Had a Worchester 24i junior/28i junior(not sure which one) installed in January 2010. No hot water this morning and flashing blue indicator fast on front panel of boiler, pressed the reset button and nothing happened, bar pressure is fine, but is the boiler light (green i think) supposed to be lit isn't. Can anyone help rather than having to call a man out on England football match day. When i pressed the reset button the flashing stops after a few mins but then when turn hot water tap on, still cold and starts flashing again.
