Pump display shows E07; pump may not respond to keypad commands or external control.

Safety first: Turn off power at the breaker before removing any covers.

Steps to troubleshoot keypad/communication issues:

• 1. Inspect keypad for damage: Look for cracks, clouding, or water droplets under the keypad overlay. Any sign of water indicates a compromised seal.
• 2. Check keypad cable connection: If accessible per Pentair instructions, gently reseat the keypad ribbon cable into the drive board connector to ensure a solid connection.
• 3. Test basic functions: After restoring power, try starting and stopping the pump from the keypad. If the display shows E07 and buttons do not respond, the keypad or control board is likely defective.
• 4. Verify external control wiring: If connected to automation (e.g., Pentair automation relay), temporarily disconnect external control wires and test the pump in standalone mode to rule out external communication issues.

If E07 persists, replacement of the keypad assembly or entire drive/control module is typically required. Consult Pentair service documentation or a qualified technician.
