Thanks for that mike, it is a worcester bosch combi 24cdi heating and water can stay on for an hour then everything goes off and the red light flashes. it will come straight back on when reset, but then...


Check the pressure reading, should be about 1 bar when system is cold. Various models in the range of 24cdi. If you do not have a manual, go to,
http://www.centralheating.co.uk/Boiler-Manuals/worcester-bosch-boiler-manuals/worcester-bosch-discontinued-boiler-manuals.
Get the manual for your unit, to wards the end of install manual it has a fault finder, Also has a basic 1 in the user manual. Number of flashes how fast the light flashes which one flashing can all mean different, So get the manual and check, Some parts are easy to fix, as long as you do not touch the gas side the rest is plumbing. Come back if needed.

I have worcester combi boiler 24CDI RSF, the boiler will not ignite, for the hot water or the central heating, it was working ok, and the red water light is flashing


i think the fan may be stuck. you will need to gain access to the internals of the boiler so a gas safe engineer will need to be employed to do it. if it is the fan, a simple squirt of lubricant will free it and give you anything from a week to a year of trouble free operation but! you will need to get a new fan. Fit a new one as soon as you can as they tend to go at the worst possible time if you dont

Lighting the pilot light on a Worcester 24CDi combi boiler.


Most of these boilers don"t have a permenant pilot light they have electronic ignition that lights the burner when you are calling for heat or hot water, is there enough water pressure in the boiler ( there is a small gauge on the bottom r/h side of the boiler the needle should be sitting at between 1 - 2 if not enough pressure the boiler won"t light )

Flashing red light on Worcester 24i junior combi boiler


Pressure is ok? at 1 bar or above
I think on this one there should be a reset button [red] on the left hand top of the casing - or lower the control panel [ phillips screw on each side] and the button is on the left of the base plate. Press this and try the heating.or hot tap
P.S. if you're on a prepayment meter check you have gas.
