Quick answer: On a Samsung Washer, the 1E error code (also displayed as 1C or iE on some models) indicates a problem with the water level sensor, also called the pressure switch. Samsung Washer 1E means the machine cannot accurately detect how much water is in the drum, causing it to stop the cycle as a safety measure. In many cases you can fix Samsung Washer 1E by clearing the pressure sensor hose of blockages or kinks, running a power reset, and cleaning the machine. If the error persists, the water level sensor itself may need replacement.
The Samsung Washer 1E error code is a water level sensing fault. Every Samsung Washer uses a pressure switch (also called a water level sensor or pressure transducer) to determine how full the drum is. Water entering the tub compresses air in a small chamber connected to the sensor by a rubber hose. The sensor converts air pressure into an electrical signal that tells the control board when to stop filling, when enough water is present for washing, and when the drum is empty after draining.
When the Samsung Washer shows 1E, the control board is receiving an abnormal signal from this sensor. The machine stops to avoid overfilling, underfilling, or running a wash cycle without the right amount of water.
The small rubber hose that runs between the drum tub and the pressure sensor can become kinked during installation or servicing, or can develop internal blockages from detergent residue or mold. A blocked hose sends an incorrect air pressure signal, triggering Samsung Washer 1E.
If the pressure hose develops a crack or comes loose from one of its connection points, air pressure escapes and the sensor cannot read the water level accurately. The Samsung Washer will display 1E because the sensor reading is outside its expected range.
If the pressure switch itself has failed electrically — damaged diaphragm, open circuit in the sensor coil — the Samsung Washer will not be able to determine water level and will stop with 1E. A failed sensor requires replacement.
Vibration and movement over time can loosen the electrical connector to the pressure switch. A loose or corroded connector will cause intermittent 1E errors on the Samsung Washer, especially near the beginning of a fill cycle.
If the control board is not processing the sensor signal correctly, it may report a 1E error even when the sensor and hose are in perfect condition. This is less common but possible, especially on older Samsung Washer models.
Follow the steps below one at a time — many error codes can be fixed faster than they look.
Unplug the Samsung Washer for 5 minutes. This clears any temporary logic fault from the control board that may have caused a false 1E reading. Plug back in and run a cycle. If 1E does not return, the fault was transient.
With the Samsung Washer unplugged, remove the top panel or back panel as needed to access the interior. Find the thin rubber or plastic hose (typically 6–10mm diameter) that runs from the lower tub area up to a small round sensor component. Trace the full length of the hose looking for:
Gently blow air through the hose from one end to check for blockage. If airflow is restricted, try clearing the hose with warm water. If the hose is cracked or severely clogged, replace it. Pressure hose replacements for Samsung Washer models are widely available and inexpensive.
Disconnect the electrical connector to the pressure switch, inspect the pins for corrosion or bending, and reconnect firmly. Connectors on Samsung Washer components should click into place. A loose connector can cause the 1E code to appear and disappear unpredictably.
If the hose is clear and connected but Samsung Washer 1E persists, the pressure switch should be tested. With a multimeter, check the resistance across the switch terminals. Compare the reading to your model’s service specification. If the switch is out of range or shows no continuity, replace it. Pressure switch replacements are a standard Samsung Washer repair.
If all sensor and hose components check out correctly and the Samsung Washer continues to show 1E, have the main control board evaluated by a qualified technician. Board-level faults are difficult to diagnose without specialized equipment.
Yes. Samsung Washer 1E, 1C, and iE all refer to the same water level sensor fault. The display varies by model. The diagnosis and repair are identical for all versions of this code.
The Samsung Washer will stop filling and display 1E when a sensor problem is detected, which is designed to prevent overflow. However, if the sensor is stuck in a “drum empty” state rather than a “fault” state, overfilling is theoretically possible. The 1E stop is a safety response to an abnormal reading.
For an experienced technician, replacing a Samsung Washer pressure switch typically takes 30–60 minutes. DIY replacement is possible if you are comfortable accessing internal components and working with electrical connectors.
Samsung Washer 1E is a water level sensor fault that stops the machine from filling or operating normally. Start with a power reset, then inspect the pressure hose for kinks, cracks, or blockage. Check the sensor connector and reseat it firmly. If 1E persists, test and replace the pressure switch. A clean, intact hose and a functioning sensor are all that is needed to resolve most Samsung Washer 1E errors.
