Warehousebroker

The electrician re-wired it back to 115v and it has been working just fine. Do you think that the breaker is bad and couldn't handle the load? He didn't have a different breaker with him to switch it out and test it at the time.

Recently acquired my parents Hotspring Sovereign 2003 model. Had to replace heater relay board and small circulation pump. Panel lights operating as they shoukd now, spa is properly primed from what I can tell, ozone with bubbles working as they should. Now when I turned on heater breaker, set temp to 102, after about 5 minutes the breaker trips. I feel the water warm where the bubbles rise so it seems to be heating. Heater is Watkins no fault 6000. Any suggestions or advice would be helpful.
