Heater to hot

Suggest you test for 240V across J100 and J101 when the spa is calling for heat and verify you have proper voltage coming off the circuit board. Might have a bad relay and the spa is only heating on 120V and that is why it is taking so long to heat now.

Ok Remove the heater quick connect and inspect the prongs inside the quick connect to ensure they are good then test it there for power coming off the board when the spa is calling for heat.  If no power remove the circuit board and have a look on the back for burnt or darkened areas around the relays.

You have verified you have 240V at the red and black incoming wires? red to blk = 240V

I can see something metallic looking just above the heater quick connect behind the white Balboa sticker...What is it?

The heater light indicator is on and solid when testing? Because there is no burnt area on the back does not mean the relays are good. If you have 240 coming in to the board and the heat light is on and no error codes on the topside with no power coming off the board at the quick connect you need to find an electronics shop that can replace the relays. I normally have them do all the relays on the board.
