Boiler keeps turning off: possible reasons

A boiler that repeatedly stops may be responding to low pressure, poor circulation, overheating, controls or a recorded fault.

Likely causes

  • Pressure loss, thermostat demand, frozen condensate, pump or sensor problems can interrupt operation.

Safe checks you can make

  • Record the display code, pressure and whether hot water or heating triggers the shutdown.
  • Check only normal user controls described in the manufacturer instructions.

When to stop and get urgent help

  • Do not repeatedly reset a boiler that locks out or shows signs of overheating, leaking or unsafe combustion.

How a Gas Safe registered engineer can help

  • A Gas Safe registered engineer can read fault history and test combustion, controls and circulation.
