Judo water softener does not start regeneration at the programmed time

Safety first: No internal work required for basic checks; keep covers closed.

• Check current time: Enter the user menu and verify the displayed time matches actual time. Adjust if necessary.
• Review regeneration mode: Ensure the Judo softener is set to metered or time-clock mode as desired. In manual mode, it will never regenerate automatically.
• Confirm regeneration time: Verify the programmed regeneration start time (e.g., 2:00 AM) and that the unit is not in vacation or standby mode.
• Check water usage: For metered models, ensure the flow meter is counting usage. If the display never shows flow, see the flow sensor fault section.
• Manual test: Start a manual regeneration. If this works but automatic cycles never start despite correct settings, the Judo main control board may have a timer fault and require replacement.
