Possible Causes
How to Fix / Troubleshooting
Safety first: Disconnect power before removing the front panel or keypad assembly. Avoid using sharp tools that can puncture the membrane.
Step-by-step:
- Dry the panel: If the softener is in a damp area, gently wipe the control panel dry. Do not spray cleaners directly on the keypad; apply to a cloth first.
- Power reset: Unplug the unit for 5 minutes, then reconnect. Sometimes a full power cycle clears temporary keypad faults.
- Inspect ribbon cable: Remove the control cover and locate the flat ribbon cable from the display/keypad to the main board. Reseat both ends carefully.
- Check for corrosion: Look for green/white corrosion on connectors. If present, clean lightly with electronics cleaner and a soft brush, then dry thoroughly.
When to call a technician: If specific buttons never respond or E06 returns immediately, the keypad or user interface board likely needs replacement.
