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 boiler locks out withing lights flashing in a sequence which suggests lack of burner ignition.
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.
While searching through the various threads I came across a suggestion where this guy turned off the power supply to the diverter valve after it had locked into CH mode. Then he turned on the hot water keeping the central heating switched off. So the tap water will obviously run cold as the heat is now being diverted to radiators. I tried the same thing on my boiler and yup the radiators now get hot and the heating is working as it should.
However this is a temporary measure but it does rule out any pump, gas valve problems. So I am wondering if this means that diverter valve is faulty or is there any other problem which is preventing the boiler to stay lit while using the central heating.
