Hi all

Hope this is an appropriate group to ask this question.

I have a newish house (just under 4 years old) and the heating system is
powered by a Potterton Suprima 60 wall mounted boiler.

All has been well until a few weeks ago we started getting problems with the
boiler locking out intermittently for no apparent reason.

The pump continued to run, but there is a little red LED on the control
panel which flashes.

On pressing the reset button, the boiler fires up, and away it goes again.
It could then be fine for several days, then the same thing happens.

I have been ringing around to find an engineer to take a look at it, but
then by coincidence, we had a note put through our door from a neighbour,
who was having exactly the same problem, and on consulting his neighbour,
found he also had the same problem.

He called an engineer who said that this was a known fault with this boiler
and that later models had been fitted with a modified electronic control
unit to cure the problem. However, to fit the modified unit to his boiler
would cost £250.00!!

Potterton deny that there is a problem with this boiler.

Has anyone else encountered this problem?

Thanks in advance

Paul

Ah... just spotted it - sorry folks!

Seems I am not alone......... :-(

It's a simple DIY job


Potterton deny that there is a problem with this boiler.

As they do, every time


Has anyone else encountered this problem?

From the other side, yes, many times a day

Thanks for this Geoff - I will check the part number - looking at the boiler
manual it seems fairly straightforward to change the PCB, and as far as I
can make out, it doesn't involve disturbing any gas carrying parts, so does
that mean I can do it legally?

Also, our neighbour distributed a circular letter to all the neighbouring
houses (all built around the same time) and within 12 hours, a further 10
people had rung him to say they had exactly the same problem.........!

Any discounts for bulk orders...?? ;-)

Already under way Tony........ copies of my letter to Potterton have been
circulated to neighbours, as will print outs of these replies as long as
nobody objects......... ;-)

Unless 1000's of people actually get together and get the media
interested, I think it's just head banging against a brick wall.
POtterton just don't seem to give a ****.

It's just a matter of removing power to the boiler, pulling the panel
down, removing the connectors, undoing 4 screws, replacement being the
reverse of removal.

To work on your boiler, you have to be "competent"

.... the definition of which is left to the reader

They are shifting so fast at the moment, I'm not sure I can handle 12 in
parallel, it might have to be a couple at the time

.... oh and potterton's current "reason" for failure of suprima pcbs is
that they are sited too close to the heat exchanger. Move over at the
comedy club, there's a new act in town !

That's interesting....

I have a Suprima 50 and over the last 3 years since install, its had a new solenoid about a year ago and a new HT lead (3 weeks ago). Now its developed a problem where gas ignites and then after 3-4 seconds extinguishes. The three re-tries happen and then we enter lockout.

We thought we'd take the tried and trusted route of total power off to the boiler and leave for 5 minutes. 7 out of 10 times the fault goes away for a few hours but then returns. So... when time passes with no activity... it get better... is there a logical conclusion? Duff capacitor? Heat failure?

Either way Geoff, expect a call from me soon for a new PCB!

By the way, what's the difference between these parts on your website Geoff:

Potterton - Suprima - 407750 - 114954
Potterton - Suprima - 510216 - 114954

My user guide refers to 114954 PCB Issue 04..?

Cheers

Apparently there are 13 issues of the PCB and now they have introduced a
complete redesign.

Have a look at the spark gap - on my suprima this is problematic if too big,
and can produce these symptoms. The reason is that the pcb flame sensor uses
the gap, as well as for ignition sparks, and if it the gap is too wide the
boiler decides there is no flame and shuts down. I got best results at just
under the specified gap - cant remember what this is without digging out the
manual, but could check if you don't have it to hand.
