8. TROUBLESHOOTING
WARNING
When carrying out repairs and cleaning the device, the plug should always be removed from the
wall socket before the device is opened.
Preface
Before searching for the defect, check that all parts are in their correct position. To do this, remove
the device’s rear plate and check that all printed circuit boards, connectors, wire beams and pipes are
mounted correctly.
After carrying out a general parts inspection, use section 8.3 Troubleshooting analysis to verify the
probable cause of the problem.
#) If the column solution advises replacement of the part concerned, there is always the possibility
that the defect may be caused by another problem. The functioning of the device should therefore be
thoroughly tested to make sure that the defect does not reappear.
