Clack water softener frequently loses time and programming after power outages.

Safety: Unplug the unit before removing the control board.

Steps:

• Check manual: Determine whether your specific Clack controller relies on a backup capacitor or non-volatile memory for retaining settings.
• Observe behavior: If settings reset after short outages, the backup function is likely failing.
• Replace control board: In most Clack models, the backup component is integral to the board. Replace the electronic control board to restore reliable memory retention.
• Add external backup: Consider using a small UPS or battery backup on the transformer to ride through brief outages.
• Record settings: Keep a written record of all programming so it can be quickly restored if needed.

Note: Frequent resets can lead to improper regeneration and hard water; address promptly.
