M9/M11 Sterilizer Water Level Sensor Location / Function Test and Repair
During the Fill Mode
5 VDC is supplied to the water level sensor. When the water level in the chamber reaches the sensor disk, a circuit is completed, and current flows back to the PC board.
When the 5 VDC from the water level sensor is detected, the PC board stops the current flow to the fill valve.
