ERR 9 "Water metering problem!"
Pump limit stop time-out in filling; limit
stop not reached after15 s
■
Check the pump operation from the
maintenance screen:
- place the nozzle on the tank,
- enter a sufficient value for the amount of
water and press ON
- check that the switch is activated ("ON")
each time the piston is at the back.
■
If the piston does not move, or stops
moving too early, there is a mechanical
failure or a motor failure: check motor wiring
and connections, then replace the pump if
the problem is not solved.
■
If the piston moves normally while the
switch is never activated ("OFF"), there is a
switch failure: check switch wiring and
connections, then replace the pump if the
problem is not solved.
■
If the problem is not solved, replace the
CPU board.
