My Worcester green star Ri boiler still functions, ie; heats hot water even though timer/control is off for both HW & CH. No 'blue light' fault indicated
Any thoughts? Cylinder thermostat maybe or something external to boiler?
Hi , if you have an independent clock, can you take the front off and just leave the wiring back plate? If the boiler keeps going it is a boiler issue if it stops, a clock issue
