Hi,
I'm having central heating problems (Glow Worm Ultimate 50FF) which initially began with no CH (plenty of HW) in cylinder. On closer inspection the overheat cutout button on the bolier electrics had triggered. When reset if fired for 1min then cutout again. This happened repeatedly.
I called out a plumber (under an insurance policy) who changed the pump and then said there was no circulation. He had inspected feeder tank in loft and said it was full of sludge, therefore, he thought this was the cause of the blockage. He told me this wasn't covered under the warranty and anyway he could'nt stay to fix it now. At least I have a nice new pump I didn't need
I've tried draining the system and clearly not all water is exiting from the system so there must be a blockage. Cleansing chemical has now been added in desperation BUT my boiler is now doing NOTHING. No fan, no pump, no wall stat or tank stat triggering ... just silence, though there is power getting to the circuit board! Could the electronic board have been damaged by resetting cutoff switch regularly whilst trying to diagnose problem or is there a sensor somewhere I'm missing which sets the whole sequence of events which lead to the boiler functioning?
As an emergency measure I have wired in an electric immession heated so I can at least have a bath for Christmas
Any suggestions appreciated. Merry Christmas one and all.
