What is the brown wire in terminal 3 connected to??.

Live at the programmer.

Problem has started again. And the other end of the brown at terminal 3 at the programmer side looked like this... Subsequently I've stripped some fresh copper and the problem is still there. I've checked at terminal 3 and that side was clean copper

Not a very clear photo, but....

That brown would have me wondering why it was like that, what had caused it. Usually, copper becoming discoloured like that, is due to chemical attack, or overloaded. If overloaded, the plastic insulation will usually evidence that, but I'm not seeing that.

I refer you to my previous comment about reconnecting/wiring the system from scratch.

Oh, and look up some electrical terminology techniques.

Yours are awful as is the corrosion.

I see no point in fault chasing any further until you clean that mess up tbh.

I don't find your attitude very helpful, it's a public forum. I didn't ask you to comment but you seem to be condescending quite often in your posts on this forum.

You're asking me to rewire the whole thing?? If the wiring has been fine for 25 years why do I need to rewire it?? Everything is connected to where it should be.

You seem to fail to understand the issue. When heating or hot water comes on it doesn't randomly go off, the issue is for it to start. Sometimes it starts perfectly fine other times it doesn't.

Think you need to get a new hobby rather than give people wrong advise.

So do you know what this wire is actually for??

1stly,
Nobody on this forum gives "Advice" nothing is official or guaranteed.
Posters only give "Opinion " it's up to you what you do with it.

Secondly, I'm not the first poster in this thread to get frustrated with your ignorance of the obvious.

Thirdly, you are free to say and do what you want, but some posters have gone to great effort to help you out and you don't seem to be able to execute the opinions as given.

I stand by my opinion from the entire contents of the thread that your wiring is ****e and there is no point going further until you sort it.

Best of luck.

Frustrated?? Like I said you don't need to come on my thread. Get a life and jog on grandpa. Perhaps go on a dating site.

If you think I haven't taken advice, then you need to visit spec savers. It's people like you with your obnoxious, ignorant attitude that let this forum down.

You admit you're not a electrician or a gas engineer so you shouldn't be giving advice particularly to rewire the whole system because you don't like the look of it. You may call it opinion, but people come for advice and advice is given. Perhaps you need to brush up on basic common English terminology before telling others to get electrical terminology correct yet you're a diy'er yourself. Talk about hypocrisy.

From Terminal 3 on the pcb to the L on the programmer backplate.

Sorry you feel so angry about what are genuine opinions meant to help.

Hope you find the solution.

Opinions from others I received, from you it was obnoxious behavior. Previously you knew I tested the wires yet you told me to do it again, I let you off last time but you pushed your luck this time. Get yourself on a dating site buddy.

From Terminal 3 on the pcb to the L on the programmer backplate.

I thought the programmer L would be fed directly from the wiring centre so confusing (to me, anyway) why its fed from the PCB terminal 3.

To make it more confusing 2 on the backplate doesn't have a wire

There is bare copper / damaged insulation On the blue wire ,near the bottom cable entry. Needs attention.
Terminal 2 doesn't have or need anything connecting to it on Y plan.

What about terminal 3 on the boiler, is the brown wire not doing anything?

It can't be a permanent live from the programmer to the PCB ,maybe Noddy is mistaken.

I don't understand?

Could the issue be due to the cylinder stat? But then the test the other day worked fine.

Rads were changed a few months ago and some pipes were adjusted, wondering if any wires close to the pipes might be affected due to the heat of the pipes.
