    Same happened to me yesterday, after frantically getting worried and calling British Gas to see if I was within my Guarentee (I was not) a handy and helpful Gas Engineer friend suggested that I pour 6 kettles of boiling water on this codenser pipe (white) out in the garden. This had frozen and clogged the system up. After half hour, I reset the boiler and it was working again.

With almost every heater you can reset them by either turning the thermostat all the way back or turning the power off for a minute or so. Then turn the t-stat back up or the power back on tto get them to retry to light.

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.

Oil furnace only produces cool water intermittedly and only when heat is actively on


For clarity, a Furnace produces HOT AIR for heat while a boiler produces HOT WATER for heat. Just remember...boil = water. You said your "furnace" does not produce hot water for a shower and because furnaces do not product hot water unless they have some model that do???? Usually people with a furnace have a seperate hot water heater. People with boilers though can produce hot water for use as both their sinks/showers hot water and their heat (by heating water that goes through baseboards) in their house. I don't believe any furnaces produce hot water most of the time a furnace just produces hot air for heating. So figure out what you first have.
Having said that, I'll assume you have a boiler like I do and my Weil McClean(sp?) stopped working a while back and wasn't turning on to "boil" any water. I took apart the burner and there is a light sensing photo resistor as part of the controls. If this phto resistor goes bad, the boiler will not start. The resister is cheap, I think it was $8 but you have to know what you're doing to change it. So you may be better to call someone who can work on such equipment.
Boiler's themselves are not overly complex. Home heating oil is the same diesel fuel that you can buy in a gas station only the government has "oil" companies put a RED die in home heating fuel which is usually cheaper then Diesel fuel because diesel fuel is taxed to death. The reason they do that is so that if you try putting RED tinted home heating fuel in your truck and you get pulled over (because you're a trucker with and 18 wheeler and they typically do inspections of these trucks) you will be a huge fine if they see you're running home heating fuel and NOT paying your taxed by purchasing Diesel fuel. A little bit of background so you know the fuel you are dealing with here. So it's dieslel fuel without the tax you run in your boiler. Gasoline on the other hand is VERY explosive as you know, but diesel fuel (if you're ever tried to light it) takes some coaxing to get lit. When it's cold out, diesel fuel is very hard to light and that's why trucks use glow plugs. You don't need those in your home though.
But because diesel fuel/home heating oil is hard to light, it's sprayed as a msit into your boiler, so that it can light more easily.
But because it is a fuel, you should know what you're doing when messing with it. FInd out what you have, and then have someone work on the issue if you haven't already. I'm guessing you have had it fixed by now?

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.
