Possible Causes

How to Fix / Troubleshooting
Safety: Unplug the ice maker. Be prepared for water spillage when disconnecting hoses.
- Inspect drain hose: Follow the drain hose from the back of the unit to the household drain. Straighten kinks and ensure the hose slopes downward with no traps that can hold water.
- Clear clogs: Disconnect the hose and flush it with warm water. Use a flexible brush if needed to remove sludge or scale.
- Check internal drain: Inside the bin or sump area, locate the drain opening. Clear any ice, debris, or biofilm buildup.
- Test drain pump (if equipped): On models with a built-in drain pump, access the pump from the rear or base. Check for obstructions in the impeller and test motor resistance. Replace the pump if seized or electrically open.
- Reassemble and test: Reconnect hoses securely, restore power, and run a cycle while observing for proper draining and absence of leaks.
