Pentair Pentair IntelliChlor IC40 Salt Chlorine Generator NO CELL Error Fix: No Cell Detected

Error code NO CELL on the Pentair Pentair IntelliChlor IC40 Salt Chlorine Generator means: No Cell Detected. The IntelliChlor power center cannot detect a cell connected to it. No chlorine generation is possible. Common causes include the cell not physically connected (the cell must be properly secured in its plumbing housing with the electrical cable connected to the power center), a wiring fault in the cell cable, corroded connections at the power center terminal, or a completely failed cell with an open circuit. Check the cell cable connection at both the cell housing and the power center. Inspect for corroded or green-colored terminals. Try disconnecting and reconnecting the cell cable. If the cell is properly connected and the cable is intact, the cell has failed and needs replacement.
