I have an above ground 24 by 24 pool. Today my on and off switch will not turn on. It moves in a circular motion now and normally in goes left to right. I have a sand filter, the housing unit says dough boy on it. I brought the house a few months ago and the previous owner didn't have the book. The pool is only 2 years old. I am having a hard time finding someone to look at my pool and filter. Help.
