Too true Maxie, too true.

try these guys , suppliers to the trade , but you can walk in , loads o

branches ,

can supply anything , heating related

I only discovered CET yesterday ... sorry if the fingers were quicker than the brain - just trying to be helpful.

Well, they are the biggest CH merchants ( by a long way) in the UK

Fairynuff, nothing personal!

I'm not expecting to 'see' anything. Just passing on a tip to those who find it difficult to see such things through advancing years.

But if checking voltages, etc, it helps to see where you're probing?

Judging by their website, they must be the same company or group as

(I sometimes use their local branch). Out of interest, what's the story, do you know? Plumbcenter do all the CH stuff as well.

Partscentre do indeed have it on their website... for =A3200 :-( I'll call CET in the morning and see what they say. Thanks for all the advice guys.

Mike.

I was more thinking about a visual inspection to look for damaged components. However ... trying to fault find with the pcb in place, attached to a loom with the boiler up and running, (this particular pcb is inside a plastic case and the display / controls pcb is attached to it), really isn't something which I would like to attempt. You can't really test it any other way without a test rig

[raden]

I think the Wolsley group bought them out, more I don't really know

Just email me with your phone number and I'll give you a ring if I manage to sort it out in the next day or so

Any particular fault in common?

I've just been out to look at an ISAR whose PCB is blowing the fuse in the mains FCU. Checked that it's not the inline filter or the switch: I'm seeing about 3 ohms across L-N on the PCB/module connections with a normal DMM (i.e. not a megger or anything stupid).

Have you seen this fault Geoff?

I've not seen an Isar PCB, but in this case, assuming it has low voltage circuitry supplied by a conventional linear or switching power supply, would disconnect it from the boiler and do the usual checks on the primary side of that (i.e. check bridge rectifiers, chopping transistors if the supply is a switching type, etc.) 3 ohms is the sort of reading you'd get when a semiconductor component has decided to let the magic smoke out.

If the pump is run from the boiler (i.e. it has pump overrun), check it's not a failed pump.

[John Stumbles]

checked with all other cables disconnected from pcb/control module and it's still 3ohms. haven't opened up inside as there's a 'warranty void' sticker over one of the screws and although the machine's out of warranty soga still applies and I don't want to mess with it.

I mentioned earlier in the thread that for some reason I have a problem with (simulating) flame detection, I don't know why. Without being able to do this, I can't test the pcb other than it gets through part of the sequence. I intend to have another go this week. If I have any success, I'll report back. They do seem to be coming through thick and fast now
