Don't you just love intermittent faults?

[buckley plumb]

the problem i have is when fitting the wiring i keep pushing it off the clip - quite easy with the side panel off though

 

[Dannypipe]

Yeah I took the side panel off. No way I could do it without. I'll get the pics loaded up now.

as mark will tell you if you ever do a diverter remove the pcb - it caught me out covered drop down panel with 2 tea cloths and then wrapped in a plastic bag and taped up and the pcb still got wet and blew - the water tracts down the cables into the pcb.

Well I promised you photo's so here you go!!

That's a mains boiler, the baxi,s have two sensing tubes and three aps wires. A tip if your stuck for room at the side to take panel off, take the fan out.

2 tubes on all variants 24kw has 2 wires 30 has 3 wires be it baxi,potterton or main

There's only one tube Going into the Venturi, where does the other one go?

 

[Dannypipe]

I would have taken the fan out if I'd had to, luckilly with the side panel off it was very straight forward.

Whether the problem is fixed, we shall have to wait and see. Boiler was working when I arrived, and had been ok that day.

I tested the old APS.

The C to NC wasn't working when I blew into it, or it may have been the C to NO wasn't breaking. Anyway it had an issue, but not one that I can see would have affected the boiler, as it was the wrong terminal (if that makes sense!!!!)

basically the honeywell aps gets too hot behind the fan after it was relocated when the boilers became HE the diaphragm in the switch gets overheated and eventually sticks and fails

 

[Dannypipe]

I wish my memory wasn't so bad, but I installed it, checked it. Then had to dash as one of my best mates called. He had put a breaker though a water mains in his house, and then sheared the stopcock.

Luckilly I was only ten minutes away.

The green centre of the APS did look a little heat damaged, and like I say either the NO wasnt breaking or the NC wasn't making I can't remember so it def' had an issue.

Thanks for all the help everyone. Hope this may help someone else who's called to fix a boiler that works perfectly every time you turn up!!!

out the back of the combustion box,the airflow through the aps has to go somewhere but its plugged so just a small amount travels down the tube

If you ever get to go on mastermind, you should choose baxi products as your specialist subject. I'd put money on you.
