A fault, what to do?
WARNING:
Attention!
Repairs must only be carried out by an authorised technician. Improper
repairs can lead to risk of serious injury to the user.
If your appliance does not operate as required, it is often due to a very
minor problem. Please check whether you can remedy the fault yourself
by using the following guidelines. You will save yourself the costs of an
unnecessary visit by customer service personnel.
If the fault could not be eliminated, please call customer service.

Environmental protection/disposal
Environmental protection is a fundamental corporate strategy of the
Bosch Group.
The quality of our products, their economy and environmental safety are
all of equal importance to us and all environmental protection legislation
and regulations are strictly observed.
We use the best possible technology and materials for protecting the
environment taking account of economic considerations.
Packaging
Where packaging is concerned, we participate in country-specific
recycling processes that ensure optimum recycling.
All of our packaging materials are environmentally compatible and can be
recycled.
Used appliances
Used appliances contain valuable materials that can be recycled.
The various assemblies can be easily dismantled. Synthetic materials are
marked accordingly. Assemblies can therefore be sorted by composition
and passed on for recycling or disposal.
Used electrical and electronic appliances
Electrical or electronic devices that are no longer
serviceable must be collected separately and sent for
environmentally compatible recycling (in accordance with
the European Waste Electrical and Electronic Equipment
Directive).
To dispose of old electrical or electronic devices, you
should use the return and collection systems put in place in the country
concerned.
Batteries must not be disposed together with your household waste.
Used batteries must be disposed of in local collection systems.
