Troubleshooting:

Drain pans accumulate condensate liquid as part of the normal refrigeration process.

• A drain pan may be more than half full of water at any given time depending on several factors.
• Drain pan condensation evaporates as the unit runs, so it is not necessary to empty it regularly.

To clean a Sub-Zero drain pan:

1. Remove the drain pan.
2. Empty the drain pan.
3. Use a mild detergent, baking soda paste, and water to clean and wipe with a soft cloth.
4. Rinse and dry thoroughly.
5. Replace the drain pan.

Note: Drain pans in most Undercounter and 700 Series units are not removable by the consumer. If needed, they can be emptied by using a large syringe (turkey baster) to suck up any water and residue.

If there is water under the crisper drawers, the drain tube may be clogged.

• Food debris, standing water, or ice built-up in the drain trough or drain tube located along the back wall may cause this.
• For a 200, 300, 500, or 600 Series unit, refer to 200/300-500-600 Series Refrigerator Drain Tube Cleaning. 
• For 400 (Wine Storage), 700 (Designer (Formerly Integrated)), 648PRO, and Legacy Classic (BI) Series, refer to Drain Tube Cleaning (BI-700-400-648PRO Series).
• Refer to Water Under Crisper Drawer for more information.
