected to the syphon, ensure that the syphon is properly secured and sealed. It is best to buy a special syphon designed for connecting a dishwasher. If you do not have such a syphon, it may be necessary to use a special adapter or connector.
Remember!
The water drainage should occur at a height of not less than 30 cm from the floor. The diameter of the sewage pipe must be at least 40 mm, which will allow effective drainage of water.
Connecting the dishwasher to the water
The next thing to do is connect the dishwasher to the water supply. This is essential for the device to operate properly. This process is even easier and does not require special skills.
- The first step is to turn off the water supply valve,
- then connect the flexible hose supplying water to the water installation – to the pipe supplying cold water,
- the other end of the hose should be secured to the water inlet valve of the dishwasher - you will probably find it on the back wall of the device,
- turn on the water supply valve.
The hose connections must be tightened securely with a wrench to prevent water leakage. To check if everything is in order, turn on the water supply and carefully verify that nothing is leaking anywhere.
The flow of water should be free - make sure that the water supply hose and drain hose are not bent or pressed against the wall or floor.
Connecting the power supply to the dishwasher
The last thing you need to do before starting the dishwasher is to connect the device to the power socket. To ensure maximum safety, make sure the socket is equipped with a grounding pin. Lack of adequate grounding can cause electric shock.
The power socket should be located no closer than 60 cm from the water outlet, which will minimize the risk of flooding the socket.
How to verify that the dishwasher connection process was successful?
After successfully connecting the syphon to the dishwasher, conduct a test to ensure that everything is working correctly.
- Start the dishwasher,
- observe whether the water drains freely and if there are no leaks,
- also check that the supply and drain hoses are not tense or bent, which could cause water flow problems.
If any problems occur, such as incorrect water flow or leaks, check that all connections are tightened and properly secured. It is also worth checking that the water pressure is not too high, as this could cause connection problems.
In most cases, the dishwasher will automatically respond to a lack of water and simply stop, but if there is a problem with the drain, it can unfortunately be easily overlooked. Secure the drain hose carefully and seal it both where it connects to the syphon and to the valve in the dishwasher.
Which syphon is best for a dishwasher?
Choosing a syphon for a dishwasher is a very important process, as it affects both the way of connection and the later use of the appliance. It mainly depends on the kitchen configuration and the type of dishwasher you have.
The plumbing market offers a wide selection of various sink syphons. The most commonly chosen are:
- bottle syphons – have a closed design, are easy to install and clean,
- pipe syphons – work well where a larger diameter drain is needed - they are ideal for kitchens.
Additionally, there are models with side drains and models equipped with special branches that allow for the connection of a dishwasher.
There are also syphons with more than one branch, allowing for the connection of two devices to one drain. This is a convenient solution if you want to install not only a dishwasher but also an additional washing machine in the kitchen.
Connecting the dishwasher to water and sewage – summary
As you can see, connecting the syphon to a dishwasher is not a difficult task and you can successfully do it yourself. The entire process should not take too much time. If you already have a sink syphon installed in the kitchen and it is not suitable for the dishwasher, you should buy the appropriate model equipped with a special branch.
We have discussed how to connect a dishwasher to a syphon. It is worth replacing the syphon with one that will fit the dishwasher. This process is also relatively easy, and the tools and accessories mentioned in the article will be sufficient to carry it out. Additionally, it is worth equipping yourself with a bucket or other type of container to catch the water from the disassembled syphon.
How to connect the syphon to the dishwasher? Here is a quick rundown of this process:
- turn off the water supply valve,
- disassemble the existing syphon,
- connect the new syphon so that the additional inlet is directed upwards and is on the side of the dishwasher,
- turn on the water and run the faucet,
- check for any water leaks at the connections.
Once you have secured the appropriate syphon, you only need to connect the dishwasher's drain hose to it. Make sure that the dishwasher hose is directed upwards - it should be shaped like a U, as this will prevent unpleasant odors from the drain from entering the dishwasher.
