Hi, I am currently facing some problems with the Biasi M110.32SM/E where the hot water works fine ( the boiler sometimes goes in lock out mode) but the central heating just does not work. I turn on the central heating the boiler recognizes this and fires up but only for two seconds and then the fire disappears but the boiler continues as though heating is working. The boiler attempts again to fire but the same cycle repeats.
I have checked the thermostat and that seem to be ok as I hear the click noise when turning it to higher temperature. In addition I have also checked the electric actuator which seems to be working fine (however I am not sure if the divereter vale itself is working or not). The pump I think is working as it is also needed for DHW. However when i switch either the DHW or CHW I do hear gurgling noise which I thought was due to air trapped inside. So I have gone ahead bled the system to best of my abilities and the noise has reduced significantly.
So now that you have read wall of text I would like your support in fixing this problem and if its not a DIY how much would it cost me to replace parts and get it fixed.
