Worcester boiler flame detection light staying on for a few minutes

[sammick80]

Hi, any advise greatly appreciated. We have a Worcester 24CDi boiler. The flame detection light goes on for 1-2 minutes then goes off for a few minutes then on again for 1-2 minutes and so on. The radiator light stays on and the radiators remain hot. Is this normal or is there a fault. Today the temperature was set at 20 degrees and all the while it was going from 17-20 degrees the flame detection light kept coming on and going off. We have had constantly hot radiators. Am I worrying over nothing? Is this normal? If not what is the problem? Many thanks in advance

if the boiler is cycling on and off the whole time that is not right

 

[sammick80]

do you have any idea what could be wrong?

 

[gasmarc]

it could be a pcb problem ,flame electrode,etc difficult to say without seeing

could be ntc,dodgy flame rectification,get it checked out by a gsr engineer,could be few other things,
more than likely stop

hi,
If your boiler is switched off and on after 1-2 minutes automatically than there is some problem exist in that you replace your boiler or repair it.

Thanks!
