OK, I am at my wits end here, did numerous searches and have come up with nothing, and I even remember seeing a post on this some time ago.
I have inspected the inside of the main unit for moisture, made sure the relay that the "Chicken Foot" is attached to is working right, it all looks ok to me and I can only get one direction of of my Jobo CPP2 when operating. If you look at the gear from the end away from the main unit, the spin is counter-clockwise. I even move the claw around to try to re-engage it, I hear the click of the relay and then there is a slight hesitation and then it keeps going the same direction.
Not really sure what to do here, as it works for one session one day, then the next batch it no longer reverses and today it never reversed.
