Hi Violet - there are different meanings to the different blue flashing light sequences on Worcester boilers. Best thing to do is try to find the instruction manual for the boiler and then check the troubleshooting section to see what your flashing light means. If you can't find the manual, you might be able to find the model (e.g. "Greenstar 30Si") written somewhere on the boiler - on mine it's written in the middle of the multicoloured Energy Rating sticker on the front. Once you know the model, you can download the right manual from https://www.worcester-bosch.co.uk/support/manuals-and-brochures/boiler-user-manuals
