Grüße an einander.
Ich kann nicht so gut deutsch, entschuldigen Sie Bitte den Text in Englisch:
I am in a quite desperate situation with my Vaillant ecoTEC exclusiv 146/4-7 boiler.
Long story short:
Boiler works in emergency mode, producing a terrible amount of CO (out of range of analyzers, ~20.000ppm) and no one is able to find out what is wrong.
Long story:
Cca in February this year I have noticed that the boiler makes some loud noise, like vibrations or shaking (
)
On screen was emergency mode S40/F55, CO sensor is broken. I called a (first) technician.
He replaced the CO sensor but the problem remained. Then he came with a suspicion that it could be a problem with chimney.
The chimney is cca 3m going from boiler directly to the roof, with a coaxial pipeline for exhaust and air inlet.
If the chimney would be disconnected, it could cause such a CO problem.
So I called chimney-sweep, he checked the chimney (with endoscopic camera) and chimney is absolutely tight and alright.
I called another boiler-technician and he gradually, step by step checked gas pressure (correct), replaced a gas valve and finally replaced system board.
None of these helped.
Technician admitted that this boiler series is quite unusual in Czechia, and he has almost none experiences with it.
He also contacted Czech Vaillant support but they were not able to help us as well.
