Answer to continue safely
Is it safe to keep using?
Maybe.
Can I reset the code?
Yes.
When to stop immediately?
Stop if you notice: Water is leaking from behind the refrigerator or from the supply line connection, You hear the inlet valve buzzing continuously without stopping.
Symptoms You May Notice
Ice tray fills with little or no water
The ice maker attempts a fill cycle but the tray remains empty or only partially filled, resulting in thin or missing ice cubes.
33E code on refrigerator display
The control panel shows 33E, indicating the ice maker water fill cycle failed to deliver the expected volume.
Small or hollow ice cubes
Reduced water flow produces undersized ice cubes that are thin, crescent-shaped, or hollow in the center.
Ice maker cycles but produces no ice
The harvest mechanism runs on schedule but ejects nothing because the tray never received enough water to freeze.
Possible Causes
Frozen water supply line
The narrow water tube running through the freezer compartment or door hinge freezes solid, blocking water flow to the ice maker tray while the door dispenser may still work via a separate line.
DIY PossibleFailed ice maker inlet valve
The dedicated solenoid valve that controls water flow specifically to the ice maker can fail electrically, preventing it from opening when the control board commands a fill.
Requires ProfessionalLow household water pressure
Water pressure below 20 psi at the refrigerator connection cannot push adequate volume through the inlet valve and narrow supply tube within the timed fill window.
DIY PossibleSafe Checks You Can Do
-
1
Verify water supply
Check that the water shutoff valve behind the refrigerator is fully open. Test the door water dispenser — if water flows normally from the dispenser, the household supply is fine and the issue is specific to the ice maker line.
If the dispenser also has weak flow, the problem is the main supply or filter. Replace the water filter if it has not been changed in 6 months.

Thaw a frozen supply line
Raise the freezer temperature setting to 5 degrees Fahrenheit and leave the freezer door slightly ajar for 2 hours with towels on the floor to catch drips. Alternatively, use a hair dryer on low heat along the back wall of the freezer where the water line runs.
Samsung recommends keeping the freezer at 0 degrees Fahrenheit — if the supply line freezes frequently at this setting, a technician should check the line routing.

Reset and test
After addressing the supply issue, press the ice maker test button to force a fill and harvest cycle. Listen for water flowing into the tray — a soft gurgling sound lasting 5 to 8 seconds indicates a normal fill.
If you hear the valve click open but no water flows, the inlet valve itself has likely failed.
When to Call a Professional
Contact a qualified technician if:
- The door water dispenser works fine but the ice maker never fills
- 33E persists after thawing the supply line and verifying water pressure
- The inlet valve clicks but no water reaches the ice tray
