I tend to agree with above, our hot tub has isolation valves for all the pumps and the heater. You, of course need to open the disconnect switch before doing anything. Then with any luck you will find a you-tube video of the heater replacement. However, you may want to make sure it is actually the heater that has failed. Ours has a dedicated fuse for the heater, and a relay that controls the heater, if either if these fails, no heat. A neighbor just had the computerized controls on their hot tub fail, and one of the items that did not work was the heater function, so IMHO, if you have the expertise, you may want to do some investigation before replacing the heater unit.
Hope this helps.
