Mhouse sl10 not closing

[Mark Reader]

Hi, I am wondering if anyone has any advise, my Mhouse sliding gate has developed an issue where it will only open. I can unlock it and move it to mid travel, using the remote or keypad it will only motor in the open direction, I can stop it but not reverse it, when it reaches the fully open pos’n the ecsbus lights repeatedly flashes 7times.
I’ve cleaned the board it looks ok(I think) 
Wondering if I need a new cl1s board but would like to exhaust other avenues first.
Cheers
Mark
