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.
