Please help I have A Worcester 24i not the greenstar type we inherited it with the purchase of the house six years ago there was no information left with it, it has been brilliant up until now. The problem is that there is no hot water I have tried all the usual suspects such as the pressure gauge and this reads 1.5 bar the fan is running but all I seem to keep getting is a red flashing light that has a warning triangle over it I have pressed this as I think this may be the reset button but hence nothing.I have also turned the boiler off at the mains and tried waiting for 10 minutes in the hope the electronic ignition may reboot itself but no result, please help with any information if possible, it would be much appreciated.
