Inside the washing machine, there is a pressure hose connected to the base of the tub and the pressure switch. As the tub fills with water, air is trapped inside the pressure hose. The pressure switch senses the increase in air pressure and uses it to determine when to stop filling the tub.
Step 1: Water Filling
When you start a wash cycle, the water begins to fill the machine. As the tub fills, the air inside the pressure hose is compressed due to the increasing water level. This causes the air pressure to rise inside the hose, which is detected by the pressure switch.
Step 2: Pressure Detection
The pressure switch, also known as a water level switch, is responsible for monitoring the air pressure inside the hose. It is usually located near the top of the machine, close to the control panel. The pressure switch has electrical contacts that get activated or deactivated based on the air pressure inside the hose.
Once the pressure inside the hose reaches a specific level, the contacts in the pressure switch are triggered. This sends a signal to the control board or timer, instructing it to stop the water from filling the tub.
Step 3: Water Drainage
Once the desired water level is reached, the washing machine moves on to the next phase of the cycle. At this point, the water starts to drain from the tub. As the water level decreases, the air pressure inside the pressure hose also decreases.
When the air pressure drops below a certain threshold, the contacts in the pressure switch are again triggered. These contacts then send a signal to the control board or timer to stop the draining process and move on to the next cycle, such as agitation or spinning.
In summary, the pressure switch in a washing machine is responsible for accurately monitoring the water level inside the tub. By detecting changes in air pressure, it ensures that the correct amount of water is used for each cycle.
