Looks fine.

Have you fixed the problem in the sub-panel?

I don't see any problem with the way that his subpanel is hooked up. Now, I don't generally do any work in the sub-panels, just the tubs. But the three HotSpring tubs that are hooked up at my store right now have the breakers in the same position.

Did you ever check the heater for continuity or confirm voltage at the heater relay board? Did you check the thermal cutoff switch (red button) on top of the heater to see if it's tripped?

guess what? i am only getting 110v from the main where the 50 amp breaker is.

Amazing hoe easy it is to fix stuff when you have the proper tools

btw- Pretty sure I'm losing my mind- the subpanel is fine

Yes, I got 220v from the main panel now but I have another question.

The white wire that is coming from the hot tub from the 5th position in the IQ2020 control board, does that connect to the 20 amp or 30 amp breaker in the subpanel?

I had it connected to the 20 amp, but I dont seem to have power going to the heater, and when I connect the white wire to the 30 amp breaker, the 20 amp breaker trips.

what gives?

if it's a 6kw heater, no neutral to the 30amp. 30 amp is for the heater. Vise versa for 4kw.

The neutral is the way they bring the 100v circuit in to run the circ. pump and the control circuit.

Dan the spa man was correct about why my water was not getting hot. It was the reset button on top of the heater, or the thermal cutoff switch as he calls it. Under the two tubes of the heater and under a layer of tape, there was the button. I depressed it, and within one hour of running, the water was getting warm. Two hours later the water was at 85 degrees, and the water temp was originally about 60. Three hours later the water was at 92 and still rising.

There was nothing wrong with any of the wiring previously posted in the string. I want to thank everyone for the input. The internet, specifically these forums are a vital source of information that saves the average consumer money.
