I have a baxi solo 3 PFL 70 boiler. It was very noisy yesterday, sounded like someone drilling. When I lowered the thermostat on the bolier, the noise was decreased by 50%. By evening, the electricity supply was tripping every 10 minutes, so I swited the bolier off overnight. I switched it back on this morning and the boiler light comes on, the fan light comes on (with no noise) but the pilot light does not come one. How do I get the pilot light on? What could have caused the loud noise? Please help!!!
