Hi thanks for taking time out, my son as got to germany with the army and his boiler the worcester 24i junior was working fine, however when you switch it from hot water to heating the boiler cuts out and the warning light starts flashing,if you switch the power off then backon and press the warning light it comes on. What would cause the boiler to cut out when switching it from hotwater to heating,thanks
