Suction path blocked error, unit detects high motor load and stops

Safety: Unplug before clearing blockages.

• Check hose: Detach the suction hose and look through it. Use a flexible rod or broom handle to gently push out any clogs.
• Inspect floorhead: Remove the floor nozzle and clear hair, threads, or debris from the intake opening.
• Clean tank filter: In the dirty water tank, remove and rinse any mesh or foam filters that protect the motor from debris.
• Check internal ducts: Open access panels and inspect the air path from tank to motor. Vacuum out dust and debris.
• Test suction: Reassemble and test. If the error recurs with clear airways, the motor current sensor or PCB may be misreading and require service.
