    went away on hols for a week so turned the program off but left power to the boiler, got back put the programmer on and after 2-3 mins it locked out, reset it a few times with no joy, called local plumber out, he didnt really know what was wrong but noticed that when he took the top off there may have been a long term weeping affecting a circuit board? he said it may be expensive (always is) has anyone else had to have this circuit board replaced??

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.

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 )
