I have the EasyTouch 4. Everything works fine in spa mode. When I turn if off, it does a minute or two cool-down circulation and then immediately goes into spillway mode, dumping the entirety of hot water. It stays in spillway until I turn that off. Then, it reverts to pool mode, slow setting, which I have to turn off. Where should I start if I want to troubleshoot the programming. Normal and needed for some reason I don't know yet? I don't think I would ever get my pool-school/Pentair back out, as he bailed and disappeared on me after I declined his weekly pool service.
