I have just got a second hand spa. It was working great until I tried to set timer I must have pushed something wrong because it does nothing now even though I shut the breaker off overnight. When I turn breaker on spa reads CL with heater icon and runs for a min the it reads P1 2 and has a clock symbol below it then shuts off and does nothing no matter what button I push. Please someone help did I break it gosh I hope not... Thanks in advanced Alana
