Dryer stops with water tank symbol lit even though tank is empty

Safety first: Disconnect power before inspecting sensors.

• Clean tank and float: Remove the water tank and clean it with warm water. Ensure any internal float moves freely.
• Check tank seating: Reinsert the tank firmly until it clicks. Some Siemens dryers use a micro-switch to detect tank presence.
• Inspect hose and pump outlet: Check the hose that fills the tank for blockages. Clear any lint or scale.
• Test tank switch: If accessible, test the tank presence switch or sensor for proper operation and replace if faulty.
