BAXI EcoBlue Advance 33 Combi ErP Boiler Fault Codes

Error Codes

1. If a fault occurs on the boiler an error code may be shown by the facia display.

2. The codes are a flashing number, either two or three digit, preceded by the symbol E :-

- E followed by 20, 28, 40, 160 or 321 indicates possible faulty components.

- E110 and 111 indicate overheat of the primary system water.

- E117 is displayed when the primary water pressure is greater than 2.7 bar. Restoring the correct pressure will reset the error.

- E118 is displayed when the primary water pressure is less than 0.5 bar. Restoring the correct pressure will reset the error.

- E133, indicates that the gas supply has been interrupted, ignition has failed or the flame has not been detected.

- E128 is displayed if there has been a flame failure during normal operation.

- 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°C.

ii) If within 10 minutes of the burner lighting the boiler actual temperature twice exceeds the selected temperature by 30°. In these instances poor primary circulation is indicated.

3. By pressing the 'Reset' button for 1 to 3 seconds when E110, 125 & 133 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.
