Why can't I put the laundry in the middle of washing the drum washing machine?

I'm using a tromm drum washing machine I stopped in the middle to add laundry and opened the door, but the door didn't open

It says weight detection and a red light pops up.

Can't you add laundry in the middle of a drum washing machine?

pu1. The new model is possible.
Not the old one.

pu2. It's impossible while the drum washing machine is running.
It's possible if there's a laundry add-on.
