Pump display shows E15 and the unit cannot be controlled locally; only remote commands work (or vice versa).

Safety first: Ensure the pump is in a safe state before changing control modes.

Steps to check:

• Check control mode setting: Using the Jacuzzi keypad, navigate to the control mode menu and verify whether the pump is set to LOCAL, REMOTE, or AUTO.
• Disable keypad lock: If a lock icon is shown, follow the manual procedure (often holding specific keys) to unlock the keypad.
• Temporarily disconnect automation: Remove external control wiring and power cycle the pump to see if local control returns.
• Factory reset: If settings appear corrupted, perform a factory reset and reconfigure.

If E15 or control conflict persists, the user interface or control board may be defective and require replacement.
