More than 30% of all calls made to Worcester Heat Systems to

report appliance 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 – please refer to the General Information, Notes and
Lighting Instructions ensuring all controls are set correctly.

If, after following the instructions the appliance still fails to oper-

ate correctly call your local Worcester Heat Systems Service Centre.
Arrangements will be made for an engineer to call as soon as possible.
