Ego single axle caravan mover fault

wye

Hi all ....

I have an Ego mover on my caravan which has had only limited use ,today it won't work !

I power it up the green and the blue light come on the back to green only , it starts to move then stops and the red light flashes ?

i have turned it on and off hoping for a reset , no joy ,

i have read the trouble shooting paper work that came with it and it mentions no faults of this type .

any advice welcome please
