Hi,
I have an issue with this Boiler the Pump Proving pin is not rising. (One on top of the Diverter Valve)
I have Rebuilt the Diverter valve. Cleaned the bypass pipe.
When i turn the Water on the pin does not raise But the Hot water Priority one does come out. If i push the micro switch on the top of the diverter the boiler fires.
Could it be the pump? The pump is spinning.
Or Anything else as got no hot water and feeling a bit of a hermit stuck in our boiler cupboard
Thanks in advance.
