Jura Impressa A1-A7-A9-ENA Micro Water Level Sensor - MS-324/244F
The water level sensor is located inside the coffee machine behind the panel where the water tank rests. When the water tank is filled with water, the magnetic float in the water tank rises, making contact with the internal water level sensor. The sensor sends the message to the PCB that the water tank is filled. This allows the coffee machine to proceed to the next function.
