Unit Not Fully Powered On | System is in standby mode (not actually running) | App shows 0 ppm; no chlorine production; power light not green | In the app, power icon is white (not blue); power light on unit is red (not green) | In the app, tap the power button (turns blue) and press the physical power button on the unit (turns green). Device only starts detecting and displaying salt readings when powered on. |
No or Low Water Flow Detected | Pump speed too low / valve not fully open / dirty filter | Flow indicator light flashing; no salt reading | Confirm pump is running; check flow indicator light status | Increase water flow; clean filter; open valves fully; meet minimum flow rate: Horizontal ≥60 L/min, Vertical ≥90 L/min. |
Flow Switch Blocked by Debris | Flow paddle or impeller blocked by branches, leaves, debris | Flow indicator light flashing; salt reading not updating | Check if flow switch paddle moves freely | Remove debris (leaves, scale, hair, etc.); ensure paddle moves freely; re-test. |
Incorrect Installation Direction or Orientation | Inlet/outlet reversed / vertical installation with low flow | Flow light flashing; no salt reading | Check body arrow direction; confirm mounting orientation | Reinstall in correct arrow direction; horizontal installation preferred; ensure adequate flow. |
Salt Recently Added, Not Fully Dissolved | Salt reading delay after addition | Shows 0 ppm or unstable readings after adding salt | Look for undissolved salt crystals in water; confirm time since addition | Run pump continuously for several hours (typically ~24 hrs) before re-checking. |
Actual Salt Level Too Low | Not enough salt in water | Consistently low or 0 ppm | Test with salt test kit or strips | Add salt to recommended level (e.g., 3000–3500 ppm) and circulate evenly. |
Startup/Reading Delay | System just started up | Short-term 0 ppm after powering on | Observe for a few minutes after startup | Wait a few minutes; device displays reading after detecting water flow. |
Cell Scaling | Calcium scale buildup on plates reduces conductivity | Low or inaccurate salt reading; reduced chlorine output | Visually inspect cell plates | Clean cell; set polarity reversal time to 4 hours to reduce scaling. |
Test Strips Misleading | Oxidizers/chlorine affect strip color | Test strip reading higher than device | Compare strip and device readings | Use device reading as main reference; test strips may show higher values. |
E2 (Low Salt) Status | Controller detects low salt | E2 displayed; unsure if chlorine is being produced | Check code + observe chlorine production | In E2 state, unit still produces chlorine at about 50% output (reduced but not stopped). |
