No water coming out of water filter. The water is not going from the plastic water tank reservoir

Question

The water is not going from the plastic water tank reservoir into the internal chilling tank. Therefore the internal tank is empty. I have changed the filter to no avail. When I put the resevoir in position 1 bubble comes up but water does not continue to flow into the internal tank. If I remove the reservoir I can push up the valve and the water runs fine. The motor still runs when i push the button.
I put this under electric kettles as i could not find water filters.
