we are havng trouble with a 7 year old Biasi M110.32ME combi, the heating works OK but the hot water will only run for a few minutes and then locks out, if the lock out is reset it will do the same thing again and the water does not get up to the temperature set on the control at number 4.
Help or advice please.
Hi, it sounds like it is overheasting within the hot water circuit within the boiler . there are two possible causes. The domestic heat exchanger is blocked and will need cleaning or replacing ,or the hot water temperature thermistor ( thermostat ) is faulty and will need replacing
