The numerical display on my ATAG E32C combi boiler is failing; half the segments don't work any more. This display is on the PCB so I'm guessing the whole PCB has to be replaced. It's about 10 years old.

I can buy a repalcement board for about £200.

Am I right in thinking that replacing the board would not be simply a case swapping them over, but that the new board will need to be set up before the boiler can be used?

It's very hard to find anyone near Cambridge to work on an ATAG boiler. So hard, in fact, that I am considering replacing the boiler and gettign something more standard.

Thanks for any guidance.

Im not sure the boards need €˜setting up. I replaced a boiler PCB some
years back and it was just a simple swap. A friend in the trade sourced one
for me. I then looked over the duff one, found the fault, and replaced the
components. I kept it as a spare for years.

Sometimes small LCDs just need the edges pressing down a bit. A card spacer can do that.

Ebay is often cheap for spare parts. If it's not a combi, you can even get whole boilers for parts. Atag isn't the most common though.

I would have thought that any setting up needed, if any at all, would
be something like coding plugs or links rather than any electronic
coding or potentiometers, so just check against the existing board and
copy that.

If you can post a picture of the display, that would help us ID it.

Assuming it's this board:
https://www.ebay.co.uk/itm/ATAG-S473...-/323535065962
it doesn't show any display. Is it on a separate plugin module? Is the
module plugged in directly or via a cable? What kind of display is it?
(Dot matrix, 7 segment with custom symbols, graphical?) Is it a
calculator-type LCD (with backlight) or do the segments light up (LED, OLED
or VFD)?

The classic dot matrix 16x2 character displays look like this:
https://www.adafruit.com/product/399
but it sounds more like it's a custom segmented display, which would make it
more difficult to find a match.

Ah, scratch that. The above picture shows a bank of four 7 segment LEDs
next to the buttons - they're so overexposed that I missed them first time
around. Those would be relatively straightforward to replace with a
soldering iron.

Next question, can you describe a pattern of which segments are failed? For
example, it might be the top segment on each digit. Such a pattern points
to the driver chip. That appears to be the chip on the picture to the left
of where it's printed 'OK' upside down at the bottom of this image:
https://i.ebayimg.com/images/g/JygAA...Ui/s-l1600.jpg
Can you read what's written on that chip?

Thank you all for your help and suggestions. A new board is £480 I now discover!

because I can't read the existing display I'm not able to note down what everythign is set for at the moment. IN addition, I now find that the boiler has anther fault (overheat tripping and, the latest: triping the RCD in the ring main).

So I've decided it's now time to replace the whole boiler!

I don't recall the make- it was in our previous house. However, I don't
think it was an ATAG.

That aside, the boilers are intended to be repaired by simply swapping
parts. If thing get more complicated, the 'average' service type is
often stumped and needs to call in someone else. Therefore, I doubt
boards need more than swapping.

could be due to any part of the boiler, pump or valves. Best way to test them is to temporarily disconnect each & do a hi-pot insulation test from L+N to case. If you lack the equipment, a multimeter usually picks up the problem.


So I've decided it's now time to replace the whole boiler!

As they say, you can repent at your leisure I would not renew a boiler until I at least knew it was faulty.

It does this only on Domestic Hot Water (not the CH). I suspect it means the DHW heat exchanger is clogged. On DHW this boiler runs a little circular loop of water between the gas heatex and the domestic water heatex. When CH is running it just goes through the gas heatex.

All these things that have been going wrong cost money (or time or both) to fix and when you add them up it makes a new boiler a viabale alternative.

My dad used to employ a man from time t otime to fix loose slates. He just walked about on the roof with no safety gear. My dad pointed out how dangerous this was. "Nah, I've been doing this all my life and I've never fallen off" he said. A short time afterwards he fell off a roof.

True. I had a hose split on my Viessmann which soaked the gas valve. Which
then blew a fuse on the PCB. And the fuse was one of those round PCB
types, soldered in. Not many plumbers would carry bits to sort that. And a
new PCB costs hundreds. The fuse, about 20p.
