ROUBLESHOOTING
Repairs must be carried out by an authorized specialist in compliance with applica-
ble safety codes and regulations.
Improperly executed work will put your safety at risk!
Note that some work must only be carried out by an electrical specialist. According to DIN EN 60204-1:
2011-01, specialists are „persons who by reason of their relevant training and experience are capable of
recognizing risks and avoiding potential hazards."
Some malfunctions you may be able to remedy yourself. Always check first if the problem is due to an oper-
ating error. Repairs are not free of charge, even within the warranty period, if the problem is caused by an
operating error or if you have failed to observe any of the following instructions.
Before any cleaning, maintenance or repair work is carried out, the appliance must
be disconnected from the mains and de-energized. To do so, it is not enough to set
the power switch to OFF. Instead, the mains plug must be pulled or the electrical
circuit must be de-energized, respectively. Check that no voltage is present before
opening the appliance, and lock out the circuit to make it safe against re-energizing.
Work at the electrical installation must only be performed by qualified
electricians!
Maintenance and repair work must be carried out only by qualified professionals
using original spare parts and accessories. Do not attempt to carry out repairs on
this appliance yourself!
