Quick answer
Turn ice production off if water is spilling, then identify whether water is overfilling the tray or ice is spilling from the bin. LG links tray overfill to water pressure and model-specific design, while a displaced bin can spill cubes. Keep it off and request service if the condition persists.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Turn the ice maker off if water is spilling and note whether water is above the tray or only cubes are outside the bin.
Expected result: Water is above the tray, or cubes spill without liquid overfill.
Next step: Use the matching checks and keep production off if water continues.
Why this matters
Why: Tray overfill and bin positioning are separate paths.
-
Check 2
Remove and reinstall the ice bin only as the model allows, checking for clumps or objects that prevent full seating.
Expected result: The bin was displaced or blocked, or seats correctly.
Next step: Clear only loose clumps and seat it fully; continue if tray water still overfills.
Why this matters
Why: LG says an improperly inserted bin can cause cubes to fall outside it.
-
Check 3
Use the model guidance to assess water pressure or a visible supply restriction; do not disconnect a pressurized line.
Expected result: Pressure is outside the model guidance, or visible supply is normal.
Next step: Use qualified plumbing or appliance service and keep the maker off if overfill returns.
Stop if: Do not bypass sensors or leave water entering an overflowing unit.
Why this matters
Why: LG says high or low pressure can contribute to tray overfill or dripping.

Decision map
Find the observation that best matches what you see, then follow the next safe action.
-
PATH 01Next step
What you see
Cubes spill because the bin is displaced or clumped, with no water above the tray.
Do this next
Keep the bin fully seated and clear loose clumps as permitted.
Why this path and its safety boundary
Why it matters: The storage path caused the spill.
-
PATH 02Next step
What you see
Water rises above the tray or forms joined slabs and pressure is abnormal.
Do this next
Keep the maker off and use qualified service.
Why this path and its safety boundary
Why it matters: Water delivery or valve closure needs attention.
-
PATH 03Next step
What you see
The bin seats and supply is normal but tray overflow returns.
Do this next
Request LG service with the exact model and spill pattern.
Why this path and its safety boundary
Why it matters: A model-specific sensor, valve, or control fault needs diagnosis.
When checks do not resolve it
Need a professional?
Request service if water keeps entering, pressure correction does not help, or overflow returns with a correctly seated bin.
Common questions
FAQ
How can I tell tray overflow from bin overflow?
Water above the tray or joined slabs point to the fill path; loose cubes outside a displaced bin point to storage positioning. Check both before ordering parts.
