I have a Ferroli Optima 701 boiler which is not producing hot water. CH works fine.

When I have the hot tap running I have LED's 1 and 4 ON which is OK
However, LED's 2 and 6 are OFF.
This leads me to believe that the DHW flow meter is faulty. To check this I turned the CH on and then turned the hot water tap on. Under Section 'B' I should get a warning LED with 2 ON. This does not happen so this probably confirms the flow meter.
Does anyone agree with this or is there a possibility that it is something else?
I swapped the wires for the temp sensors of CH and DHW over to check if it was that but it made no difference. (Changed the CH sensor a year or so go as it was faulty)
Cheers for any help!
Dave
