Is it calling for heat.....ie the heating is on or a tap is running?

focusv8

You got the gas turned on?
or
Pilot blocked,
or ignitor failed
or gas valve failed
or main burner flame detection failed.
or main PCB failed

Good news though the fans o.k.

.

rapidcossie

blocked pilot is my guess.

can you hear it sparking?

rapidcossie

sorry I just re read that.

the solenoid for main gas is fucked on the gas valve.

Jon(M600BHP)

Dont think you can just buy the solenoid either

rapidcossie

nah you cant I dont think.

alrite mate just spoke to my dad and he said either pumps not running or you got a faulty gas valve or there mite not be enough pressure in the system if its pressurised

rapidcossie

This boiler doesnt have a flow switch so the pump running or not wont effect start up.

Not sure if this boiler is sutiable for sealed systems either so the pressure this is out the window too.

If fan and pilot light are on but no main burner ist defo going thru igntion seq so is defo seeing demand.

Last thing on igntion is power to main solenoid and lights main burner.

An easy check is to remove solenoid and check resistance with multimeter.

Never overlook the obvious, do you have gas? No offence, but been to many jobs to find that!

rapidcossie

He states that the pilot neon lights so he must have gas foxy

focusv8

Unless it's got pilot flame proving it could be no gas.
Pilot neon just proves the burner sequence is trying the pilot.

.

foxy06

Fairplay mate, never seen that when i read! But neon lit only proves electric sequence works.

If no that, agree with the solenoid problem, next port of call!

are you running the heating from a thermostat/programmer? or timeclock which is on the boiler, try setting to override? as maybe kids have played about with it??

thanks for all the replies, as stated thers deff gas getting to it as you can see the flame from the pilot, ive put a new programmer on and made no diff so took it back to b&q , when i ask for heating nothing comes on ? when i ask for water everything comes on but the ..boiler on .. what does that tell anyone, and whats the best way to check the pumps runing, as it does sound very quiet but when i put my head to it you can here it

thanks

no sparking as i can see the pilot flame is on

morto

ok some thing new left it on hot water and burner came on for around 10 secs then switched off again, so what would cause that?

focusv8

Flame detection probe faulty/dirty.

.

the original

so how do I service a baxi solo 3pfl?
are there filters inside that need to be cleaned or something?
will I see when I take the front off?
or is it not d.i.y?

rapidcossie

NOT DIY!

rapidcossie

if the flame dection wasnt working it would stil be sparking

Hi Morto,
just seen your comment "when i ask for heating nothing comes on ? when i ask for water everything comes on but the ..boiler on.. ............."

Regardless of what may be wrong with the boiler, this tells me you have an issue with the mixer valve.
I have a Drayton mid-position valve in my system, and when it got a little furred-up recently (hard water problem), it wouldn't go fully to the heating-only setting, and therefore didn't switch on the power to the boiler.
If you have such a valve, you can check if this is the problem by separating the electical body from the brasswork (simple operation). Then set your system to ask for heat-only.
If the boiler fires up, you will know that the valve is suffering from reduced movement, and needs replacing....... although I extracted some extended life from mine by giving it a good wiggle with an appropriate spanner.
Note though, that even when it's working fine there is only a very small arc of movement, so don't overdo the wiggling.

michaelcarts

Hi again Morto......
By the way..... did you ever confirm what the boiler problem was ?
