Get under it with something like a butter knife and lift with the knife while you turn it.

there was a techinal update on this machine a few months ago, the oil may be leaking from the swash plate housing

Yes the green light should go off

I had the same issue and after much exploring I discovered just a tiny bit of corrosion in the switch. To repair, remove the squegee section, and water bottle, so you just have the base unit. Then remove the bottom plastic cover and unfasten all the screws. Now remove the switch. With a fine Exacto knife and a magnifyer remove the switch and open it. Check it for corrosion this is whats causing it to stay on. Carefully scrape out the corrosion with the Exacto tool and then carefully reassemble. The light should switch off. You can also test it before reassembly just to make sure all the corrosion is gone.

Might need new batteries.Hope this helps
