Robot vacuum shows C17; water tank or mopping module error on Dreame models with mopping.

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

• Reinsert tank: Remove and firmly reinstall the water tank until it clicks into place.
• Clean contacts: If your model uses electrical contacts to detect the tank, clean them gently with a dry cloth.
• Check water level: Ensure the tank has sufficient clean water and that the cap is properly sealed.
• Prime the pump: Run a short mopping cycle on a hard floor and check if water wets the mop pad. If not, gently tap the tank to release air bubbles.
• Inspect for leaks: Look for cracks in the tank or loose seals that could affect pressure.
• Replacement: If the pump does not run or the tank is not detected despite clean contacts, replace the water tank assembly or the internal water pump module as applicable.
