Buderus GB142/45 boiler keeps locking out

Hi Everybody,

My three years old Buderus GB142/45 boiler is locking out a lot from the last three days. I have restarted the boiler in order to make it work again but all in vain. I am quite worried, as I have not faced this issue earlier. Please help me by sharing your precious views

Looking forward


Hi Ben,

A common problem with the Buderus boiler is a low pressure, which leads towards boiler lockout. The two main reasons behind it are:

  • Leakage in the boiler’s central heating system
  • Faulty pressure sensor

Depending upon the actual cause and current condition of the boiler it is better to call a proficient boiler engineer, as you cannot solve the problem on your own.
