My pool filter won't automatically or manually shut off. I have a Hayward Aqua Logic system. Recently I've noticed my pool filter won't automatically shut off according to the timer I have set. When I try to manually shut it off, it continues to flow, even though the control pad will toggle between off and on. The only way I can get it to shut off is by cutting the power. It's hit or miss....some mornings it works fine, others..not so much. Is this a problem with the filter relay? Thanks in advance.
