How to Open OR Turn on the water valve on a Washing Machine?

Water valve position and types depend on the make of your washing machine and its model.

Water Valves are attached to the main supplies and connect the washer through inlet hoses. These hoses are attached to the washer’s water inlet valves.

When you turn on the water valves it releases the water towards the inlet valves through the water inlet hoses.

These water inlet valves have a self-locking mechanism that works with the water level sensors.

The inlet valves release the water inside the washtub only after a signal is triggered through the sensors during a wash cycle.

This is a complete guide to opening or turning on the water vales.

How to turn ON the water valve on a washing machine?

Turning on a water valve is referred to as allowing the water supply towards the washer.

It releases the water flow towards the washer during a wash cycle and you can shut off the water supply to your washer by turning them off.

Depending on the wash type (using hot or cold water), these are usually connected to the main supplies of the washer.

With the help of a water pump, the water is released towards the washer, and there are water valves that look like outdoor faucets or valves, one for hot and the other for cold water.

These water valves can be manually turned Off and On.

A few Washers are designed to function using only cold water or normal supplied water while most washers have dual supplies with cold as well as hot water.

Steps to turn on the water valve in various washer supply types

Coldwater Washer

Washers that only supply cold water will have a single water inlet hose connected to the Washer’s inlet valve at one end and the other end is connected to the water supply valves or the faucets. 

Simply turn on the taps with a rotation in the right direction and it will allow the water to flow towards your washer.

Similarly, turn them off with a reverse rotation towards the left.

Hot & Cold Washer

Washers using hot and cold wash types will have dual hoses installed at the back, one for the cold water and another for the hot water supply.

The other ends of the inlet hoses are connected to the water pump valves.

The water pumps are installed close to the washer and are responsible for releasing the required water types (hot and cold).

Depending on the fixtures, the water pump valves are usually available in red and blue colored knobs, handles, or buttons.

Red indicates that it supplies hot water whereas blue indicates cold water supply.

Let us see how these work.

Knobs: Knobs can be rolled towards the right to turn ON the water supply and to the left in order to shut the water supply. (Red knob for hot water and blue for normal)

Handles: Simply turn the handles to the extreme right in order to allow the water supply towards your washer. (Red handle for hot water and blue for cold or normal water)

Buttons: Simply press the Red button for hot water supply for cold press the blue button. Press them again to turn off the water supply and the light will turn off.
