How to connect a dishwasher

connect dishwasher

A dishwasher is in the household a great relief. But before use comes the question of how to properly connect the dishwasher. It certainly works with this guide to install a dishwasher. With the right instructions, it is not difficult to connect a dishwasher yourself.

Whether large family or single household – dishwashers come in many different designs and sizes. Often you will be replaced or reinstalled during kitchen renovation. Many questions then, how to connect the practical kitchen helper now. We explain how to do it – step by step.

For the dishwasher connection you only need a pipe wrench and a bucket or a bowl for leaking water. It also does not hurt to have a rag handy.
1. Close the water connection

In order to avoid flooding in the apartment, you should necessarily turn off the main water tap before installing the dishwasher. In single-family homes, this is usually found in the basement, in apartments usually in the bathroom. To be sure, you should also turn off the connection below the sink in addition to the main water supply. Mostly it consists of a hot and a cold water pipe.
2. Connect the supply hose

Commercial dishwashers have a white inlet hose and a gray drain hose. To install the water supply, you need a corresponding connection under the sink, which in most cases should already be present. Now open the free valve with the pipe wrench and connect the supply hose of the dishwasher with it. Use the pliers to tighten the lock.

If there is no free water connection, you must first remove the existing valve and replace it with a double valve. You can get this Y-distributor at the hardware store. To protect your kitchen from flooding in case of emergency, you can optionally install a water stop valve between the supply line and the water connection.

Tip: Even if you have turned off the water beforehand, water can escape when you open the valve. Therefore place a bucket under the opening and hold a rag ready.
3. Fit the sewage hose

Just as important as the supply hose, which supplies the dishwasher with water, is the waste water hose, which removes the dirty rinse water again. Attach the connection to the siphon and secure it with a metal clamp.

Important: Make sure that both inlet and outlet hose do not kink.
4. Connect power

After you have connected the water hoses and aligned the dishwasher, you still need to set up the power supply. There is usually a power outlet nearby for this purpose. There connect the dishwasher to the mains. Do not use extension cords or multiple plugs as this can quickly lead to a short circuit in the event of an emergency.
5. Check the dishwasher for leaks

When all hoses and the power cord are connected, first check that all connections are tight. To do this, proceed in the reverse order: First, turn on the main water tap, then the valves under the sink. Now, if you turn up the water there, you quickly find out whether water is leaking at the valves. If this happens, grab the pipe wrench again and tighten the valves. After a test run, the dishwasher is ready for use!
