Jets are weak, or no water comes out of the jets even though the pump is running.

Safety first: Turn off power before removing filters or opening unions.

• Clean or remove filter: Take out the filter cartridge and rinse thoroughly. Test jet flow briefly with the filter removed.
• Open valves: Ensure all diverter and slice valves are fully open and positioned to send water to the desired jet zones.
• Bleed air: Loosen the pump union slightly until water flows steadily, then retighten.
• Check jets: Remove individual jet inserts (if removable) and clean out debris or calcium buildup.
