Genua Electric furler

Hello everyone
After my genoa had wrapped around itself several times because the engine did not stop, my genoa now only turns in one direction, unrolling.
In the bath I can hear a click on pressing the switch in the cockpit. I have already exchanged the cables and used a different switch. Always with the same result. It just works in one Direktion. 
Does anyone know advice?
I would be grateful for a recommendation.
