In desperation, I trawled the internet and am pretty sure that these are manufactured by Drayton, either a Drayton Digistat +2 or Digistat +3

Try this page http://www.gasapplianceguide.co.uk/drayton_central_heating_controls.htm

Good Luck!

SOURCE: Grundfos installation with Buderus boiler. Pump

Do you have more than one zone? If so, it is difficult to tell if the circulator in question is actually running. A trick is to get a screwdriver and place the metal end on the front of the circ and the other on your ear. You will hear it if it is running. If you do hear it, is the circulator itself very hot to the touch? If it is, it may be burnt out, or the zone needs to be bled of air. Another doubtful, but possible, answer is that the circulator is installed backwards. There is an arrow on it and it should be aimed towards the flow of water.

I have a Worcester 24di combi boiler and it's not working I have a red flashing tap light have represurised the pressure but still not working I have no heating or hot water can you help me please


Red flashing lights usually mean trouble.
There is not enough air getting to the combustion chamber, or the chimney is not working properly. (Stopped up flu)
If this is not a pretty obvious problem, it is better handled by someone who knows a lot more about it than us.

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 a worcester 28cdi combi boiler. The pressure keeps going up yo 3 bar when the heating is on, and venting of via the pressure valve. When the boiler cools down the pressure drops to zero, and I have...


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 )

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.

Not the best day for this to happen.

Check the system pressure and top up if necessary - but after that the best advice is to get the people who fitted it for you to come out and sort it - These Worcester combis usually have a 5 year parts warranty and with a boiler that's just a few weeks old, you oughyt to be able to get the labour for nothing as well. It would be a shame to throw those benefits away by tinkering yourself.
