Hi, Im looking for some advice on a baxi combi 80e that has been behaving strangely the past 3 days. firstly we noticed the hot water wasn't as hot as it had been previously (8 years) then the other day we came home and the Radiators were hot even tho we had not had the CH on. then this morning there was no hot water out the taps. I checked the boiler and the led's were lighting up as normal (up to 70degC) when the tap was on but the water from the tap remained stone cold. the boiler would then go off and relight once the led temperature indicators had dropped back to 60degC. So it was behaving as if it was all functioning correctly but no hot water from taps. I turned the taps on an hour later and all worked perfect again. any ideas and thanks in advance. Rick
