Water (level) Pressure Sensor
Water Pressure Sensor
The sensor operates on low voltage DC which can be read from the control board
connector J6.
The voltage will increase from ~ 0 vdc (empty) to ~ 2.1vdc (full) across terminals
1 & 2, (Beige to Purple) .
Terminals 2 & 3, (Purple to Black), will read the inverse voltage, the voltage will
increase on fill.
Test is performed at the control board with the harness attached.
Empty = 0 vdc
Small = 1.3 vdc
Medium = 1.55 vdc
Extra large = 1.85 vdc
Super = 2.10 vdc
Ps. If the water level is changed when testing, allow 30 to 60 seconds before the
motor stop and water valve is energised.
