Self cleaning pool and the jets do not pop up anymore?

Clogged Jets: The jets may be clogged with debris, such as leaves, dirt, or algae. Check the jets and remove any blockages.

Air in the Pipes: If there is air in the pipes leading to the jets, it can prevent them from popping up. Try bleeding the air from the pipes by opening the air relief valves on the pump or filter.

Broken or Damaged Jets: The jets themselves may be broken or damaged, preventing them from moving properly. Inspect the jets and replace any that are damaged.

Control System Issues: The control system for the self-cleaning pool may be malfunctioning, preventing the jets from operating correctly. Check the control panel and ensure it is functioning properly. If necessary, consult the manufacturer's manual or contact a pool maintenance professional for assistance.

Motor or Pump Issues: The motor or pump that powers the jets may be malfunctioning, preventing them from generating enough pressure to pop up. Check the motor and pump and ensure they are functioning correctly. If necessary, contact a pool maintenance professional for assistance.

It is recommended to consult a professional pool maintenance technician to properly diagnose and fix the issue if you are unsure about the cause.
