We were using the hose to clean a patio and because we needed the whole length we pulled its full length out of the reel. It did not feel like anything clicked or broke when doing so, it was done in a fairly gentle way.
The problem is that the reel does not rewind the hose anymore. There is a lever button on the side to switch locked and unlocked positions but toggling it has no effect.
When trying to spin the wheel manually with the fingertips, it does not move. As if the spring is maintaining it in locked position.
What can we try?
