I've been getting these codes for a while now, and it's obvious that no chlorine is being generated even when it's set to to 100%. The cell is less than 2yrs old, it hardly has any scale, and the sensor is clean. There is a voltage at the cell pins (around 20v). The one thing that looks like an issue is on the controller daughter-board, the relay looks damaged. Could this be the cause of the issue? If not, any other ideas?
