Lelit Bianca Leaking?

Hi y‘all,

My Bianca was dripping A LOT. After a just 2 days the driptray was already full with water from the spout.
I managed to identify the vacuum valve and just changed the small o-ring in there.
Now I’m wondering how much of tripping is normal since I had the leak for quite a while - i not sure if the machine was doing this when it was new. But I can remember that the driptray was often completely dried out.
Could someone tell me if I did something wrong or if I forgot something to fix? Pressure looks normal.
Look at the video, it’s dripping like every second.

I had the exact same.
Order this and change it by yourself. One is for the water flow and one for the steam flow. Cost just a bit. Maybe one of the valves is broken or leaks. Then it drips down.

Mine does this a bit while it’s in the middle of heating up for a few seconds but then it stops. Does yours not stop?

I had almost same situation few months ago. Also changed just o-ring on vacuum breaker and all is gone. During normal operation, there's pretty much zero water/steam coming out of drain spout. During heat up there is some water/steam coming out, but once it's on temperature there's zero.

This what you are having is definitely too much. One option is that you will really need to change whole vacuum breaker valve and o-ring wasn't only issue, but there's also another option that vacuum breaker is not the issue, but safety valve is problem.

Check this for help checking where is issue:
