To fix the control board flashing issue on your EcoWater ESD 518, try the following steps:

1. Check the RECHARGE Indicator: If the display is flashing "RECHARGE TONIGHT," press and release the RECHARGE keypad once more to cancel the regeneration.

2. Power Cycle the Unit: If the display is blank, the softener may have lost power. When power is restored, the timer should retain the correct time for several hours.

3. Inspect Wiring and Power Supply: Ensure the unit is properly connected to a 120V AC power source and that all wiring is secure.

4. Check the Turbine Sensor and Motor: The flashing may indicate an issue with the turbine sensor or motor. Verify that these components are properly connected and functioning.

5. Reset the System: If the issue persists, try unplugging the unit for a few minutes and then plugging it back in to reset the control board.

If the problem continues, consider contacting an EcoWater dealer for further troubleshooting or repairs.
