Pressure Sensor - GE PTAN9150MWW Technical Service Manual

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.
