Environmental protection and 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 framework for 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.

Test procedure/Cause
Action
Check if water is possibly being
drawn from the DHW cylinder
constantly due to a leak or taps
being open
If water is being drawn constantly,
take action to stop this
Check the position of the hot water
temperature sensor; it may be
attached incorrectly or suspended
in the air
Position the hot water
temperature sensor correctly
If the DHW priority was deselected
and heating and DHW are running
in parallel, the boiler output may
not be sufficient
Set DHW heating to "priority"
Check whether the heating coil in
the cylinder has been vented
completely
Vent if necessary
Check the connection pipes
