Washer Sensors and Functionality. Washer Sensor Shut Off

Today’s modern washing machine typically operates on the ‘sensor’ technology of air pressure, based off of the water level control (WLC) mechanism found inside of your washer.

There are typically 3 air-flow and contact terminals in which work conjointly to relay necessary opening/closing of the valves and trigger water-disbursement as necessary—or to the desired “fill”.

When a washing machine is at rest, the open air valve leading to the open air dome on the outside of your washer should be closed—as it’s not necessary to disburse air since none is being collected. However, when the washing machine is being used, this terminal and hosing is open to release the air pressure built up inside of the washer, once it’s communicated a ‘full’ status to its internal computer.

Thanks to the water pressure that accumulates when you first turn your washer on to cycle, this air pressure is then relieved into an air hose and goes through a sensor before leaving the washer that tells the washer when to release or change cycles, as well as when to stop filling—as to prevent overflow.
Internal and electrical sensors known as diaphragms are the physical modules both inside—and sometimes outside—of your washer that communicate with one another to cycle through the modes, sense air pressure, water pressure, and even depth.

Given these three terminals and the air tubes involved in a typical washing cycle, it becomes more evident that air pressure is essential when responding to an internal sensor or physical pressure gauge that relays when your washer has reached the desired fill capacity—based on the settings you choose within the settings knob prior to operation.
