Watering pump does not work

I have 8 watering pumps that I use to teach kids to code with the M5s. Two of them do not work. Water does not flow, event though they make a noise. I tested all Watering units with the same Core2 on the same Groove port (B).
There is one difference that I can tell. When I blow through the inlet of working pumps - air gets out on the other side. When I do the same on the "broken" pumps no air comes out on the other side. This makes me think there is something blocked. Its a fresh pump that I ordered a while ago so it should not have gotten any dirt in it.
Is there anything I can do to get them to work? Anybody else with the same experience?

Carefully disassemble the impeller and check it’s moving freely

If you let the kids watch you disassemble and check the impellers you might inspire a future HW engineer instead of a future SW engineer.
So be careful and dont do that :)
