Hi,
I have recently had some problems with this combi and have changed the CH pump. It operates fine and I can hear the water going through. The system was completely emptied and refilled.
I have noticed that whenever it has been emtied it takes ages beore the hot water starts to circulate even though the pump runs from switch on. This is when it is simply switched to constant. In the past it has taken hours before it starts.
I have noticed that the burner comes on as expected and then after a few minutes stops (presumably because the internal tank has reached temperature).
My first question is, how long should it take for the hot water to start circulating after it has been switched on at the mains and set to constant?
Would I be correct in thinking that if the diverter was stuck it may not allow hot water to enter the CH system? How can I test the diverter? I am assuming it is the thing behind the control panel box with two wires connected to it and about four or five pipes. One of these pipes (a silver one that comes from higher up in the boiler) is actually hot which presumably should be being diverted to the CH system.
In all cases the hot water works fine. If I remove one wire from the diverter solenoid the hot water still works. Is this correct or a sign that the diverter is stuck?
