Saeco Talea Giro brew unit leak diagnosis

How to use a magnet to bypass the door open sensor so you can find where the brew unit link is coming from.
You can see the SBS valve leaking on the upper left of the brew unit at 26 seconds into the video.

so how did you solve it? I am having the same issue, but didn't see a leak, mostly cause I don't have a magnet. But, is it a washer? O-ring that needs to be replaced? TIA

I replaced the SBS valve unit. Less expensive than replacing the brew unit. More expensive than just replacing the washer, but it's not available as a part.
