Biasi M90 24S fails to ignite


My Biasi M90 24S permanently fails to ignite. I can hear that the ignition sequence starts  goes for few seconds and then stops just before sparking. What is wrong and can I fix it myself?

Hi Tim

There are many parts that can be responsible for ignition failure like:  burner, temperature sensors, PCB, different electrodes, cables or even an air pressure switch or a pump. I would advice calling GasSafe registered boiler specialist or Biasi customer service and request a visit/repair. You need someone experienced to fix this kind of issue.
