How can I get my oil based Camray 3 oilfired central heating boiler working?
It is stuck on lockout.I cannot find the manual left by previous house owner. Would it mean that we have run out of oil? Or is it something technical to do with the boiler?
Check the oil level in the tank, if it is empty you have run out. the boiler will probalby require engineer attention to restore to working order once you have a delivery
