Hot Water Problem. CH is fine but when i call for hot water the boiler fires up for approx 20 seconds then cuts out, then reignites and then cuts out again following this cycle until hot tap is turned off. I can get hot water but only at a trickle from the tap. If i increase the flow of the water then it goes cold.
Both diverter valve pins operate when water selected
PCB looks fine (No burn marks evident)
Fan runs at full speed.
Pump is whirling and gets hot.
Diverter valve gets hot.
Heat exchanger gets hot.
but cold water outlet pipe from boiler is COLD / LUKE WARM.
Please advise!!!!
