with the boiler set to CH and Water and on the timer setting. When the hot water tap was turned onI did not hear the boiler click and could feel the water going through the water pipes but did not get hot. The central heating pipes did seem to get hotter instead. Also for more info the first 4 red lights are on on the control panel.
It has been like this since friday night but we manged to get by with a luke warm shower yesterday. it just does not get hot enough now for that.
