Yes.
When to stop immediately?
Stop if you notice: Water is actively flowing from the refrigerator and cannot be contained, You notice water damage to the floor, cabinets, or walls near the unit.
Symptoms You May Notice
Water pooling on the floor around the refrigerator
Visible water accumulation on the floor beneath, behind, or beside the refrigerator that appears during or after defrost cycles.
Water dripping inside the fridge compartment
Droplets or streams of water running down the back wall inside the fresh food section, collecting under the produce drawers.
Ice buildup at the bottom of the freezer
A sheet of ice forming on the floor of the freezer compartment, indicating the defrost drain is blocked and meltwater is refreezing.
Musty or mildew smell from the refrigerator
Standing water in the base pan or drip tray that does not evaporate normally produces a musty odor detectable when the door is opened.
Possible Causes
Frozen or clogged defrost drain
The drain hole at the base of the evaporator is blocked by ice or debris, preventing defrost meltwater from flowing to the evaporation tray. This is the most common cause of the 33E code.
DIY PossibleCracked water supply line
The plastic or copper water line running to the ice maker or dispenser has developed a crack from vibration, cold, or age, causing a slow drip inside the unit.
Requires ProfessionalFailed water filter housing gasket
The rubber gasket where the water filter inserts into its housing has deteriorated, allowing water to seep past the seal during dispenser and ice maker operation.
DIY PossibleSafe Checks You Can Do
-
1
Check for visible water
Pull the refrigerator away from the wall and look for water on the floor. Check the drip pan at the bottom rear of the unit for overflow. Inside, check under the produce drawers for water accumulation.
Use a flashlight to inspect the base pan — it is usually accessible by removing the front kick plate.

2
Clear the defrost drain
Remove the freezer rear panel to access the evaporator area. Locate the drain hole at the bottom. If frozen, pour a cup of warm water slowly down the drain to melt the ice blockage. Use a pipe cleaner to clear any debris.
A turkey baster filled with warm water works well for flushing the drain from above.
Tools required -
3
Inspect water lines
Check the water supply line running from the inlet valve to the ice maker. Look for cracks, kinks, or moisture on the line fittings. Also check around the water filter housing for drips.
Run a paper towel along each water connection — dampness indicates the leak source.
When to Call a Professional
Contact a qualified technician if:
- The defrost drain freezes over again within a week of clearing it
- The leak source is from an internal water line that is not accessible without disassembly
- Water is coming from the base of the compressor or sealed system components
