any one experience this, got it brand new a2 weeks ago. it ran fine for a week, this morning i woke up and it wasnt running, so i disco nected the line, cleaned the filter to see if there was any blockages. ofcourse there wasn't. I hooked it back up to the tank, it ran perfectly for about 5 minutes, then shut off. unplugged it, plugged it back in, ran for five minutes and shut off. this continued til i just unplugged it. i know the "smartpump tech" shuts the motor off for 2 minutes to purge any air, but tis supposed to turn back on afterwards...ha mine doesnt! whats wrong? anyone ever experience this?
