Our boiler has packed up this morning, and as we've only been in the
house 6 months I've got nothing to give me a chance of diagnosing the
problem. It didn't help that I had to come to work, so I've not had time
to investigate further but I can't find a copy of the manual online.

The two green LED's on the panel are flashing, and the boiler is humming
like the fan is trying to start, but other than that nothing is
happening. I've tried powering off/on, but the fault stays.

Does anyone have a manual for this boiler they could let me have a copy
of by any chance, or some advice on this problem?

Any help would be most appreciated.

Thanks John.

I now know that the flashing LED's mean it has a 'Software Sequence Error'.

Now does that mean I've got a buggered PCB, or is it likely to be
something else?

Ignore that - the fault is a 'Lighting Squence - Fan/APS' fault. I got my
flashing LED's wrong :)

What on earth does that error mean?

Sounds like the fan is not spinning up, or the air pressure switch is
not detecting it (obviously the control board can't tell the difference
between a knackered fan and the sensor).

These are not particulalry difficult boilers to fault find being about the
same level as a Pott. Profile.

...the boiler is humming like the fan is trying to start ...
Have you measured the supply to the fan?
Have you traced through the wiring diagram?

Sounds like your fan is ...

how should I say it ?

... shagged

prolly the bearing collapsed and the shaft rattling against the
laminations

Is the noise actually coming from the fan ?

it's the second one I've come across today

you might need my website

err ...

The fan is making a noise, the fault is coming up as a fan / APS fault

prolly a gas valve fault then (smiley would follow if I did them)

Well, no - how can it ?

It powers the fan and waits a finite time for the APS to register that
the fan is working, if it doesn't then it flags up an error state

It can't.... which is what I said.

Indeed. We seem to agree ;-)

Ah Yes - obvious really, if only my brain had thought a bit, I'd have
worked out what APS meant!

Homer moment.

I tend to agree.

More an electrical hum from a fan refusing to spin really.

I've had a quick look and the fan isn't spinning - based on the fact the
vanes on the top of the fan are stationary, but I've not metered the
feed to the fan because my test meter picked exactly that moment to die
on me.

Someone is trying to tell me something here I think.

You don't appear to have a Micron fan listed on your website.
