Hi, I have a 4 year old haywood swimpure extreme 25k. My pool is 13000 gal. The chlorine level in my pool is at 8. My pool company said the cell was bad so they changed it. After recalibration and about running for 30 minutes the instant salt and the cell amperage always goes to 0. Today they changed the pcb board thinking that was all that was left. It's still doing the same thing. Also I have a new flow switch. Anyone have any advice on what to do next. I do have a leak in the pool where it's using about a inch a day.
