If the appliance detects a fault, a flashing fault symbol (spanner)
is displayed, possibly together with a fault number.
The appliance differentiates between a fault, where the appliance
continues to operate with limited functionality, and a blocking
fault, where both fans are stopped.
In the event of a blocking fault, the settings and read-out menus
are also switched off and access is restricted to the service menu.
The appliance remains in this fault condition until the problem has
been resolved. The appliance then resets itself (auto reset) and
standard mode is displayed again.

Notify a qualified contractor, who can correct the fault.
A blocking fault cannot be resolved by briefly disconnecting the
appliance from the power supply. The fault itself must first be
rectified.
If you cannot remedy the fault, notify your qualified contractor.
To facilitate and speed up your request, provide the number from
the type plate (000000-0000-000000).
