Hi all
Just wondered if anyone could advise? Our Suprima 100 is around 5 years old and I've repaired the PCB a few times (see other thread), and all has been fine for a further 2 years but now she's developed a whistling/resonating sound when the pump's running. I'm guessing its sludge build up in the exchanger but not sure?
Also, I have used those CO sensors and they have all gone dark over 2 months so have brushed out the burners to remove any debris, but again another one has darkened.
So wondering what else I should do?
Any advice would be much appreciated.
