Why does my ice machine have water in the bottom?

Finding standing water pooled in the bottom reservoir or collection bin of a residential or portable ice machine is typically caused by a blocked drainage port, a failing water pump, or an incomplete harvest cycle. In countertop ice machines, a clogged silicone drain plug or a scaled-over water return hole can prevent excess melted water from flowing back into the main reservoir. In refrigerator ice makers, water pooling in the bin usually indicates that ice cubes melted due to a temporary freezer temperature spike and fused together. You can troubleshoot drainage easily by inspecting internal ports. You can verify that your corrective action is successful when clearing drain blockages, descaling water pumps, or discarding melted ice clumps restores proper drainage and dry storage.
