I recently installed the 28675EG pump and filter with no problems. The pump ran according to instructions on an 8 hour schedule going in to sleep mode as described for the first two weeks. Over the past three days I have found the pump to be running 24-7 even though the LED shows SLEEP. I have tried unplugging it, resetting the time option to 8 hours, switching from FP (pump only) back to normal timer mode, back washing and all else I could think of but it still runs all day and night until I turn it off. Has anyone seen this or know what to do about it? Thank you in advance for any information you can provide.
