Pressure Switch Failing Symptoms Top Loading Washing Machines
If the drain path is clear, the drain pump might have failed or the water-level pressure switch might not sense how much water is in the washer. In a top-load washer, a failed lid switch can keep the washer from advancing to the drain and spin cycle.
- Water Level Sensor (pressure transducer) As the water level rises, air pressure inside the Cabrio's pressure switch tube increases because of the water's weight. When the desired water level is reached, the pressure switch inside the Cabrio washer's control board cuts electricity to the water valves and turns on the recirculation pump.
- Learn about the reasons why your washer’s timer is not advancing. If the timer on your washing machine is stuck, it could be a broken knob, and if the timer is stalling on one of the cycles, like the rinse cycle a part like the start switch or the drain pump could be to blame.

(AGITATION) CYCLE
After the water valve closes, an electric motor starts which drives the transmission, sometimes through a belt, and in some cases through a clutch arrangement, too. The transmission converts the rotary motion of the motor to the back-and-forth motion of the agitator. A driveshaft extends from the top of the transmission to the agitator, where it is connected to the agitator, usually by a spline. (See Figure G-1.)
Agitation will continue for a certain amount of time, which is controlled by the timer. During agitation, some washers use their pump to circulate water, sucking it from the bottom of the tub and pumping it to the top of the tub. The pump is driven by the same electric motor.
Also during the agitation cycle, bleach or softener may be automatically added. This is usually done by a solenoid valve that allows some of the recirculated water to flush out the bleach or softener dispenser. In some models there is no water circulation involved; the solenoid simply opens a valve or door that lets the dispenser contents drop into the wash water. The timer tells this solenoid valve when to open.
