Turned on the heating and water on the poiler both lights on, result boiler power light on and boiler starts okay. But after about 40 mins the power on light goes out and and the heating and water lights are still on but the boiler had turned it self off. Result was hot water but rads cold, therefore emptyed the hot water tank and set the 3 way valve to manual and switch heating and water backon. Result rads getting warm but after 20 mins lockout occured therefore pressed reset on boiler and
switched heating and water on again all okay. But after about 20 mins boiler power on light has gone out and the boiler is quiet ?
Have tryed increasing the temp dial on the outside of the boiler but this does not have any result. The room stat is set to 25 and is only about 2 years old.
Boiler : Worcester Danesmoor 20/25
Have just emptyed the tank again and the boiler has started ? Looks like it it not understanding the room stat ?
Have just emptyed the tank again and the boiler has started. Therefore have turned off the hot water and the boiler has stopped ? But the heating light is set to on ? So turned off the heating and turned on the water, boiler running have left 3 way valve at manual to get some heating on.
