I recently picked up a 1996 Marquis Voyager from an elderly lady who had just purchased a home and needed to get rid of it. When I picked it up, there was clean water in the bottom like it had ran recently. The hot tub had not been winterized so there were a few leaks/cracks I had to fix but nothing major. It appears to have been taken care of really well and nearly all of the plumbing has been replaced. I have it connected correctly and filled up with water. The digital pad does not show any error codes, all of the pumps work, the heating element has been replaced and it still won't heat up.
