“Err 07” appears and the unit may regenerate at incorrect times or not at all; time-of-day may reset unexpectedly.

Safety first: Disconnect power before removing the control panel.

• Verify power source: Confirm the outlet supplying the Morton softener is delivering stable 120V AC (in North America) and is not controlled by a wall switch or GFCI that frequently trips.
• Inspect power cord and transformer: Check the power transformer and cord for damage, loose plugs, or overheating. Replace the transformer if it is warm with no load or shows signs of failure.
• Check control board connections: Remove the control panel and ensure the low-voltage connector from the transformer is firmly seated on the board.
• Reprogram and monitor: Plug the unit back in, set the correct time and hardness, and observe over 24–48 hours. If the time resets or Err 07 reappears without power loss, the board’s memory/backup circuit is likely failing.
• Replace control board: Install a new electronic control board compatible with your Morton model. Transfer any jumper settings or programming as specified in the service manual.
