had the boiler and c/h system installed for about 3 weeks now, have not been using the c/h for 2 weeks, fired it up last weekend, working fine, yestrday heard high frequency ticking sound from the boiler, but it was still working. later on in the day all hot water went off - the boiler would not light atall.(no c/h or h/w) this morning the boiler lit for about 5 seconds (when i turned a tap on) then went off and wouldnt light again atall. I had the c/h turned on too and again it lit for about 5 seconds then went off. (so no c/h) any ideas what this might be ?? - a local agent told me the pump might be jammed.
thanks in advance.....
