Jets are weak or some seats have very little water pressure.

Safety first: Turn off power at the GFCI breaker before removing filters or jets.

• 1. Clean filters: Remove and thoroughly rinse all filters. Test jet strength with filters removed briefly.
• 2. Check diverter valves: Rotate any top-side diverter valves slowly through their full range to direct flow to different seats. Set them to the desired position.
• 3. Inspect jets: Remove weak jets by turning them counterclockwise and pulling out. Check for debris in the jet body or nozzle and clean as needed.
• 4. Air lock: If the spa was recently refilled, bleed air from the main pump unions.

If flow remains poor across the entire spa, the main pump impeller may be partially blocked or worn and should be inspected or replaced.
