--- Quote from: gmdodt on June 01, 2018, 01:54:38 pm ---so say after 2 more weeks it still hasnt tripped with the pump disconnected.  What do i do at that point?  Obviously plug back in to see if it happens with it plugged in again, but what other trouble shooting is there?  Can i take any electrical readings at the pump terminal or anything?

   You can put a volt meter on it and confirm it is sending 220 to the lead when you press the pump btn.  But if it was likely tripping during the purge cycle when the pump was hooked up it won't matter.    I would say plug it in, how long has it been, 10 to 12 days?   I might give it another week.  Then run normally and see if it trips.   After that hard to say if it trips again just short of replacing the board not much left to try.    Spa is now heating and running normal?  If so again my thoughts are still pump 2.

Yea, ill report back after another week or two of leaving pump 2 disconnected.  When i reconnect it ill take some readings.  The service guy had a megger the lines into the break from the tub and there was no material leakage (many weeks ago)...just weird

Botswana:
So it is now July 5, and I still only have the primary pump plugged in and it still hasn't tripped in over a month a half.  I suppose I will plug the pump back in in a few days and see if it trips.  What are peoples thoughts on whether it is the pump, board, or possibly something else?

Jacuzzi Jim:
 90% it's pump 2

Botswana:
is a bad or failing capacitor the possible culprit?  If so, thats replacable on these pumps, no?
