How to connect a washing machine and dishwasher

The dishwasher and washing machine can be connected simultaneously in the same room, and without particularly changing the communications. This is required in cases where it is not possible to place the washing machine in the bathroom, so it is moved to the kitchen and placed next to the dishwasher. In this publication we will talk about how such a connection is made and what features there are.

What will you need?

In order to simultaneously connect two devices that are so dependent on communications, it is necessary to prepare these communications. It would be very simple if the kitchen already had separate water supply and sewer outlets specifically for the dishwasher and washing machine, but since they don’t exist, you’ll have to come up with something.

First of all, we will collect the necessary materials that will help us “integrate” into existing communications. Let's list them:

• triple tap made of bronze with a 3/4 section. Don’t take a plastic tee; if you don’t have a bronze one, take a silumin one. From such a tap we will make a high-quality double water pipe outlet.
• Bronze straight-through tap with two outlets (2 pcs.)
• FUMka.
• Siphon with two fittings for connecting two drain hoses.
• Adapters for drain hoses.
• Longer drain hoses or an additional set of hoses to extend the stock hoses.
• Flow filters with a 3/4 section.
• Voltage stabilizer designed for at least 3.5 kW.

A voltage stabilizer will help us avoid radical alterations in electrical communications; at the same time, it will provide good protection for expensive household appliances from failures in the electrical network.

We will also need tools; without them we won’t be able to connect the washing machine and dishwasher, but their list will be much more modest. You literally only need a small adjustable wrench, pliers, a spirit level, and a screwdriver.

Preparation for installation of two devices

Let's imagine this situation. A dishwasher is already installed in the kitchen, but there was a need to connect a washing machine at the same time. First, you need to at least find a place for it, because a washing machine is far from a small household appliance.

In such a matter, it’s difficult for us to give any advice; after all, this is your kitchen. It is possible that installing and connecting the washing machine will require some kind of compromise, for example, you will have to give up some pieces of furniture or make a rearrangement. One way or another, try to place the washing machine and dishwasher closer to the sink, because it is under it that the connection to the water supply and sewerage will be located. You also need to strengthen and level the floor where the washing machine is installed; to do this, use a building level.

Do not forget that there must be a gap of at least 1.5 cm between the washing machine and surrounding objects, since the machine vibrates strongly and sways from side to side during the spin cycle.

You can install a washing machine and dishwasher to the right and left of the sink, in which case it will be much easier to organize the drainage from the water supply and sewerage.You can place the dishwasher directly next to the sink, and place the washing machine next to the dishwasher, leaving a 1.5 cm gap between the walls of the appliances. There may be many options, but you will still choose the one that is most suitable in your case, so we will not impose your opinion.

Connect to the water supply

There are two ways to organize a water supply drain to simultaneously connect both a washing machine and a dishwasher. The first method involves connecting to the outlet of the cold water pipe at the sink, and the second to a special outlet of the cold water pipe.y. Both methods are common, so let’s look at them in more detail.

If the renovation of the kitchen was carried out a long time ago, and no one imagined that someday a washing machine or dishwasher would be installed in this room, then there are no free water pipe outlets. But it doesn't matter. We will make a branch from the cold water pipe that goes to the sink. Let's perform the following manipulations.

1. A hose extends from the metal-plastic pipe with cold water, which in turn is connected to the mixer. We need to first shut off the water and disconnect the hose from the pipe.
2. Between the hose and the pipe we will install a bronze tap with four outlets through an adapter. Two outputs will be used to connect the pipe and hose going to the mixer, and the other two outputs will be used to connect the washing machine and dishwasher to the water supply.
3. Next, we will install two flow-through taps at the two outlets of the tap and insulate the connection well.

We install flow taps in order to shut off the outlets to the washing machine and dishwasher separately, but if necessary, it will be possible to turn off the water in both the washing machine and the dishwasher at the same time.

4. We screw the inlet hose of the washing machine to the thread of one flow tap, and to the thread another dishwasher hose. This is where the water supply drain is organized.

The second option for connecting to the water supply is very similar to the first, only in this case we will use a tee tap. We screw a tap-tee onto the finished pipe outlet with cold water through an adapter. Thus, instead of one tap, we get two. Next, we screw the pass-through taps onto the outlets in exactly the same way and connect the inlet hoses of the washing machine and dishwasher.

Connection to sewerage and electrical network

Now we need to solve the problem associated with connecting two household appliances to the sewer. Extending the drain hoses is not so bad. You can buy adapters, additional hoses of a suitable cross-section and the job is done, but how to connect these long hoses to the drain? This question has long been answered by manufacturers of plumbing fixtures, in particular siphons for sinks. There are siphons on sale with two outlets for drain hoses, in other words siphons with two fittings.

So, we simply buy a new siphon with two outlets for the kitchen sink, install it in place of the old siphon and connect two drain hoses from the washing machine and dishwasher to it, respectively. The connection points between the siphon and hoses must be secured with clamps.

Do not forget to comply with the requirements for the height of the connection of drain hoses so that a siphon effect does not occur and water from the sewer does not flow back into the washing machine and dishwasher.

Connecting to the electrical network is more difficult to organize, especially if the kitchen has only one suitable outlet with a moisture-resistant housing, the wiring of which is designed for only one large consumer. Connecting two large consumers directly to such an outlet is dangerous, but you can use a trick - connect via voltage stabilizer for washing machine. You can read more about these devices in the corresponding publication posted on our website.

Checking the work

We connected both the washing machine and the dishwasher at the same time. Since organizing the connection turned out to be more difficult than in a normal situation, everything needs to be checked carefully. We load the laundry into the washing machine (you can run it idle in a special mode), put the dirty dishes in the dishwasher and start these two appliances at the same time. While the washing and washing programs are being executed, our task is to carefully monitor the communications. Particular attention to the connections between taps and hoses.

If a leak is suddenly discovered, it is urgent to turn off the water and stop the operation of both appliances, so as not to flood the entire floor in the kitchen and flood the neighbors. Then you need to unwind the problematic connection, reel it in more carefully, and then twist it again.

To summarize, we note that in order to organize the connection of both a washing machine and a dishwasher at once, you do not need to call specialists and pay them a lot of money.It is enough to read this article carefully and, using the help of a friend or relative, make such a connection yourself. We think that you will not have any particular difficulties. Good luck!
