• Boiler Failure

    Unfortunately, complete boiler failure

     a common problem.

    Some Causes of boiler failure can vary wildly from a crack in one of the boiler’s cast iron (or aluminium)

    sections to a broken seal on the boiler pump.o we’ve outlined some common problems and advice on how to get your boiler up and running again.

    Power supply 

    power supply on? If not, you’ll need to contact your electricity supplier.Is the boiler gas supply on?

    Gas Supply

    The gas stopcock is on

    but no gas is coming through,

    you have a gas supply problem and need to call your gas supplier.

    have an oil boiler check there’s enough oil in the tank by reading the gauge.

    Pilot light 

    Is the pilot light igniting?

    the pilot light has gone out you may be able to

    relight it by following the manufacturer’s instructions.

    These are often printed on the boiler door, near to the pilot light,

    the front panel or in your boiler instruction booklet.

    You’ll need to:

    Check whether the gas stopcock is open or not. it’s not, turning it on

    will solve the problem by restoring gas supply.

    is already open and there’s no gas coming through the stopcock

    then you have a gas supply problem

    and will need to call in a gas safe professional to complete the repair.

    your boiler model doesn’t have a pilot light,

    press the de-blocking button. if that doesn’t work,

    check the central heating pressure

    is set to the manufacturer’s instructions (generally one bar).

    that also doesn’t work (and the central heating pressure is correct),

    you either have a gas supply problem

    (contact your gas supplier) or you’ll need to get an approved gas safe professinal in for a repair.

    Remember, you should never attempt to

    dismantle your boiler or alter it in any way.

    If you can’t relight the pilot light then

    you’ll have to call out an approved gas safe engineer.

    Central heating thermostat and boiler levels

    central heating programmer in the ‘on’ position?

    Try increasing the level of your boiler or

    central heating thermostat.

    The boiler will only work when the

    thermostat is set higher than the room temperature.

    Central heating timer

    Check that the timer on your central heating controls

    works and is set correctly. If it won’t switch on you

    may have flat batteries or a problem with the power source.

    Central heating pressure

    Is the central heating pressure correct?

    Check that it’s set to the manufacturer’s instructions (generally one bar). If it is, you

    either has a gas supply problem and will

    need to contact your gas supplier or a

    Gas Safe Register professional.

    Condensate pipe is Another common cause of boiler failure

    A condensate pipe carries condensation from your boiler to your outside drain.

    During extremely cold weather the condensation in this pipe may freeze and cause a

    blockage causing the condensate to ‘back up’ into the

    boiler and cause a shutdown.

    Signs that the condensate pipe may have frozen include your boiler’s display showing a ‘

    fault code’ or warning light as well as

    gurgling or bubbling sounds coming from the boiler or the condensate pipe.

     you suspect this is the problem,

    then you need to unblock or thaw out the frozen pipe.

    Condensing boilers with the discharge pipe going to the outside drain are very

    common problems that cause boiler failure.

    you have tried to solve the boiler failure problem yourself
