I have the same problem with my 3612DS and it is one of the circuit breakers tripping and then reseting. Some day when I have an extra "body" with me I will be able to figure out which one it is. Since they are right next to each other it is hard to tell by the click when it resets and by the time I go from the switch to the pump to look at my meter it resets!! One day I will figure it out. Then I will post my findings. Good luck in your search - hope this helps some.
