Update:
I called the ebay dealer where I purchased the Dolphin Dynamic. He had to call Smartpool (distributor) to see if he could get reimbursed for the dolphin before he could offer me any kind of refund. The next day Smartpool called and offered to give me a new "in the box" Dolphin. Both parties said they don't give refunds.
I guess all ends well only if my new Dolphin says heathly. I have to say Smartpool has been very good with communication with me and did the right thing. Their repair techs however need more schooling. IMHO
