Cutting the frame??
If the factory is involved, there is no need for another dealer opinion, IMO. Â The factory support should give the tech the proper precedures to fix the problem. Â After all, it is the factory's warranty. Â I'll bet they will fix this without cutting anything, though they may want to remove the spa. Â If they do have to cut the frame, I would insist on a new spa as htotubdan stated.
