    Hi
    Could someone help me as to what could be wrong with my boiler. it has started to lock out at random times it fire up when then stops then fires back up immediately really no pattern to it. We have changed the thermostat 2 years ago to a wireless one could this be the problem. we have had a plumber out to it but typically it ran with no problem. please could someone advise what it could be.

    just to add to this it seems to happen more when the hot water and heating are on together.

    The photocell is faulty or is not completely seeing flame. The flame is not stable. The control box is faulty. The fuel pump is not giving a consistent to the nozzle. The nozzle has developed a fault. The baffles are too restrictive and the air supply is not sufficient. If balanced flue, a leak from the flue pipe to the air pipe is contaminating the combustion air. Take your pick.
    When it relights , does it actually light, or just purge before lockout.

    As above, can be one of many things.
    Best to get a proper oil boiler service person to fix it

    yes it relights and will run for until the room get to temp but if we run the water with the heating it will lock out.
