INFORMATION
The water pressure sensor connector MUST be plugged into the appropriate PCB.
4 Measure the voltage on connector X60A between pins 2–3 (= water pressure
sensor output) on the hydro PCB.
5 Check that the measured voltage is in line with the expected voltage through
the measured water pressure.
INFORMATION
In most cases, the user interface allows to monitor the water pressure.
If the measured output voltage value matches the voltage determined through the
measured water pressure, but the water pressure is NOT correct on the user
interface display, replace the applicable PCB.
The measured voltage is inside the
expected range?
Action
Yes Water pressure sensor is OK. Return to
the troubleshooting of the specific error
and continue with the next procedure.
No Continue with the next step.
