Worcester Bosch 28i - the hot water side work ok, but when I put the heating on, the ignition red light keeps flashing, any advice on what I have got to do. I have checked the pressure and the pressure is ok. HELP
remove the front cover,switch off power you then have to remove the big silver panel if you look up top right crner you should see a fan with two small pipes coming from it.it is likely that one of them is cracked that causes it to malfunction
