hi
i have a ariston eurocombi boiler a23 mffi, the problem is i can only get hot water when the heating is on but when the heating reaches temp it goes off. should the flame go to low flame when it reaches temp on the boiler instead of going off and then back on when temp drops.
i have plumbing knowledge but not much on boilers, i have changed the D H W and the main flow switch diaphragm but still have hot water problem.
would be grateful if anyone could help me out
thanks nige
