I have a 9 year old pool I bought with a autopilot dig 220 system installed.
I recently replaced my SC 36 cell with a new RC 35/22 cell. I also replaced the power cord as recommended.
Now the Soft touch screen gives no reading at all,only a flashing red light.
I've cleaned the union screen , cleaned the cell and made sure the wire is connected properly,and still only the flashing red light. No reading or anything.
What part do I have to buy now?
