The purpose of a water level sensor in a dishwasher is to monitor and regulate the amount of water present inside the dishwasher during its operation. The sensor helps ensure that the dishwasher is filled with the appropriate amount of water for efficient and effective cleaning while preventing overflows or inadequate water levels.
The water level sensor typically works in conjunction with the dishwasher's control system. It uses various methods to detect the water level, such as pressure sensors, float switches, or conductivity sensors.
Here's how the water level sensor operates:
Monitoring water intake: When you start a dishwasher cycle, water is supplied to the dishwasher through an inlet valve. The water level sensor detects when the water reaches the desired level, signaling the control system to close the inlet valve.
Preventing overflows: The water level sensor continuously monitors the water level during the cycle. If the water level rises too high due to a malfunction or blockage, the sensor will detect the excessive water level and send a signal to the control system to stop the water supply and prevent an overflow.
Ensuring adequate water level: Conversely, if the water level drops below a certain threshold during the cycle, the water level sensor will detect this decrease and alert the control system. The control system may then initiate actions to ensure sufficient water is added, such as activating the water inlet valve again.
By accurately monitoring and controlling the water level, the sensor helps optimize the dishwasher's performance, water usage, and energy efficiency. It helps prevent potential damage caused by excessive water and ensures that dishes are effectively cleaned without compromising the safety and operation of the appliance.
