16 Trouble-shooting
Despite being expertly designed, the machine may develop minor faults which are usually
easy to eliminate. This section explains a number of possible problems and how you can
deal with them yourself.
Before carrying out work on the open appliance, it MUST be disconnected from the
power supply. The machine is to be switched off completely with the on-site power dis-
connection device here.
Should any of the operational faults described arise repeatedly, their cause must be
established in each case.
Faults not described here can in general only be eliminated by a technician or electri-
cian. Please contact the agency responsible or the authorised dealer.
