Error codeE4 / E1
ApplianceWasher
Quick answer
E4 is the current water supply error on Samsung washers, with E1 as the legacy code; older washers use E4 for unbalanced load.
Model compatibility: Samsung reuses codes across series and model years, so E4 / E1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Water supply error: no water filling detected; legacy E4 is an unbalanced load.
E4, or E1 on older units, is a water supply error: the washer does not detect that it is filling with water. E1 is the legacy code. Current and legacy codes are listed together, and meanings may differ by model.
Water supply checks
Confirm the tap is on and that water pressure is between 0.5 and 8 bar.
Check that the hoses are not kinked.
Check the inlet filters inside the end of the water valve.
If the water supply is fine, contact support.
Legacy E4: unbalanced load
On a legacy series E4 stands for UE, an unbalanced load. The spin stops for safety and it is not a fault. Redistribute the laundry. For a single large or heavy item, add 2 or 3 towels and spin again.
If the supply is fine and the code stays, call (310) 896-4231 for Samsung washer service in Los Angeles, or read washer repair. Say which checks you did and give the model number.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
