9. PROBLEM SOLVING

9.1 WHAT TO DO WHEN THE VACUUM CLEANER EXPERIENCES A LOSS
OF SUCTION
When the appliance has been used for some time and you notice that the suction power is weaker than
before or that there is no suction at all, take the following steps:
a) First check the dust container and empty it. After emptying the container, if suction remains weak,
clean the filter as well. The machine should work satisfactorily after carrying out these steps.
b) If some inlet valves work whilst others don't, this could be explained by blockages in the ducting.
c) If there is no suction at any of the inlet valves unplug the air inlet connection from the central vacuum
unit.
If there is suction from the central vacuum unit, it means that there is an air leak or an obstruction close
to the central vacuum unit. Check all the inlets to find the point of the leak. If you cannot locate this,
contact your service engineer.
d) If the central vacuum unit still provides no suction, this suggests there is a problem with the motor.
Contact your service engineer.

9.2 WHAT TO DO WHEN THE MACHINE WILL NOT SWITCH ON

a) Turn it on again, connect the socket and depressing the button + in x500 model.
b) If the machine has an overload protection device, press the button on the device.
c) Unplug the appliance and wait 30 minutes.
d) Turn it on again and connect the socket.
e) If you still cannot turn the unit on, contact your service engineer.

9.3 WHAT TO DO IF THE PIPES ARE BLOCKED

a) Please read the main points of the User Guide again to check that you have followed the indications
correctly.
b) Turn on the central vacuum unit and adjust the air-flow in the ducting which should impel the
obstruction towards the central vacuum unit.
c) Unplug the central vacuum unit and unfasten the dust container and remove it.
d) Then connect a conventional vacuum cleaner to the inlet valve without suction.
e) If the pipe is still blocked, contact your service engineer.

9.4 WHAT TO DO IF YOU SUCK UP WATER

a) If you accidentally suck up water with the machine, keep the central vacuum unit running for 15
minutes in order to suck up all the water from the pipes and the pipe network.
b) In the event that water has entered the filter and the central vacuum unit, unplug it from the mains
immediately and contact your service engineer.
