CODE Flashing White LED Clean Filter Severity: Medium Difficulty: Intermediate

Filter Sensor Loop Lockout

The main microcontroller has entered an airflow protection lockout loop. Differential pressure or thermistor-derived mass airflow measurements across the handle intake cage indicate impedance exceeding factory threshold (<0.8 kPa drop deviation), or micro-switch optical alignment sensors have detected persistent cage unseating.
