Hi, I would be really grateful if someone can help. I have a fairly new Baxi 133 HE plus boiler that keeps overheating. The boiler will run all day long heating the house up, but will lockout in over heat when running the hot water. I don’t know if this is related, but the pressure gauge will move from between the ¾ when cold to the 2 ½ mark when it locks out. All the radiators and the boiler have been bleed, although the water that comes out does look cloudy until it settles. It works fine when the heating has not been on for a while? Thanks.
