I have had excessive leakage from the bottom port on my Lelit Bianca (not the bottom of the group head but the one exiting the machine itself). This occurs even after the machine is fully preheated.

I have the top off and had noticed water slowly exiting the antivacuum valve. I took it off and replaced the whole valve. I no longer see water coming from the antivacuum valve to the port.

The problem is unresolved. I'm noticing the water seems to flow from the safety valve. Should there be any water coming from that after preheat? Is replacing this valve as well the likely solition?

Try disconnecting it from the hoses to see if that solves the issue.

I wouldn’t expect water from a safety valve, isn’t that thing just there to prevent a situation where the pressure continues to build? Also, I don’t think that even has a hose attached to it. Can you send a shot of what you’re seeing leaking?

Just for the archives, replacing the safety valve did correct the issue after replacing the antivacuum did not. This happened after about 4 years, pretty much always have the service boiler on when the machine is on. Poland spring water but I guess these parts just wear out after a while

Nice work! I’m sure you’ll get another 4+ years on the new one.

I actually have the same problem and haven’t bothered with the safety valve. Do you happen to know the part number?
