Points for Boiler User
Note.
In line with our current warranty policy we would ask that you check through the following guide to
identify any problems external to the boiler prior to requesting a service engineers visit. Should the
problem be found to be other than with the appliance we reserve the right to levy a charge for the visit, or
for any pre-arranged visit where access is not gained by the engineer
.
Troubleshooting – Typical Non Product Faults
Problem
Solution
Boiler is not working for
central heating or hot water
•
Is there power to the boiler i.e. is the left hand side green LED (A) alight and
flashing every 4 seconds. If not this is not a boiler fault – contact the installer
•
Check pressure gauge on boiler shows a minimum of 1 bar
If not re-pressurise via the filling loop to 1 bar (if unsure contact your
installer), turn off the tap on the filling loop and press the reset button (D) to
reset the boiler. If unable to do so or if the pressure continues to drop after
filling then contact your installer
•
Is the lockout signal lamp (E) alight – Press boiler reset button (D) – If boiler
still does not fire contact the installer
Boiler goes through ignition
sequence but will not fire for
either central heating or hot
water and then goes to
ignition lockout
•
Check gas supply (try another gas appliance cooker/fire etc) If no gas
supply then this is not a boiler fault – Contact the gas supplier
Fan & pump run
continuously but there is no
attempt at ignition
•
Check that the air pressure switch test caps, on top of the boiler, are fitted
correctly.
Mini C Only
Operating for hot water but
will not operate for central
heating
•
Check that integral programmer is set to an ‘on’ period and the function
switch is set to ‘auto’ – If it still does not operate contact your installer
•
If fitted with an external programmer check that the central heating channel
is set at an ‘on’ period – If it still does not operate contact your installer.
•
Check the room thermostat is set at the required temperature – Test the
room thermostat by turning fully up – If this does not respond contact your
installer
•
Check the radiator temperature control (C) is set at the winter setting for
central heating.
The nature of all combination boilers is to heat up water directly from the incoming mains water supply directly
through the boiler to supply domestic hot water at the stated flow rates, (as shown in the boiler installation
instructions), to achieve a 35°C temperature rise. As the ambient temperature of the cold main varies during the
summer and winter months it is likely in the colder winter months that the flow rate will need to be reduced at the
outlet taps to achieve the same temperatures achieved in the warmer summer months.
This is not a fault with the
appliance but is relevant to the varying temperature of the incoming cold mains water supply.
Mini S Only
Operating for hot water but
will not operate for central
heating
•
If fitted with an external programmer check that the central heating channel
is set at an ‘on’ period – If it still does not operate contact your installer.
•
Check the room thermostat is set at the required temperature – Test the
room thermostat by turning fully up – If this does not respond contact your
installer
Operating for central heating

If fitted with an external programmer check that the domestic hot water

installer.
•

cylinder thermostat by turning fully up – If this does not respond contact
your installer
