|Potterton piece of sh1t!
||[Jun. 1st, 2004|10:18 am]
Please pardon my French, but don't ever buy a Potterton boiler for your
home. I have a Potterton Suprima 70L and it has been nearly as useless
as a bag of crap. This explains why you see the name mentioned so often
on plumbing DIY forums and newsgroups. Intermittent faults are what you
mostly hear of. Well, I've had loads of those and also some of a more
permanent nature. I called a guy out for a service and a fault find
back in November/December last year. The problem was intermittent
lockout. Occasionally the boiler would shut down and refuse to fire up
again until the user (that's me) presses the manual reset button. This
resets the overheat thermostat and restores normal operation. Of course
when this happens in the dead of winter while you're sleeping you may
find you can see your breath when you wake up. This was happening often
enough for it to be sufficiently annoying as to warrant a service.
Anyhow, the engineer replaced the printed circuit board (pcb), which
I've discovered is a common remedy for such faults. In fact these pcb's
are so shoddy that I've read threads recommending that you remove the
board and look at the contacts under a microscope for loose solder
joints and then using your soldering iron, which I know you have in
your utility cupboard, to reflow the solder and restore the contact.
Here is an example of your typical thread:
http://www.diynot.com/forums/viewtopic.php?t=3857 . That new board was
supposed to be an improvement over the original release. Well that
board permanently failed THE SAME DAY! So I got the company to send out
another engineer to replace the board again. The new new board
eventually began to have intermittent faults shortly after 30 days, the
event horizon for having to pay again.|
I've been fiddling with it myself ever since then. When the new new
board finally failed permanently about three weeks ago I swapped it
with the original board still in my possession. That worked fine for a
while but then got dicky a few days ago so I took the board out and
cleaned the contacts with cotton buds and surgical spirit. That gave
good results until yesterday when the boiler locked out and looked like
permanent failure. So I disconnected the overheat thermostat and
powered it back up to see if the thermostat was actually the problem.
The boiler wanted to light. I could see it trying but just before it
was meant to light it would lock out again, probably detecting that the
overheat thermostat was disconnected. Then I reconnected the thermostat
and powered up. Everything seemed fine once again. I went to bed
because it was 12:30 am. This morning it was acting up again. So
basically I'm going to replace the piece of sh1t with a reliable system
from Vaillant based on their reputation. I wanted to have a combination
boiler anyway so now's my chance. I have no idea how long this will
take or how much it will cost so I will be making some calls today. In
the meantime I will have to try to maintain the boiler so that we can
take showers. Fortunately there are some sites that sell spare parts
directly to the public. I may pick up a new thermostat, thermister and
air pressure switch for a few quid each and then see if I can get the
new new board working, which to be fair might only be complaining about
one of the other components not working properly. I'll try the
soldering thing, something I'm comfortable with but I don't have a
soldering iron at the moment. If it seems to be working then I'll sell
the whole system on eBay. I've noticed one or two others selling their Pottertons
that way as well as some sellers selling nothing but the boards. That
ought to tell you something.
Potterton sounds like a more suitable name for a garden centre to me.
It sounds like the surname of a hack murder-mystery author.

Not surprising really. The manufacturers are probably better at both gardening and novel writing.
I wrote "microscope" but what I meant was "magnifying glass". I would be surprised if it were possible to look at a circuit board under a microscope unless the circuit board happened to be translucent. And certainly if you had to look under a microscope to find flaws you would be working with a very small soldering iron indeed!
