Hi

My boiler, a Myson Apollo Fanfare 15/30 has stopped working. i found
that the boiler had stopped and tripped the MCB. If i try to reset the
MCB it immediately trips again..

I have stripped the boiler down and a quick visual inspection reveals
no obvious problem. I checked the fan which i have had problems with
in the past and it seems ok. Are there any common faults i should be
aware of and be looking for with this boiler?

Any help would be greatly appreciated.

Regards,

Neil

Either water damage (inspected, you say) or the pump are the most likely
contenders

If you are competent to do so, have you run the fan directly off the
mains?

The boiler goes through an ignition sequence (demand, fan on, APS
switches over, pilot and spark, flame sensed main valve on).
You might be wise to determine at what point the boiler crashes if you
need further advice.

Hi thanks for reply. There are no signs of water damage. Haven't had
much time to investigate the problem yet What I checked so far is the
MCB trips instantly mains is applied. I've disconnected the fan which
has no effect - the MCB trips straight away ( I know the vacuum switch
would hold everything off but just wanted to check it wasn't the fan
causing the problem). It also does this whatever the boiler stat is
set to. (high, low or off)

My next step is to check out both pumps, but with the fault occurring
instantly i'm concerned that it's some part of the control circuitry
as i assume this is powered up all the time and should sense when
ignition is required.

Thanks again,
Neil

IME when you have a trip/blow electric problem with the heating the pump
is guilty until proven innocent.

No, the sequence board is only powered up when called upon to provide
heat

Go for the pumps first

Thanks very much to the both of you! It was indeed the pump in the
boiler circuit. I broke the circuits down and tested each individually
until i found the faulty component. The pump has no physical signs of
damage although the unit smells as if the insulation on the motor
windings has been rather hot and broken down!

Anyway all is well again now that i've replaced the pump. Once again
thanks for your help.

Regards,
Neil

It's because homeownershub users ONLY see the original decade old
question and non of the replies.

Because of that bloody stupid interface at home owners club thingy that
seems incapable of sorting messages by year never mind anything more
sensible. That shower who wrote this interface really need to get themselves
clued up.

They are clued up. The aim of the home owners hub is not to provide a
service to the great unwashed on the internet but to provide a service

You dont know that, or that they arent just using advertisers to cover some
of their costs.

It's on the screen, but apparently they don't see it.
