I have the same Problem going on in the same spa, Who can help me? It has been 2 years since Mike left his reply... It's a Tiger River "Bengal" series and it leaking from the Right front corner "Right of control panel" of the spa from the bottom right corner and coming from a screen. I looked in the front panel and everything is dry as well as the right side panel. I also took off the corner trim and dry in there. I used a mirror to look under the corner and water appears to be coming from a little white tube about 1/2 inch in diameter from under the screen..
this model id from around 2004ish
