The storage of water at high temperatures and the characteristics of the water itself can cause a layer of scale to build up on the surface of the electric heater and/or the accumulation of detritus in the interior of the tank, affecting mainly:

• water quality
• power consumption
•  appliance functionality
• appliance service life

Amongst other things, the abovementioned consequences lead to a lower thermal transfer between the heater and the water, causing the thermostat to start/stop more frequently, higher power consumption and potential safety activation if temperature limits are breached (manual resetting of thermostat necessary).
For optimal functioning, the following recommendations are made:
▶ Clean the interior of the tank.
▶ Clean the electric heater (descale or replace).
▶ Inspect the magnesium anode.
▶ Replace the sealing collar of the flange.
** The above mentioned interventions are not covered by the appliance warranty.

Environmental protection and 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 countryspecific 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 besorted by composition and passed on for recycling or disposal.
Old electrical and electronic appliances
This symbol means that the product must not be disposed of with other waste, and instead must be taken to the waste collection points for treatment, collection, recycling and disposal.
The symbol is valid in countries where waste electrical and electronic equipment regulations apply, e.g.
“European Directive 2012/19/EC on old electronic and electrical appliances”. These regulations define the frameworkfor the return and recycling of old electronic appliances that apply in each country.
As electronic devices may contain hazardous substances, it needs to be recycled responsibly in order to minimize any potential harm to the environment and human health.  Furthermore, recycling of electronic scrap helps preserve natural resources.
For additional information on the environmentally compatible disposal of old electrical and electronic appliances, please contact the relevant local authorities, your household waste disposal service or the retailer where you purchased the product.
