Troubleshooting table
Malfunctions can occur in all electrical appliances. This does not necessarily mean
there is a defect in the appliance. For this reason, please check the tables to see if you
can correct the malfunction.
WARNING
Risk of electric shock in case of improper repair!
Never try to repair a defective or suspected defective appliance yourself. You can put
your own and future users’ lives in danger. Only authorised specialists are allowed to
carry out this repair work.

tioned correctly.

Circulation air oper-
ation:

equately removed;
weak airflow.

clogged.
Clean the grease filters and/or replace the
activated charcoal filters (starting at page
GB-18).
Exhaust air operation:
Poor performance.
The exhaust hood
does not have a suffi-
cient air supply.
The exhaust hood expels a large amount
of exhaust air. This is why you need to pro-
vide a sufficient air supply, e.g. by providing
non-sealable openings in doors, windows
and ventilation conduits.
Note the safety notices starting on page
GB-4.
The exhaust air hose
is bent or too long.
Check whether the exhaust air hose is bent
or too long.
