Fault codes
1. If a fault occurs on the boiler an error code may be shown
by 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'
E20, E28 & E50 indicate faulty or incorrect components.
E110 shows overheat of the primary water and E130
overheat of the flue system.
E119 is displayed when the primary water pressure is less
than 0.5 bar.
E133 indicates that the gas supply has been interrupted,
ignition has failed or the flame has not been detected.
E125 is displayed in either of two situations:-
i) If within 15 seconds of the burner lighting the boiler
temperature has not changed by 1°.
ii) If within 10 minutes of the burner lighting the boiler
temperature twice exceeds the selected temperature by 30°.
In these instances poor primary circulation is indicated.
3. By turning the selector switch to the 'Reset' position for a
minimum of 5 seconds when E110, E130 & E133 are
displayed it is possible to relight the boiler.
4. If this does not have any effect, or the codes are displayed
