SERVICE WARNINGS AND FAULT DIAGNOSIS
Your boiler is fitted with an intelligent fault diagnosing system and is able to detect various fault
conditions. Some of these are less serious and the machine will continue to operate as normal, while
others are more serious and will disable the unit.
Before calling for service, switch the machine off at the mains supply. Draw-off a small amount of
water and then switch back on after 10 minutes. If the fault does not clear, call technical support for
advice.
