Combi Gas boiler

[Last plumber]

F14 is high temp on heating flow.
Could be a number of things. You need someone to test it really.
I 'm not going to guess and get it wrong, sorry.

No just DHW

With the heating off run the bath tap and leave it running while you go to the boiler. is --- firing? if yes, put your hand on the pipes underneath. One of them will be hot. That pipe will be the heating flow. If it is you have either a blocked plate heat exchanger or diverter valve problem. If the boiler is not firing then it might be the dhw thermistor.............but it could be something else.

Remember pete I said the thermistor was scaled up or faulty or the BULB needs changing

 

[Pete999]

Update. Gas eng been changed thermister, pump, stumped eventually called Glowworm help line, heat exchanger blocked. £450 for replacement and £600 for a system flush, so gettin on for a grand for repairs to a 10 year old boiler, going for new boiler. I had the exchanger changed 2 years ago, sod paying that money every couple of years

The thermistor clips on to the pipework can't see how it could be scaled up, nackered maybe, thanks for the input anyway, oh by the way all the LAMPS were OK

 

[solarsavings]

Well thanks for that

You didn't think my imput was of much help but it seems I was was right and the guy you had out was a dick.
A grand to clean the plate I will do it for half that...................or maybe a lot less.

You can't clean these plates it's replace or go without, what makes you think I didn't think much of your input/ although my reply may have seemed as a sarky reply it wasn't meant that way

 

[solarsavings]

Yes you can Pete. I do lots of them.
Sorry if I misread your reply.

Yes that's the jobby, well I stand corrected will go to the naughty step for the rest of the evening, just a question for you, how long will that exchanger last until it's next clean, I realise that depends on lots of variables, just a ball park idea,
