Hi All

I have no DHW or CH from my Ferroli 701 combi boiler.

The fan is running fine, ihave looked at the led status for faults and it gives nothing.

The CH boiler pressure switch is working fine.

The pilot light ignites fine and stays lit so Thermocouple is ok.

The Overheat thermostst is working.
The DHW flow switch is working (led comes on when i open HW tap)
The CH pump is running.

There is a RED led that comes on after about 3 mins and swiyches a relay(RY4) which states 'fan' on the fault finding manual, is this the CH pump ?? As the fan runs as soon as boiler is turned on.

After the red led goes out and the RY4 relay energises i would expect the boiler to light as all comditions are met ?

Anyone got any ideas ?

Thanks
