Check the condenser trap. I have a Worcester boiler and that kept cutting out just before Christmas. The trap was gunged up so boiler refused to run. My plumber couldn't call as he was off on hols but he talked me through cleaning it. Relatively simple. It is usually cleaned at annual service but overdue this year due to a house move. Cleaned and replaced and boiler back working.
Annual service done as soon as he got back.
