How to connect a dishwasher to hot water

Middle-aged and elderly people cannot get used to bills for housing and utility services. Some people are so obsessed with this issue that they are constantly looking for something else they can do to save $1. According to users distributing advice on social networks, connecting the dishwasher to hot and cold or only hot water will provide significant savings. Is this really true, is it possible to connect the machine to the hot water supply yourself and is it worth doing, let’s find out.

Connection features

Connecting a dishwasher to hot water is not the same as connecting to cold water. It is very important to remember a number of features that must be taken into account when making such a connection.

You should take an inlet hose designed for hot water.
Read the instructions for your dishwasher first. You need to understand whether the manufacturer allows or does not allow the connection of its product to hot water supply.
Between the inlet hose and the outlet of the hot water pipe, install an additional flow filter that will trap impurities contained in the hot water.

Remember! Although the service provider claims that the hot water supplied to the pipes is absolutely clean, our experience tells us the opposite. So it’s better to play it safe and install a filter, and then check it at least once a year.

terminals for connecting a mixer, dishwasher, washing machine Before connecting the dishwasher to hot water, you need to assemble all the components. First, we take a high-quality inlet hose that can withstand hot water.By the way, such a hose can be included with a dishwasher, especially if such a machine is designed to be connected to a hot water supply. Secondly, a tee tap, with the help of which you can organize the connection and then turn off the water when the need arises. Thirdly, let’s take any flow filter that fits the inlet hose and we can get to work.

For such work, no special tools are required, the hose is quite easily screwed on by hand, and in order to securely install the tee tap on the outlet of the water pipe, you need to take fum tape and a small adjustable wrench. So let's get started.

We turn off the hot water so that we are not splashed with boiling water.
Remove the plug from the outlet of the water pipe.
At the end of the pipe outlet, screw a fuse directly onto the thread.

We screw the foam in a small amount against the thread.

We screw our faucet for connecting a dishwasher and make sure the connection is tight.
We screw a plug onto one terminal of the tee, and screw a fuse onto the other.
We screw the end of the inlet hose onto the free outlet of the tee, making sure that its other end reaches the dishwasher body normally.
We screw the flow filter to the second end of the hose, and then screw this entire structure to the filling valve of the machine.

Finally, we need to open the water and check how tight the connections are. If everything is in order, you can test run the dishwasher connected to hot water. Strictly speaking, a dishwasher needs cold rather than hot water, so the equipment will last longer, but if you really want to connect your “home assistant” to the hot water supply, you can do this. Just keep in mind that there are both pros and cons to such a connection.

Advantages and disadvantages of such a connection

If you connect the dishwasher in the traditional way and use only cold water, then the machine operates in normal mode. But if we connect the dishwasher to hot water, some unforeseen situations may arise. Let's start with the advantages of connecting the machine to hot water.

The washing process is faster because there is no need to heat the water in the tank.
The heating element wears out more slowly because it has to be turned on less often. This thesis is controversial, but we will still take it into account.
Energy saving. In this case, we save on electricity, but at the same time we waste expensive hot water, so the money will not be cheaper, but rather more expensive.

As you can see, the advantages are very, very dubious. There is no need to make an effort to turn the information provided and turn advantages into disadvantages, although the final decision is of course yours. Now about the absolute disadvantages of connecting the machine to a hot water supply.

Hot water damages the meshes of flow filters, so they have to be changed frequently. At the same time, you can’t do it without filters either, otherwise all sorts of debris and dirt will end up in the dishwasher.
Very hot water damages the pipes and drain hose of the machine, which reduces the life of the dishwasher.
Under normal conditions, during pre-washing in a dishwasher, dishes are rinsed with cold water, which only begins to warm up during the main wash. Imagine if the preliminary rinsing takes place in hot water.This will end with the fact that the remains of buckwheat, dough and other food that does not tolerate hot water will stick to the dishes and the quality of washing will decrease.

It will be impossible to wash anything in cold water, since the dishwasher can heat the water, but cannot cool it.

After reading the above information, many begin to doubt whether it is really necessary to connect their favorite “home assistant” to hot water. If you are still used to standing your ground to the end and it is not easy to convince you, read the next paragraph, which you may find interesting.

About hybrid connection

connection to both hot and cold water Some expensive dishwashers have what is called a hybrid water connection. They can be connected in three ways: only to cold water, only to hot water, to cold and simultaneously to hot water. Our experts like the last option the most and here's why.

A user whose dishwasher is connected to both cold and hot water can really save money by choosing the most preferred washing mode. The machine itself will mix hot and cold water in optimal proportions, instantly supplying a mixture of water and detergent to the dishes. There is only one drawback here - the abundance of hoses that need to be carefully hidden behind the body. But if you succeed, you can enjoy using a hybrid machine for many years without having to deal with dirty dishes!

To summarize, it should be noted that dishwashers can be connected to hot water supply only if the manufacturer allows this. If you connect a machine that is not designed for hot water, you will ruin the equipment. Good luck!
