High Water Sensor Sensing Low Water
The photo to the left shows the high
water sensor (Violet) wire. As the caption
shows the meter is reading a voltage of
4.09 V
DC.
Water in the housing is not
touching the high water probe. When this
occurs, the control board would activate
the cold inlet valve for the steam
generator before energizing the heater, IF
steam was selected and the control board
wanted steam.
High Water Sensor Sensing Full
In this picture we see the meter displaying
less than 1.5 V
DC.
In this example, the
water in the housing is touching the high
water sensor probe and the ground
probe. When this occurs, conductivity
through the water is measured as a
voltage drop and the control board knows
the water housing is full of water.
