LG refrigerators can collect water inside when defrost water is not draining, a door seal leaks warm air, or water from the filter or ice system travels into the cabinet.
Safety first: Unplug the appliance before touching accessible hoses, filters, or panels. Do not bypass a door or lid switch, probe live wiring, or continue using an appliance with smoke, a burning smell, sparking, a hot plug, repeated breaker trips, or water near electrical parts.
Most Likely Causes
1. Restricted defrost drain
Locate the source before moving the refrigerator.
2. Door gasket not sealing
Turn off water for an active water-system leak.
3. Blocked air paths
Do not force access to internal panels.
4. Ice-maker meltwater
Locate the source before moving the refrigerator.
5. Filter housing drip
Turn off water for an active water-system leak.
6. Cabinet not level
Do not force access to internal panels.
Step-by-Step Diagnosis

Step 3: Inspect accessible filter or ice area
Stop if water reaches electrical parts.
Step 4: Check door closure

Step 5: Review defrost symptoms
Avoid sharp tools near liner or coils.
Step 6: Call service for hidden lines
Stop if water reaches electrical parts.

A qualified technician may inspect the defrost trough, drain tube, evaporator cover, filter housing, ice maker, dispenser tube, gasket, and leveling system. The symptom alone does not confirm a failed part.
When to Call a Professional
Book service if the safe checks do not solve the problem, a code or symptom returns, or the repair requires meter testing, internal wiring access, appliance removal, or disassembly. Stop immediately for burning odor, sparks, hot wiring, breaker trips, or water near electrical parts.
