Possible Causes
Control locked in service mode, Child lock or installer lock active, Faulty keypad, Main control board failure
How to Fix / Troubleshooting
Safety first: No hydraulic work required for initial diagnostics.
- Check lock status: Look for a lock symbol on the display. If present, follow the Judo manual to disable child lock or installer lock (often by holding specific keys).
- Test keypad: Try multiple buttons. If none respond, see the keypad fault section and inspect the Judo keypad / front panel.
- Power cycle: Unplug the unit for 5 minutes, then reconnect and attempt to start a manual regeneration.
- Board replacement: If the display works but the unit ignores regeneration commands, the Judo main control board may be defective and require replacement.
