I havnt had hot water for a couple of days and the circulation pump has been sounding a bit ropy and jamming for a few weeks so thinking its because it hasnt pumped enough heated water into the tank I ordered another one (DAB VA65/130) although the new one was an EVO model?!?! anyway fitted it and fired up the boiler (Glow Worm 18hxi) and after a few seconds got a F10 on it, tried a few more times and got the same. Put the old pump back and that now gives an F24.
Any ideas whats going on?
