Pilot light going out?

[diamondgas]

What do u think diamond

Visual first on the pilot will tell you a lot. Also visual on lighting up and running. watch see what is happening to the pilot flame! A soft pilot flame can be pulled off the t/c by the burner once alight! ... Nice blue flame enveloping the t/cupl! If you're taking the burner out might as well replace the t/c and clean the pilot injector TBH! Can't be much mcnvens.? Stick to the simple stuff first, watch to see what's going on then decide next course of action! imho

When flame goes out (extinguishing pilot as well) can you hear thermocouple magnet release afterwards?

If you can't hear it then it may be that thermocouple is shutting down during the five minutes of burn, then closing gas valve to main burner.

that points at the pump. Which...... Could be anywhere!!

Top tip, if you look for a pair of pump valves then the pump is usually between them. Hope this helps.

Ok well batter on and see how it goes, always feels like diving into something new when you come across a boiler never worked on, takes you out of your comfort zone when it's not a shiny beautiful combi inside lol...

As I said aswell , I explained the ideal rep about should the pump be faulty wouldnt this cause the burner and pilot to go out due to overheat he said no, this would only cause burner to go out keeping pilot on because it doesn't contain that other stat we mentioned

He said the gas is being cut off somewhere, and on this boiler the only place is the gas valve or tc

Just always keep 3 thermocouples on the van and change um every time you have any doubt, there dead cheap and it rules it out on the 1st visit, then if you get a call back you can be pretty sure its the gv

The best advice I got when I was younger because I couldnt fault find on combi's are

When you come accross a new boiler take the case off and have a look around before you start and make a mental note of what parts you see all boilers work the same just the parts look different and some have extra parts. And the only difference between a combi and heat only is that your pump, 3 port, HW stat is in the airing cupboard not the boiler.

Job done

Removed burner and cleaned renewed thermocouple old one looked a little battered

Kicked boiler on 20 mins later still burning away. Only logical answer I have is that when burner came on it may just of slightly pulled the flame off tc just slightly enough to cut her off after a couple mins.

Thank you team!
