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
