Robot vacuum displays E19 or announces a water tank error on hybrid mop models; it refuses to start mopping.

Safety first: Turn OFF the robot and remove the water tank. Avoid spilling water into the robot body.

• 1. Reinsert water tank: Ensure the water tank slides in fully and clicks into place. Check for debris on the tank rails.
• 2. Inspect tank tabs: Verify that the plastic tabs on the tank that engage the presence switch are intact.
• 3. Check for leaks: Fill the tank and check for leaks around seals and the pump outlet. Replace the tank if it leaks.
• 4. Clean contacts/switch: If the tank uses electrical contacts, clean them with a dry cloth. For mechanical switches, use compressed air to clear dust.
• 5. Test pump: Start a mopping cycle and listen for the water pump. If it does not run and E19 appears, the pump or sensor may be faulty.
• 6. Replace components: Replace the iHome water tank assembly (with integrated pump and sensors) if it is not detected or the pump does not operate.
