My son's 6 year-old Glowworm 30cxi condensing combi is unwell. He
noticed no dhw, then saw the display flashing all bars and noticed that
the boiler was making "some noise". He power cycled it: no change; power
cycled again: this time no display, no sound, nuffink. No F codes at any
stage.

I've established that there's 240v at the pcb, and that the pcb fuse is
intact.

Could it be anything other than, or as well as, the pcb? I've seen
references to fixed price repairs - who offers these? BG? Glowworm?

I'm happy enough to swap a pcb, but I gather they're not exactly cheap,
so I'm hesitant to do so if another component is going to make it let
its smoke out.

Any advice, please?

Thanks for the comments to date.

Son has decided to bite the bullet and pay Glow Worm. They offered
three options:

Fixed price repair - £260

One year service agreement, including initial repair but with £99 excess
on any subsequent repairs - £200

As above, but no excess - £300

Careful questioning as to why anyone would go for the £260 option
instead of the £200 revealed that they don't offer the £200 one for
boilers over a certain age. Hmmm.

So they're coming tomorrow. I'll report the outcome.

They came, as agreed, on time (07.30), and replaced both the main and
the display pcbs. I couldn't quite follow why the display board needed
replacement. They also replaced the inner door seal and main burner
seal, and ran the usual basic checks, but not the gas consumption.

No adverse comments about the (non-Corgi) installation apart from
disliking the use of about a yard of 22mm copper for the first part of
the condensate drain.

We'll see how things go from here, but I'm beginning to conclude, from a
sample of two, that modern boilers are one of the few cases where some
sort of maintenance agreement is a Good Thing.

Two other points from the repairman: maximum length of outside
condensate drain in 21.5mm is now reduced to 1m; and when asked which
make of boiler he'd buy for himself, he unhesitatingly said Vaillant,
because W-B standards had dropped recently.

Yup, I'd go along with that

That's what Mr Gasman also said to me in his latest visit for an annual
service. He used to be very pro-WB.

Being an electronic engineer, I wasn't about to pay that without looking at it
first, so this is what I found:

Symptom - Dead, no display and a faint ticking sound when the power is turned
on or takes a long time to power up from cold. Fuse F100 is intact.

The switch mode power supply (adjacent to the fuse) is not starting up. This
is caused by a faulty electrolytic capacitor C805 situated at the bottom of
the PCB near to the fuse. This is a 47uF @ 50v. Be sure to obtain a 105 degree
type, not a cheaper 85 degree as this will provide a much longer service life.

A suitable type is available from RS components (www.rswww.com) part number
520-1567 priced £1.50 for a pack of 5!

It may also be worth replacing C813 100uf @ 25v on the power supply secondary
at the same time. This is situated at the bottom of the PCB to the left of the
small transformer.

A suitable type is 519-4150 from RS priced at £1.00 per pack of 5.

Remember to isolate the boiler mains supply before touching the PCB as it is
very, very live!!!

Hopefully this will save people some money :0)

When did Kevin write that?

I know it's on your web interface, I checked once. Those of us with
proper newsreaders seem to see it better.

Mr Haywood may well know about electronics, but he needs to learn the
difference between a spamming web gateway and Usenet.

snip good-sounding advice

Setting aside the comments about the route of Mr H's reply, I'm grateful
for something else to go onto the "it might come in handy" shelf.

The boiler in question has performed faultlessly since then, but I'll be
well prepared if it fails again. If I can remember which shelf I put
the information on.

So, thank you, Mr Haywood.
