Bosch WORCESTER HEATSLAVE 12/14 User Instructions & Customer Care Manual page 11

HARD-WATER AREAS
If you live in an area where the mains water is exceptionally
hard, it is recommended that an in-line scale inhibitor is used in
your boiler and system, in strict accordance with the requirements
of your local water company and bye laws. An isolating valve, to
facilitate servicing, should also be incorporated.
Water hardness can be determined by reference to your local
water company. Further information can be obtained from
Worcester Heat Systems.
FAULTS & BREAKDOWNS
Many calls made to Worcester Heat Systems to report boiler
faults or breakdowns prove to be false alarms, as there is often a
simple explanation for the apparent malfunction.
So, to help you save time and money - not to mention
frustration and inconvenience - a quick-reference fault finder is
included on page 12.
If, after checking through the points suggested, there is still a
fault, you should call your local Worcester Heat Systems Service
Centre. Arrangements will be made for an engineer to call as soon
as possible.
CALL-OUT CHARGES
All of Worcester Heat Systems' field service engineers are
factory trained.
If you request a visit from an engineer and your boiler has been
installed within the last 24 months, no charge will be made for
parts and/or labour providing:
●
The appliance was commissioned correctly on installation
and a completed Guarantee Registration Card returned to
Worcester Heat Systems.
●
An appliance fault is found and the appliance has been
installed within the past 24 months, provided that the first
annual service has been carried out on a boiler which is more
than 12 months old. Reasonable evidence of this must
be supplied on request.
