Jets are weak or some seats have very little water pressure even with pump on high speed.

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

• Clean or remove filter: Test jet strength with the filter removed. If flow improves, replace the filter.
• Adjust diverter valves: Rotate any topside diverter valves fully in both directions to direct flow to different seats. Ensure none are stuck between positions.
• Bleed air: Run the pump on high with all air controls closed, then open each air control one at a time to purge air.
• Clean jets: Remove individual jet inserts by turning counter‑clockwise and pulling out. Rinse debris from the back and from the jet body.
