The Whirlpool WP22002921 Washer Water Level Pressure Switch measures the internal tub pressure by the use of an air hose that indicates when specific fill levels are reached. It works by reacting to pressure fluctuations that actuate an internal process to provide an electrical response to control the water intake. It is mounted close to the upper control zone and attached to the panel and wiring and the pressure tube. Its positioning allows proper sensing, regulation and constant cycle control.
