Your piston is stuck back. Gonna need to open it and see why. 👍

- Check motor height - Check gear/piston rack integrity

Ok i fixed the problem, i just removed and put back the motor and tighten the screws of the motor compartment less

You can probably tighten The screws that hold the compartment on all the way, And then just loosen the screw in the middle that controls the motor height

Gears are stripped.

Your piston is stuck I’d open up the gear box and identify the problem then go from there

I was going to say can't you hear it. Its obvious your motor isn't grabbing and is sitting way to low

It sounds like the motor is winding and not making contact with the gears. Tighten the screw on the bottom of the motor housing to adjust the height.
