I need help with my firebird boiler please.

[katiesprite]

My firebird combi c26-2007 boiler has cut out, the high limit thermostat reset button has activated. When the boiler cools down I press the reset button and the boiler starts imediately and as soon as the boiler warms up it cuts out again. It does not circulate water. The burner lockout is never activated. It doesn't need resetting.

Is the system Pressure gauge reading around 1 bar??
is the Circulating pump running when the boiler fires,
sounds like a job for a Service engineer!!

 

[katiesprite]

hello

yes the boiler is at one bar.

no the circulating pump isn't running.

no the circulating pump isn't running.

That's your problem then.

 

[katiesprite]

what would cause the circulating pump not to work/run?

 

[xr4x4]

Seized pump or an electrical problem.

To check if the pump has seized, with the system off, find the pump, unscrew and remove the silver metal disc with a slot on it, a little water will come out.

Put a flat blade screwdriver inside, find the slot and see if the impeller inside spins freely.

If it does, it's not seized, if it doesn't, see if you can work it, force it to turn, also giving it a few bashes with a hammer sometimes works.

If you can get it turning, replace the disc and fire up the system and see if the pump hums/spins.

my dad has checked the pump and he said that the impeller does spin freely.

it must be an electrical fault. how could this be fixed?

Check voltage @ pump terminals.

 

[katiesprite]

my dad said he hasn't checked the voltage @ pump terminals so he'll do that, thanks.

he's wondering if it could possibly be a problem with the sika flow switch? if so how could it be fixed?

The symptom indicates a lack of actual flow through the boiler.

That could be lack of water or the pump not turning.

Have you checked to see if the pump is actually turning? Opening the screw and seen if the shaft turns?

If not see if there is 230v at the pump connections/

There are two pumps on the combi, he needs to check both of them.

Not if you think you are superior to others no.

my dad only checked the one pump. that was perfectly clear so he took it that the other pump would be too.
