Problem with Sly300 CB22 not closing

[Del]

Hello.
My sliding gate sly300 opens only, but wont close when key fob button Is pushed To close (i put new sensors on the wall and the same problem).

When I push the button I hear the motor click To try and close, but wont close. Have tried may times to reset and re-program with no success. I also replaced the capacitor, no joy.

For some reason the gate will not "learn" in program mode and won't travel between positions as expected in learn mode.
I have completed the jumper step many times but makes no difference.
Please help.

All fixed reed switch gone in gate position sensor. Hens wouldn't let gate closed.
