Hi,
My sister moved in her first house on Friday. The heating wouldn't work, we thought it was out of oil but about half an hour later it came on by itself, however it was only heating HW not the CH, the only way to get the CH to work is to manually move the diverter valve, the radiators then got hot.
However after about 30 mins of it working, it went off. The lockout light didn't come on, it just turned off. Then it kept blowing the fuse on the boiler circuit board, turned out the water pump in the boiler had broke so i replaced it with a different one and the boiler fired up again. But the CH only comes on if you manually move the diverter valve.
Then after about 30 mins of it working it just switches off, the lockout light doesnt come on. Then after about 1 hour it comes back on by itself. it has been coming off and on like this all night.
There wasnt alot of oil in the tank, but we have since put about 5 gallon in, but it has made no difference
Does anyone know what the problem could be?
The boiler is a Worcester Heatslave 18/25 external oil Combi boiler
Thanks
