Spa frequently enters sleep or low-power mode unexpectedly, reducing heating and filtration.

Safety: No internal electrical work is required for basic mode adjustments.

• Step 1 – Review user manual: Check the Catalina manual for how modes and filter cycles are set on your specific topside.
• Step 2 – Lock settings: If available, use a settings lock or child lock to prevent accidental mode changes.
• Step 3 – Check for stuck buttons: Inspect the topside panel for keys that may be sticking or activating on their own. Replace the panel if necessary.
• Step 4 – Stable power: Ensure the spa's circuit is not subject to frequent power outages or flickers, which can reset modes.
