Hi I have been to a Biasa combo boiler that the hot water works

Customer Question

Hi I have been to a Biasa combo boiler that the hot water works but the heating will not egnite. The power green light is flashing every second, have tried pressing the reset button but no change.
if reset button is pressed for longer than 10 seconds then the gas flame light comes on (red) and the green power light stays on not flashing.
As I have never worked on a Biasi boiler would be pleased to have any ideas

Hi .i would suspect the heating flow switch , the diverter valve , or the heating thermistor. Also make sure the boiler is getting power from switched live if there is a room stat. Do you nhave the model?
