Hi. We have an Ariston EuroCombi Boiler at work which has been cutting out all through the winter. It seems to work for about 6-8 hours at a time and then the flame goes out! I had a play with the colck settings yesterday and when we came in this morning it would not come on at all. I reset the clock and used the little hand icon to get back to the setting that it was on before I messed yesterday and it now works however the day numbers on the clock are flashing and I cannot reset them. Can anyone help me set the clock up correctly and does anyone know why it has been cutting out after a few hours?
