How does an automatic washing machine choose water level?
So, in simple terms, the water level in the washing machine is decided as per the size of the load, the type of fabrics, and the cycle you want to run. This is done with the help of a few built-in sensors. The load-sensing device senses the load and signals the pressure switch to fill the right amount of water into the machine.
