I have a homecare agreement with them so am covered. Just a bit strange its happened 2 days after a new diaphragm fitted. I'm a bit worried something else will happen 2morrow when H.E is fitted !
seen quit a few plate heat ex go. especially these ways. due to soft water. also other common faults i find are aps. fans, EVs. divertors. isolation valves if you look at them. actually cant think of one thing on the design these boilers are good to work on. except the NTCs. good old WB designing. hmm WB CDI versus a VAILLANT of the same era e.g turbomax. know which one id prefer to work on still.
AAAArgh I spoke too soon on this thread - see my comment 23rd May.
Following the Heat Exchange plate being replaced about a week ago, the boiler has a slight drip coming from around the bottom right. The pressure was at normal 1.25 but is very very slightly lower but basically still OK. Any ideas anyone ? Oh by the way, the previous week Brit Gas fitted a new diaphragm and Pump & seal. The day afterthat the HE suddenly pinholed. Since the new HE has been fitted, this leak has started.
