The vacuum cleaner will not start

The vacuum cleaner is fi tted with a thermal cut-out that
may have tripped. If this happens - unplug the main
power cord from the wall socket. Wait fi ve minutes to
allow the machine to cool down. While you are waiting,
check the fi lter and dust bag to be sure that nothing is
blocking the fl ow of air through the machine. After fi ve
minutes, plug the power cord back into the wall socket.
The vacuum cleaner should now start again. If the cut-out
trips again, you need to get a service fi rm to remedy
the fault.
• Are you using the correct hose?
Only the original hoses fi t correctly.
• Does the vacuum cleaner start when you try a
different vacuum socket? If so, there is a fault in the
electrical connection to the fi rst socket. Unscrew the
socket and check the connection at the back.
• Is the power supply connected to the vacuum unit?
• Is there power at the socket?
• Is the low-voltage lead connected to the vacuum unit?

10 Troubleshooting

Centix 50 Premium display

The Centix 50 Premium model has a display that shows
relevant status. The display shows the machine’s total
operating hours (Run) It also shows the remaining
capacity of the fi lter and dust bag (Filter / Bag).
* Run: Shows the machine’s total operating hours, ie, the
period of time the motor has been in operation. When the
machine has been in operation for approximately 700
hours, it stops. You must then make immediate contact
with an authorised service workshop for a replacement
motor to be fi tted. You can reset the machine temporarily
and run the motor for an additional 100 hours
(approximately) by unplugging the power cable and then
reconnecting it to the mains socket. Once you reach the
end of the 100 hours of operating time, the machine will
stop again. It will now be necessary for an authorised
service workshop to replace the motor and reset the clock.
* Filter/Bag: Shows the remaining capacity of the
dust bag and bag fi lter. The indication is shown as a
percentage. 0% is displayed when the bag/bag fi lter is
empty. Indication is then given in increments of 10% at a
time. When 90% capacity has been reached, the display
will warn you with the following fl ashing message: Check
fi lter. You should then check the ��� lter and replace the
dust bag and bag fi lter as soon as possible; see section on
fi lter and dust bag. Once the dust bag has been replaced,
reset the machine by starting it up again. The indication
should then display 0% again.

Service and spare parts

If you need a service or spare parts, contact your local
dealer. In such circumstances, it is always useful if you
can give the technical data shown on the rating plate of
the vacuum unit. The rating plate is adjacent to the lead
intake. It’s a good idea to copy this data here so that it is
readily to hand.
