Today,finally a nice day in Michigan and I set out to get our hottub ready for use after a long, cold winter. As I usually do, I had dewinterized it according to the manual. I started putting water in, and it becan to leak out the backside, the side that has the moto-massager. I found this forum and thought I'd start here. How do you get inside that part to look to see if a piece of pvc or piping needs to be replaced? I removed the four screws on the main door and can't see that area from there. Thanks.
