Jets are weak or some jets do not have any flow even though the pump is running.

Safety: Turn off power before removing jets or opening plumbing.

• Clean filter: Remove and thoroughly clean or replace the QCA Spas filter cartridge.
• Check diverter valves: Rotate any topside diverter valves to different positions to balance flow between seats.
• Bleed air: Loosen pump unions slightly to release trapped air, then retighten.
• Clean jets: Remove individual jet inserts (turn counterclockwise) and rinse out debris. Inspect for calcium buildup and soak in a descaling solution if needed.
