Fill Funnel And Hose - Haier GE GDF450P R0 Series Technical Service Manual

Testing the Pressure Sensor: To verify the
pressure sensor is receiving power, remove the
connector from the sensor and test for 5 VDC
between pin 2 (+) and pin 3 (-) on the sensor. To
verify the sensor is properly sending the water
level signal to the machine control, test for
frequency (0 to 5 VDC) between pin 7 (+) and
pin 6 (-) on the machine control connector J603.
Use the chart under No Fill Diagnostics later in
this section to determine if the output frequency
corresponds to the water level observed inside
the dishwasher.
NOTE: When flood trip point is reached (40.11 to
39.69 Hz), the drain pump will turn on.
