Phoenix Spa Pump On/off/on/off Issue (Balboa Components Inside)

[Snopczynski]

Hey folks, looking to have a xmas eve hot tub party here in Washington. We used the tub on Saturday (everything worked great), drained it last night, and refilled it today.

I turned the breaker to the tub back on, and pump 1 turns on/off/on/off/on/off over and over and over again. Intervals at about just under a second. Light on the control panel blinks on/off as the pump turns on/off.

Pump 2 works fine at all 3 motor settings (off, low, High).

I messed with all the buttons on the control panel with no change. It does say Pr (prime mode) on the screen when I fist turn on the breaker. I have let the pump run for about 5 minutes, still no change. I cracked loose the pump fittings to see of the system had some air lock issue, no change. As the pump turns on/off over and over again, I can hear a relay clicking down in the control box. I opened the drain and bled out any air there.

The tub was left uncovered last night, and it did rain here.

Pump 2 was replaced on the tub 2 weeks ago.

Only other thing I can think of is air in the heater element tube causing the relay to shut the pump on/off.

I also put pics below of the components this spa has.

Anyone have any ideas?

Here are the pics:
