Why is my LG refrigerator leaking from the bottom?
On the LG LMXS28596S bottom-mount refrigerator, a leak from the bottom is most often caused by defrost water not draining correctly (then overflowing into the base) or by a water supply connection that’s seeping and running down to the floor. Use the LMXS28596S owner’s manual to identify access points and safe handling steps.
Most common causes to check first
- Clogged defrost drain: Meltwater can back up and spill into the cabinet, then run out at the bottom.
- Drain tube issue: A blocked, kinked, or misrouted drain tube can send water to the wrong place.
- Water line or fitting seepage: Slow leaks at the inlet valve, tubing, or filter area can track down and puddle.
- Ice maker or dispenser drip: A small drip can collect and eventually show up as a bottom leak.
- Door not sealing: Warm air causes excess frost; during defrost, extra water can overwhelm the drain.
Quick troubleshooting steps (safe DIY)
- Unplug the refrigerator and remove food from the area you’ll access.
- Check where the water starts: inside fresh-food section, inside freezer, or only on the floor.
- Inspect the drain path: look for ice buildup or debris near the drain opening.
- Pull the unit forward and look for water trails near the water line and valve area.
- Clean condenser cover and vents (dust buildup can contribute to temperature swings and heavier defrosting).
Parts that may be involved
If you confirm the leak is related to the defrost drain routing, the compatible drain component for this model is the refrigerator drain tube 5251JA3003D.
| What you see | Most likely source | What to do next |
|---|---|---|
| Water under crisper area | Defrost drain backing up | Clear drain opening and verify drain flow |
| Ice sheet on freezer floor | Frozen/clogged drain | Defrost, then clear drain and tube |
| Water only behind unit | Water line/valve seepage | Tighten fittings; inspect tubing for cracks |
Why it matters
Bottom leaks can damage flooring and can also signal a drain restriction that may lead to ice buildup, odors, or inconsistent cooling if it continues.

What is the warranty on lmxs28596s?
For the LG LMXS28596S refrigerator, the limited warranty is: 1 year for refrigerator/freezer parts and labor, 5 years for sealed system parts and labor, 5 years for compressor parts and labor, and years 6–10 for linear/inverter compressor parts only (labor not included). See the LMXS28596S owner’s manual for the full warranty terms and coverage details.
Warranty coverage at a glance
- Refrigerator/freezer: 1 year (parts and labor)
- Sealed system (condenser, dryer, connecting tube, evaporator): 5 years (parts and labor)
- Compressor: 5 years (parts and labor)
- Linear/inverter compressor: years 6–10 (parts only; consumer pays labor)
What “sealed system” means
The sealed system is the closed refrigerant loop that makes cooling possible. It typically includes:
- Condenser
- Dryer
- Connecting tube
- Evaporator
If you’re troubleshooting a sealed-system issue, a common component in that circuit is the refrigerator filter dryer ADH73150208 (used in the refrigerant system, not the water system).
Quick comparison: parts and labor vs parts only
| Coverage type | What LG typically provides | What you may pay |
|---|---|---|
| Parts and labor | Replacement part plus service labor | Usually $0 (if approved and in warranty) |
| Parts only | Replacement part | Labor, trip charges, and related service costs |
Why it matters
Knowing which items are “parts and labor” vs “parts only” helps you estimate out-of-pocket repair costs, especially for compressor or sealed-system repairs that often require specialized tools and a qualified technician.

What is the most common problem with an LG refrigerator?
For the LG LMXS28596S bottom-mount refrigerator, the owner’s manual does not identify a single “most common” failure. In our experience across LG refrigerators, the most frequent complaints are cooling problems (warm fresh-food section, weak airflow, or frost buildup) and ice or water dispenser issues (see the LMXS28596S owner’s manual).
What customers most often notice
- Refrigerator section too warm or temperatures fluctuate
- Freezer OK but fresh-food section not cold enough
- Frost or ice buildup that restricts airflow
- Ice maker not making enough ice
- Water dispenser flow slows down
Common causes on LG French door and bottom-mount designs
These are typical root causes when symptoms point to cooling or airflow problems:
- Evaporator fan not running or running intermittently
- Defrost system issue leading to an iced-over evaporator
- Dirty condenser area reducing heat removal
- Door not sealing well, causing warm air leaks
- Sensor or control problem causing incorrect cycling
Parts that may be involved (model-compatible)
If troubleshooting confirms a failed component, these parts are commonly related on this model:
| Symptom | Most likely area | First check |
|---|---|---|
| Fridge warm, freezer OK | Airflow/evaporator | Vents blocked, fan running |
| Frost on freezer back wall | Defrost system | Ice buildup, defrost pattern |
| Slow water flow | Water filter/water supply | Filter age, supply valve open |
Why it matters
Cooling and airflow problems can push the refrigerator compartment above safe food temperatures even when the freezer still feels cold.
Helpful DIY guidance
- Use the diagnosing refrigerator evaporator fan problems video to match symptoms to an evaporator fan issue.
- If the water or ice performance is poor, follow the filter and flushing steps in the manual and consider the how to change the water filter in an LG refrigerator guide.
