Baxi solo 3 40 pf boiler falut


Postby robsoo » Thu Nov 20, 2008 7:01 pm

Can anyone help me. I have just had the PCB replaced on my boiler. it worked fine for all of one day!!! then started misfiring. I have uploaded 2 30 second clips on to youtube showing whats happening

As you can see when the heating is on, the boiler lights up but then clicks off, tries again then keeps tripping off. Even when i switch the heating off the boiler continues to try to light for about 10 minutes!!

Can anyone help me, my house is freezing as rads are only getting luke warm. Plumber who fitted PCB has advised my it may be my timer but from looking at other related posts i think he's talking sh!te!!!

Please help....oh yeah i am a layman so please try to bear this in mind if you reply

Thanks again everyone!!!!

not really apart from the clidking of it trying to switch on and then tripping off. this can be heard on youtube vids. thats all the noise it makes though.
PCB is brand new though only fitted a week ago.

When the burner light neaon comes on - does the electrode stop sparking ?

If it continues to spark then the electrode or HT lead is not sensing the flame and therfore will not allow the burner to remain on.
