Operating errors

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.
Always de-energise the system before carrying out work on the open appliance.
Switch the appliance off completely via the on-site circuit breaker.
Should any of the operational faults described arise repeatedly, their cause must be
established in each case.
Faults not described here can generally only be resolved by a technician or electrician.
Please contact your factory representative or authorised dealer.
