Baxi 100e Combi boiler switches off repeatedly

Hello Folks,

My Baxi 100e Combi boiler is switching itself off repeatedly like after every five-six minutes. The most important thing to consider is that I bought the boiler one year ago. I have restarted the boiler many times but no success. What should be done for rectifying the problem?



Hi Paul, normally this problem arises due to the three below-mentioned common reasons such as:

  • Your Baxi boiler is dripping
  • I would advise checking the boiler’s pressure relief controller because; you can face this issue when it is damaged or broken. Try to replace it immediately after getting help from the boiler engineer, if this is a case.
  • Apart from all this, another challenging thing is a broken thermostat, as because of this, the Baxi boiler cannot identify the temperature of the water. On the other hand, your boiler will keep switching itself off repeatedly, to prevent it from overheating.
