SIMPLE FAULT-FINDING

Should the boiler fail to start for any reason, please make the
following checks before calling a service engineer:
(1) Is the green light illuminated?
No.
Check for a blown fuse or thrown power-breaker.
Yes
(2) Is the 1 st red light illuminated?
No
Check to see if all external controls, such as a room
thermostat or programmer, are operational and calling for
heat and proceed to (3).
Yes
If the light is permanently illuminated, switch off all power to
the appliance for at least 30 seconds. This should reset the
boiler and return it to normal operation. If the problem
persists, then a fault has occurred. Please contact a service
engineer for assistance.

If the light is flashing, this indicates that a fault has occurred
with the heating elements. As it contains 2 elements, in this
case the 4kW model will continue to operate safely at a
reduced output. As the 2kW model only incorporates 1
element, the boiler will not operate.
In either case, a fault has occurred. Please contact a service
engineer for assistance.
(3) Is the 2 nd red light illuminated?
Yes
This indicates that the system pressure has dropped to
below 1 bar. Check the system pressure and, if necessary,
re-pressurise to above 1 bar.
No
If all system controls (room thermostat/programmer) have
been checked, please contact a service engineer for
assistance.
IMPORTANT NOTE: Electrical safety checks should only
be carried out by a competent person.
Refer to page 16 for after-sales service information.
