- CommonIce maker overfilling from a stuck valveExcess water beyond the tray's capacity spills over and pools at the bottom.
- PossibleCracked ice maker tray or water line fittingPhysical damage lets water escape before it reaches the ice tray properly.
- PossibleFreezer not level, causing water to pool in one cornerAn unlevel unit can direct normal condensation or minor drips to one low spot instead of draining properly.
What to do
- Unplug the unit and remove all food to access the floor of the freezer.
- Look for the defrost drain (usually a small hole at the back or bottom) and clear it gently with warm water or a pipe cleaner.
- Check that the freezer is level using a level tool, adjusting front feet if needed.
- Inspect the ice maker tray and nearby fittings for cracks or looseness.
