FLO appears intermittently, especially when jets are on high speed or when multiple users are in the tub.

Safety: Turn off power at the GFCI before removing any components.

• Inspect skimmer and suction fittings: Remove any leaves, hair, or debris from the skimmer basket and visible suction grates.
• Deep clean filter: Soak the Beachcomber Microfilter cartridge overnight in a spa filter cleaner solution, then rinse thoroughly. Replace if pleats are collapsed or fabric is frayed.
• Check heater inlet screen: With power OFF and water level maintained, open the equipment bay and locate the heater inlet. Some Beachcomber heaters have a small screen or mesh; remove debris carefully if accessible.
• Test with jets on high: Restore power and run jets on high. If FLO appears only under heavy use, the jet pump low-speed winding may be weak and require replacement.

If intermittent FLO continues after thorough cleaning, schedule a technician to test pump amperage and inspect internal plumbing for partial blockages.
