Jets are weak or some seats have little to no water pressure.

Safety: Turn off power before removing the filter or opening plumbing unions.

• Step 1 – Clean filter: Remove and thoroughly rinse the filter cartridge. Replace if old or damaged.
• Step 2 – Check diverter valves: Adjust any topside diverter valves to direct flow to the desired seats.
• Step 3 – Open all jets: Turn each jet face counterclockwise to fully open.
• Step 4 – Bleed air: If the spa was recently drained, bleed air from the pump unions.

If flow remains weak, the pump impeller may be worn or partially blocked and should be inspected.
