Titanium ventilate issues
Having done everything per the manual and all online info I can find, the "ventilate" message continues. It seems to be in the steam/hot water side and doesn't respond to wand cleaning. Gaggia has no solution.

Probably a broken/faulty/damaged "Steam Valve Cam".
Seem to be pretty prone to premature failure due to "wear and tear".
Remove the milk frother,checked to see if it is blocked.
This can cause the machine not to ventilate correctly.
They tend to block with old hard milk.
Another problem i have found is coffee grounds are getting caught in the flow meter(inside the machine)
