What causes fault code GEN-DUST1 (Dust Collection System Alarm)?

Filter bags or cartridges clogged — need cleaning or replacement. Dust collection bin full — needs emptying. Ductwork blocked or collapsed. Fan motor or belt failure — reduced airflow. Pulse-jet cleaning system not functioning

How do I fix fault code GEN-DUST1?

Check differential pressure gauge — high reading = clogged filters. Empty dust collection bin if at capacity. Inspect ductwork for blockages — check blast gates are open. Verify fan motor operation and belt condition. Check pulse-jet system — solenoid valves, compressed air supply, timer. Replace filters if cleaning cycle cannot restore airflow

Field Trick

Put your hand near a pickup point. If you don't feel suction, either the blast gate is closed, the duct is blocked, or the fan has failed. Work from the pickup back to the fan.
