Help!!
I've got a problem with a microgenus 11 31 MFFI (not the condensing combi). The combi shuts down before room temp. is reached. the room 'stat is set to 21c but the boiler shuts down while the rads are cool. The boiler will sometimes fire up again and the cycle will start over but mostly the combi locks out showing a "A01" fault and has to be reset but, again, does not reach room temp. I checked max. and min. gas pressures and the gauge showed fluctuating gas pressure readings and you can also hear the gas valve solenoid operating with an intermittent "pinging" or ticking sound. I thought it was a flow problem but the pump is operating ok. Dom.hot water is ok and the boiler is about three years old. Any help or advice will be greatly appreciated.
thanks.
