It looks like it's coming from some kind of metal push pin

Hi, my names Matt i own EM-Gas & Heating,

check section 12.

you can buy a servicing kit which will include a diaphram washer, which will have split which is why it is leaking

if its stuck in, grab it with some plyers, and get some grease and pull it in and out it might free it up

​ That's great and I reckon that's exactly what's wrong, can I do it myself or does a gas safe eng need to do it?

The info mentions about draining the primary circuit? :P

​Is it safe to remove the micro switch? Or do I need to isolate the power

​Isolate all mains when working as electric and water tend not to mix well.

Yeah better safe than sorry

Argh! stupid thing tried pulling the pin out and because there was hardly anything to grab hold of its pushed it in and it's not coming out now!
It's not leaking anymore though.
What does it do when it's pushed in?

Turn off the power and cold water feed, remove the screw and move the switch out of the way to expose the pin, undo the brass nut which the pin sticks out of, and you will find a small rubber washer around the base of the pin, you need to replace it, you can get a kit which usually includes a diaphragm, a washer, and a new brass nut with a larger metal washer, you probably won't need to replace the diaphragm, just the small washer and the nut/metal washer

​ The cold water feed is that the 2 black valves at the bottom of the boiler that turn 90 degrees?
If I undo the brass nut around the pin will water come out?

No, they sound like the central heating valves, if you haven't got an isolator valve you may need to turn off the main stopcock into the house. Once the water feed is off, turn on the hot tap to let out any water in the pipes, and you only get a dribble when you remove the nut, a possible temporary fix is to remove the small washer. dry it off, smear it with silicon grease, and reassemble, but it is better to replace it, I have a baxi 105 and I have had to do this every couple of years

​It'll have to be the mains stop tap I use then.

I'll have a mess tomorrow as i've got to be up at 5am for work, so i'm off to bed now.

Thanks for all the advice & help I really appreciate it

its not a combi its a system boiler, its not for hot water, its central heating

there is only 2 pipes going to this boiler, flow and return, turn them both off underneath and get some bog roll and catch the water tht comes out when you undo the front

Yes thats right - It's a system boiler.

Cheers will have a bash when i get home from work tonight.

Just another quick question, roughly how far should this pin be sticking out as i'm assuming it must be over 5mm for it to activate the micro switch?

Original Poster

Just a quick update. Boiler all sorted, it was just a matter of taking the brass nut out cleaning it up where the pin was located and putting some silicon grease on. No more leaking and central heating and hot water restored

Thanks again mbordacs and mikey_d
