Water accumulates inside the ice bin or cabinet instead of draining away.

Safety first: Disconnect power before clearing drains.

• Clear visible ice: Remove ice from around the drain opening in the bin or sump. Use warm (not hot) water to melt blockages.
• Flush internal drain: Pour warm water into the drain opening and observe flow at the drain hose outlet. If slow, disconnect the hose and flush it thoroughly.
• Check hose routing: Ensure the drain hose slopes continuously downward to the drain and does not have high loops that trap water.
• Verify drain pump operation: If your Gram model uses a drain pump, listen for it during the drain phase. Replace the drain pump if it does not run or pump effectively.
