Hi there I am Joel and I will be helping you today,
The component that controls the water level of the washer is called the water level pressure switch, the way it works is there is a rubber hose that connects to the switch and runs to the tub, as water fills the tub it pushes air through the hose and puts pressure on the switch the more water that enters the tub the higher the pressure becomes until the switch is satisfied, this is how the machine knows when to shut off the water. Now if that switch fails or the hose is pinched or stopped up with trash it will allow too much water into the machine or even allow it to overflow. The switch is located on the top of the unit mounted on the right side under the lid, just remove the lid and you will see it - see image
check the hose out for tears or being clogged up if the hose checks out ok then replace the switch:
