Display shows E15; unit may shut down and an audible alarm may sound, sometimes accompanied by water in the base.

Safety first: Unplug the appliance before tipping or removing base panels.

Steps to address E15:

• Check for water: Carefully pull the wine cooler out and inspect the base for standing water. Use towels or a sponge to remove any water.
• Locate float switch: Many Siemens units have a float switch in the base tray. Ensure it moves freely and is not stuck in the raised (alarm) position.
• Clear drain channel: Inside the cabinet, locate the condensate drain hole (usually at the rear). Use a soft pipe cleaner or flexible brush to clear any blockage.
• Inspect drain hose: From the rear, follow the drain hose from the liner to the evaporation tray above the compressor. Check for kinks, disconnections, or cracks.
• Dry thoroughly: Allow the base area to dry completely before restoring power so the float switch resets.

If E15 recurs frequently, there may be a persistent leak or liner crack that requires professional inspection.
