Lever arm won't stay up

I recently rebuilt my La Pavoni Professional and found that the lever arm slowly falls to the down position after lifting. Does this mean I have an improper seal somewhere? The lever does stay upright after the preinfusion.

My Cremina 67 and LaPavoni Europiccola both have no springs. The normal lever position is down. Only after using them and they're turned off for a bit I think a vacuum develops and the levers creep up and they only do that when the piston seals and chamber are fairly clean and lubed.

Nothing wrong. Instead, like mrgnomer said, it means the piston seal and chamber are clean and lubed very well if there is no leak.

It's rare that they stay up. You'll see this if you have freshly replaced the gaskets and it makes a good seal, but normally the lever will relax into the down position.
