Clean-flow reference — the 90th-percentile flow seen for the same active program, reference type, and setpoint. Low- and high-speed sessions therefore have separate clean references, learned from at least five verified readings. The top status uses the percentage lost from this reference, confirmed across two fresh readings for the same program. This is an estimated clean reference; low flow can also mean a blocked basket or valve issue.

Direct pressure reading — this is the pump's reported PSI, not a value inferred from power or flow. The dashed clean reference is the lowest typical PSI for the same active program, reference type, and setpoint, so low- and high-speed sessions are compared separately. Use it alongside the analog gauge on the filter canister to validate how closely the two readings track.
