The Whirlpool W10510877 is a water level pressure switch built exclusively for Whirlpool washers. This is vital to ensuring that your garments receive the appropriate amount of water during each wash cycle. This switch monitors the water pressure inside the washing machine tub. As water fills the tub, the increased pressure generates a signal that is delivered to the control board. When the desired water level is attained, the switch causes the control board to close the water intake valve. This guarantees that your clothing is thoroughly cleaned without using too much water, which can contribute to longer wash durations and higher utility bills. A broken water level switch can cause a variety of concerns, including the washer overflowing with water or failing to fill.
