7 - DIAGNOSTICS

If the appliance is not working first check the condition of the fuse in the
rear.
If necessary, fit a replacement fuse rated as specified in table 2.1
(technical data).
Before checking the fuse, set the main switch to 0 (OFF) and disconnect
the appliance from the electrical power supply; now check the fuse and
replace if necessary.
After the screwcap has been refitted the power cable can be reconnected.
If malfunctions and faulty operation is persistent, set the main
power switch to OFF, unplug the appliance and consult CARLO DE
GIORGI.
When communicating a fault, ensure you explain the exact nature of
the problem to our technical personnel.
