Fortunately for me I bought mine from Costco which has an astounding return policy. Hopefully I won't have to use it.

Carl, did you send the unit to an authorized service center or back to the manufacturer? It would be really nice if another member in your area could let you borrow their dolphin. Then you could at least have verification that it's your unit and not your pool ph or temp.

What EXACTLY is Costco's return policy, as I just bought one from them 10 days ago and am now worried based on Carl's experience.
