18.0Fault Finding

18.1Initial Fault Finding Checks

1.Check that gas, water and electrical supplies are available at the boiler.

2.Electrical supply = 230V ~ 50 Hz.

3.CH water system pressurised to 0.5 bar minimum when the boiler is cold.

4.The preferred minimum gas pressure is 20 mbar.

5.Carry out electrical system checks, i.e. Earth Continuity, Resistance to Earth, Short Circuit and Polarity with a suitable meter.

NOTE: These checks must be repeated after any servicing or fault finding.

6.Ensure all external controls are calling for heat and check all external and internal fuses. Before any servicing or replacement of parts, ensure the gas and electrical supplies are isolated.

18.2Error 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 regularly further investigation is required.
