I have a Worcester Bosch 240BF Combi Boiler. Apart from changing the rubber diaphragm of the diverter valve I’ve never had a problem.
Last week I was getting no hot water. The only way to get hot water was to run the hot water tap, and flick the hot water switch on for the boiler to fire up (the boiler would stay fired up even when the tap was turned off, and all my radiators heated up even without the heating on). The advice I received was that the complete diverter valve needed replacing.
So, the whole diverter valve has now been changed and when I turn the hot water on, the boiler fires up as normal, and with turning the tap off the boiler fires down. So great….
But now when the tap has been running for a couple minutes, the boiler makes a bit of a banging noise, water shoots out of the overflow outside, the boiler fires down and the pilot goes out!
Help please!
