240V breaker trips with ozone gen OR blower plugged in. NO trip with pump plug only. got a "flo" indicator on the display, pump only runs for about 1 second, then shuts off for 5-6 seconds and keeps repeating cycle. removed the filter with no change. does this sound like a pump, blower, or ozone gen issue?

btw something was vibrating the hot tub like crazy just before the breaker tripped (had to have been the pump) but if it's a bad pump then why is the blower or ozone gen causing a breaker trip and not the the pump? Any ideas.
