Flow rate below minimum threshold – Increase the flow rate. 3. Impeller blocked by dried liquid – Remove, clean, and ensure free rotation. 4. Impeller obstructed by sealing material – Remove obstruction and verify impeller movement. 5. Improper installation near impeller – Reinstall correctly. 6. Excessive electronic noise or proximity to motor – Reinstall away from interference sources. - Faded or blank display: 1. Low or disconnected battery – Check or replace batteries. - Flow is normal but meter does not count: 1. Incorrect calibration – Recalibrate. 2. Impeller blocked or damaged – Inspect and ensure free rotation. 3. Impeller obstructed by sealing material – Remove obstruction and verify movement. - Low flow and meter does not count: 1. Impeller blocked by dried liquid – Clean impeller and confirm free rotation. 2. Flow rate below minimum – Increase flow rate. - Unable to calibrate: 1. Circuit board failure – Replace circuit board. 2. Button malfunction – Replace circuit board.
