Never turn on the seal wash pump, while the pressure sensor is connected to the
main board port.
Make sure the seal wash cable and the pressure sensor cable are plugged in the
correct positions before turning ON the seal wash pump.
Pressure sensor and seal wash pump
connector were connected to the wrong
position on the main board (identical
connectors allow to plug into the wrong
positions by mistake).
Flow too low.
Pump OFF.
Suggested actions
Switch the connectors of the seal wash pump
cable and the pressure sensor to meet the
correct positions (P23 for seal wash cable, P29
for the pressure sensor cable from the multi
assembly).
Suggested actions
Recalculate flow or wait time, to allow to reach
encoder position before encoder position
time-out.
Turn ON pump.
