If this occurs when the unit is in use for only hot water, there will be an internal leak in the secobndary heat exchanger, you will have to replace it. check first that the charging link has been removed when testing to ensure it is not passing.
if it happens when the heating is switched on then check the presure in the expansion vessel ( dump all presure from system and use a car foot pump with a gauge there should be 1 bar presure) that is the big red thing behind the pump, if water comes out of the test valve on the front of it when you try to test it or it wont hold the presure you will have to replace it (a nasty job you have to strip half the boiler) if you can pump it up make sure you release the presure in the system as you pump it or you will get a false reading

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

Your boiler has an expansion vessel that is like a bladder full of air. Yours has lost it's air pressure. Check your manual for this vessel and where the valve is to re-inflate it and what pressure to inflate to. It should have a simple tyre valve, pump it back up (usually to about 1 bar after releasing the water pressure) and should be all fixed. If you can't re-inflate the bladder is holed and the expansion vessel will need replacing.

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 )

Worcester bosch greenstar 25Si?30Si pressure gauge showing high


a couple of things , is your filling loop disconected ? , and are all your radiators blead from air, have you got a high point where the air can get stuck in system say pipes going into roof etc you may need to fit a air release valve in line at highest point to remove the air from system , your boiler should be around 1.5 bar running preasure average setting . if you are constanly filling with water you could be exceeding the pressure valve limet which releases pressure from system this could be faulty ?
