It is connected through my Hayward salt water generator...

Heater connected through a SWG makes no sense.

Start with the circuit breaker the heater is attached to. Check that it is not tripped and reset it.

Post pics of your equipment pad and all your pool controls.

Looks to me like the heater power comes from the Hayward box.

Open up the Hayward box and post a pic of its inside wiring.

So it looks like your heater is wired to the same power terminals as the Aquarite SWG.

Do you have a multimeter?

Correct the panel is wired to turn on at the same time as the heater...... I believe the Pool Pump controller will prime / run for 5 minutes THEN sends power to the SWG/ Heater so they can power on.

The SWG is powering on and functioning as normal...

Here is the snap shot of the panel..... I'm pretty mechanically inclined but I SUCK at electrical ........ Does this picture tell you anything ?? I have checked the wiring connection from the SWG into the heater and those connections look solid.... no mice chewing or any bare wires that I can see.... doesn't appear to be too obvious ... at least to me
