Anchor retreival

I have a brand new 250as and having moved up from our previous boat with no windlass was really looking forward to easy retrieval with the electric windlass on the 250
My problem is that under the slightest load the thing trips !!
Has anyone had experience of this ? Am I doing something wrong ?
Also do any of you guys use the Alderney ring method for retrieving the anchor and if so where do you secure the line for towing ? As the new bow roller is not up to the job
Any advise would be welcomed
