Display shows E8 and no water is being picked up; suction sound is weak.

Safety first: Disconnect from mains before removing tanks or covers.

• Empty and reseat the dirty water tank: Ensure the tank is not full and that it is pushed fully into place. Check that the lid is latched and the gasket is intact.
• Inspect seals and gaskets: Examine the recovery tank gasket, nozzle-to-body seal, and hose connections for cracks or deformation. Replace any damaged seals.
• Clear suction path: Remove the floor nozzle and hose. Look through the suction channel for obstructions such as carpet fibers or small objects. Use a flexible brush or compressed air to clear blockages.
• Check airflow sensor tubing: Some models use a small silicone tube from the suction channel to a pressure sensor on the PCB. Ensure this tube is not kinked, split, or disconnected.
• Test without accessories: Run the unit briefly with only the base connected. If suction is strong and E8 disappears, the issue may be with an accessory tool or hose.
