no heating/hot water (Worcester Greenstar 24i combination boiler)?

We have Greenstar 24i Junior combination boiler - but this morning as soon as i walked into bathroom knew something was wrong - it was freezing, no hot water or heating - reset button flashing red and fault indicator (blue light) flashing, also pressure gauge was on red - have added water and pressure back up. tried to reset but lights still coming back on, have noticed burner indicator light not on, so have followed instructions which says hold reset button for 2 seconds but still no change - also poured water on condensation pipe, ice then water came out - tried to reset again but same lights still showing, any suggestions would be very grateful - cheers

I am one of 3 people I know that have suffered the same problem in the last few days with the same boiler. It does seem to have something to do with the condensor pipe freezing up. Our boiler is on the first floor so its not very easy to get the the external pipe-work. My quick fix has been to run a hot tap, hold the reset button for a couple of seconds, then release, leave the hot tap running for a few minutes more(the water should be running hot by now), then turn the tap off. This seems to allow the boiler to keep running long enough to clear the frozen pipe after which it works fine. Hope this helps.

thanks for your answers, we think it must be the gas as had probs with the only other gas appliance (fire in living room), did place call with British Gas this morning and soonest they can come out is Wednesday afternoon. Family have come to rescue with couple of electric heaters, and will keep boiling kettle for hot water. cheers again.

disconnect the condense pipe inside close to the boiler you may not have toally cleared the ice you cant leave it that way but at least you will know also have you lost the gas supply to the house for any reason or are other gas appliances struggling with low pressure this could cause boiler lockout may need an engineer to verify my second thought
