Display shows LOC and buttons do not respond.

Safety first: No internal work is required for this issue; power can remain on.

• Unlock keypad: Refer to your Hayward pump manual for the specific key combination (often holding two buttons simultaneously for several seconds) to disable the lock.
• Check automation control: If the pump is under control of a Hayward automation system, local control may be limited. Use the automation interface to adjust settings or temporarily disable external control.
• Inspect keypad: If buttons feel stuck or unresponsive, gently clean around them with a dry cloth. Do not spray cleaners directly onto the keypad.
