As per title, there's a slight drip of water from the LHS rear of the burner tray. Only spotted it after the boiler started showing symptoms of either a faulty sensing electrode or blocked condensate trap (5 ignition cycles then lockout). Unplugging the trap sensor cured it, but then I noticed water on top of the trap, which was shorting out the sensors.
I don't know if it's condensate or system water (can you taste the difference? And do I really want to be ingesting X100??). This doesn't seem to be a common place for these to leak from. I can't see where the leak originates from.
This boiler is really on it's last legs and has a history of kettling so I'm fearing a rotted/leaking heat x, unless anyone has any other ideas???

Cheers.

Probably condensate!

But you need an RGI as you should not be opening the combustion area.

It was dry again this morning after being switched off all night, but was dripping again after about 2 mins of use so yes, it's probably condensate leaking from the burner tray/heat x joint. I'm not throwing any more money and time at a dying boiler so the plumber's coming later on to give it the last rights.........
Oh well, it nearly made it through the winter!
 
Its the last 'rites' !

Probably a simple fault to fix.

Better to get a boiler engineer than a plumber!

There was an issue with the Promax where a seal caused water to drip onto the condensate trap earthing the flame detection signal.

It's been ages since I last did one and my grey matter won't jog as to where it was from but they weren't too hard to do.

It also needs a new combustion box door, burner, manifold seal and it kettles like crazy if you run it at 80 degrees. Beyond economical repair......

That's exactly the problem. Looking at the parts diagram it's probably the seal that sits between the burner tray and the heat x.

Sounds like the words of a destitute installer who wants to fit a new boiler.

Otherwise, just a list of items to dealt with on an average repair visit.

Yes the seal was prone to leaking on the earlier versions of the Promax.

I wouldn't say so but it's your appliance

He hasn't suggested a new boiler. That's my call.

This is our 5th winter in this house and this boiler has been nothing but trouble every single one of them. It's an old boiler (2003) which was badly fitted and commisioned and is now suffering for it. I'm simply not prepared to throw any more time and money after a lost cause.
If you reckon the boiler's still good, you're welcome to come and collect it FOC! :)

I dont rate them as a very good boiler
but they are still repairable.

i do collect less common old boilers, partly for pathology and partly as a reference for spare parts and to give advice to people.

You dont list your location. Where are you?
