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.
