Fault Indication
1. If a fault occurs on the boiler an error code may
be shown on the facia display.
2. The codes are either two or three digit,
preceded by the letter 'E'. For example, code E133
will be displayed by 'E1' alternating with '33'. E50
is shown as 'E' then '50'.
3. E20, E28, E50, E125 & E160 indicate faulty
components. You should make a note of the
displayed error code and contact your installer or
service engineer.
4. If E110 or E130 is displayed overheat of the
primary water or flue system has occurred. Turn
the selector switch to the reset position and hold
for at least 5 seconds. If the boiler does not relight,
or the code is displayed regularly contact your
installer or service engineer.
5. E119 is displayed when the primary water
pressure is less than 0.5 bar. After repressurising
the system the boiler should operate. Your
installer will be able to advise you about the
method of repressurising. See page 6 for further
details.
6. E133 indicates that the gas supply has been
interrupted, ignition has failed or the flame has not
been detected. Ensure that the gas supply has not
been turned off, and turn the selector switch to the
reset position and hold for at least 5 seconds. If
the boiler does not relight, or the code is displayed
regularly contact your installer or service engineer.
