POINTS FOR THE 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
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 set
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.
Problem
Solution
Boiler is not working for
central heating or hot water
•
Is there power to the boiler – check by switching the boiler 'ON/OFF' switch (A) off and then
back on. The lights (E) should flash. If not this is not a boiler fault - contact the installer.
•
Check pressure gauge on boiler (D) 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 carry
out ignition restart sequence detailed under 'Faults'. If unable to do so or if the pressure
continues to drop then contact your installer.
•
Is the fault indication light (2) alight - see Reset Procedure under 'Faults'.
Fan and pump run
continuously but there is no
attempt at ignition
•
Check that the flue product test cap, on top of the boiler is fitted correctly.
Operating for hot water but
will not operate for central
heating.
•
Check that integral programmer (if fitted) 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 CH thermostat knob (B) is set at the winter setting for central heating.
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 gas supplier.
F a u l t s
No heating or hot water
Check that gas and electricity are available at the boiler and
that all switches are on.
Check that the system water pressure gauge (D) reads at least
0.5 bar.
Reset Procedure
Check the red fault indication light (2). If it is illuminated turn
the main switch (B) to '0', wait until the boiler reaches standby
state, indicated by no fan or pump running. This can take up to
10 minutes in an overheat condition. Turn the main switch (B)
to the winter setting wait for 2 seconds then set the main switch
(B) back to the desired position to restart the ignition sequence.
Hot water but no heating
(winter setting)
Check that the programmer and room thermostat (if fitted) are
both calling for heat.
Heating but no hot water
Check that cold water flows out of the taps at a minimum rate of
3.5 litres per minute (or 1 pint in 10 seconds or less). If not,
look for stop valves not fully open.
If these simple checks fail to solve the problem, or the
problem recurs, consult your service engineer.
