I took the panel
off, and check if I was getting power at the heater and it was.
I would say that is an impossibility unless all your heater relays are stuck closed, if you don't have power anywhere else. Verify you have power going to the spa pack, and if so, check both the input and output side of the transformer for your circuit board. If you have power going in, but not comming out of, your transformer, you will need to replace it. If the transformer is good, you may need to replace the topside control, and maybe even the main circuit board
