Afternoon folks.
I am back once again with a Puma problem!
I won't be carrying out any work as my landlord has an excellent gas engineer, but I like to find out what the cause(s) of the problems are with my boiler so that I can ensure the engineer addresses the correct areas. (My landlord often will instruct tradespersons to employ a safe, but temporary workaround instead of a long-term fix if a long-term fix would be expensive (such as major part replacement).
So the issue is this:
Around three months ago the boiler was losing system pressure every evening (going below 0.5 bar and illuminating the Low System Pressure light). I had to recharge every morning. After two weeks of this, the pressure stabilised and the issue stopped happening.
About 8 weeks ago the boiler was running as normal with CH and HW all OK, until I heard very loud noises (imagine the sound of a large, seized spring being stretched) and a LOT of deep gurgling sounds coming from the boiler. (Sometimes I worry as it sounds like the pressure vessel is going to explode)! I have heard these a few times since then, although two days ago when it happened the auto air vent discharged and the burner went out. I attempted to relight the boiler but when I release the gas control knob the pilot extinguishes immediately. I believe that the thermocouple needs to be replaced as I had this problem once in the past and the 'workaround' used to remedy it was to unscrew the thermocouple and re-route it through the front of the chamber push it into closer contact with the pilot flame.
I think the thermocouple has reached the end of its life and needs replacing. Would you agree and if so, do you thnk that this will resolve the problem?
Also, since the issue two days ago the DHW LED remains lit for upto 60 secs+ after turning off the HW tap. The spring and piston in the DHW flow switch appears to be sticking. (I have only noticed this since the boiler stopped working, and therefore I have only been able to test it with the boiler off).
I would prefer a new boiler but I don't think I am going to get one.
All thoughts and advice will be greatly appreciated.
Kind regards,
Gaz
