What Small, Hollow, or Clumped Ice means (lg ice maker bad ice)
An lg ice maker bad ice complaint — small, hollow, or clumped cubes — is an observable condition rather than a fault code. Hollow or small cubes usually mean the mould is underfilling, while clumping happens when ice melts slightly and refreezes in a bin that is used infrequently.
Symptoms to look for
The signs below help confirm you are dealing with this condition rather than a different fault on your LG Ice Maker. You may see one of them or several together, and they can build up gradually or appear suddenly after a power event, a long door opening, or recent service.
- Cubes are smaller or partly hollow
- Ice freezes together into a solid clump in the bin
- Cubes vary in size from one batch to the next
- Clumping is worse when the dispenser is rarely used
Common causes
Several different faults can produce these symptoms. Working through the most likely causes in order helps separate a quick, owner-level check from a problem that needs trained service and the correct LG parts.
- Low water pressure or a clogged filter — underfills the mould
- Inlet valve restriction — limits the fill volume
- Infrequent use — ice partly thaws and refreezes into clumps
- Freezer temperature swings — soften then refreeze the surface
Troubleshooting steps you can try
Work through these checks in order before calling for service. Stop wherever you are unsure, or where high-voltage parts, gas, the sealed refrigeration system, or a heat-pump compressor are involved, and hand the rest to a qualified technician.
- Replace an old water filter with a genuine LG filter and discard the first few batches.
- Empty the bin and let a fresh batch build to check cube size.
- Use or empty the bin regularly so ice does not sit and clump.
- If cubes stay small or hollow with good pressure and a fresh filter, book service to check the valve.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the water filter, water pressure, inlet valve, freezer temperature, and bin usage. The correct part for your LG Ice Maker is matched from the model and serial number, and genuine LG components are fitted rather than generic substitutes so that performance, safety, and the appliance’s long working life are all protected. Confirming the failed part before ordering avoids replacing more than the fault actually requires.
When to call a technician
If ice stays small or hollow with adequate pressure and a new filter, a technician should test the inlet valve fill volume and the ice mould. When the fix calls for trained service, book a visit through our scheduling page and an experienced, qualified technician will diagnose and repair it.

Prevention and care
Regular care keeps this condition from returning on your LG Ice Maker. Keep filters, vents, and the condenser or exhaust path clean, avoid overloading or blocking airflow, check that doors and seals close cleanly, and follow the LG maintenance guidance for your model. Note when the symptom first appeared and what changed around the same time — a recent load, a warm room, a power event, or recent service — because that detail often points a technician straight to the cause and keeps the repair simple.
