E15 error; freezer may show continuous alarm and may shut down cooling as a safety measure.

Safety: Unplug the freezer before tipping or removing panels. Water and electricity are a dangerous combination.

Steps:

• Check for water: Pull the freezer away from the wall and inspect the base for water or ice. Some Bosch models have a float switch in the base tray.
• Drain water: If water is present, carefully tilt the appliance slightly (with assistance) and soak up water with towels or a sponge. Do not tip excessively to avoid oil migration in the compressor.
• Clear defrost drain: Access the rear interior panel and locate the defrost drain hole below the evaporator. Use a flexible plastic probe or warm water to clear any blockage.
• Inspect drain tube: From the rear, locate the drain tube leading to the drip tray above the compressor. Ensure it is not kinked, disconnected, or cracked.
• Reset error: After drying the base and clearing the drain, reconnect power. If E15 clears and does not return, monitor for future leaks.

Important: Persistent water in the base may indicate a hidden crack or insulation issue and should be evaluated by a professional.
