baxi bahama 100 ignites then cuts out

[hodgy]

HI,having a problem with a baxi bahama 100 combi boiler,when switching the heating on or turning on the hot water tap the boiler fires for about ten seconds then cuts out,any ideas please as we have no hw or ch.

Could be split aps pipes or faulty aps its self. Could be fan venturi partially blocked.

When was it last serviced?

Thanks for the reply i don't think its been serviced for a while,i will see about getting it serviced asap.thanks

or failing to prove ignition? Needs an expert visit.

Low gas may need setting up...

Got my problem sorted,turned out to be central heating flow switch,fixed at the cost of £23.Bargain.

Perhaps, I was looking too deep and missing the obvious?

mmm

can the ch flow switch on this prove then fail, I thought the beggars just failed

??

no wot happens is magnetite gets attracted to the magnet in the flow switch causing it to fail but it can quite easily get circulated around by the pump causing intermittent faults

so to cure this apart from fitting flowswitches every few months would a magna clean cure this

i personally always recommend them on this boiler as magnetite is a real problem for the flow switches
