Samsung Washer Error Code OE

A fault is detected in the water level sensor

Samsung codesSamsung washer codes

A fault is detected in the water level sensor. Data (frequency) shows the water level is at or above the overflow water level. The machine will automatically start draining water until the water level falls below the reset water level.

First step from the service manual

First check to see that all water valves are not stuck. If water valves are OK, check water level.

What OE means on a Samsung washer

The OE error code on a Samsung washer indicates a fault detected by the water level sensor (pressure sensor). Specifically, the sensor's frequency output is reading at or above the threshold programmed as the overflow water level. When this condition is detected, the washer's control board interprets it as a dangerously high water level and automatically initiates a drain cycle, continuing to pump water out until the sensor frequency drops back below the reset water level threshold. This is a protective function designed to prevent water overflow and potential flooding.

The water level sensor works by measuring air pressure in a sealed chamber connected to the tub. As water rises, it compresses the air in the chamber, and the sensor translates that pressure into a frequency signal read by the control board. If the sensor is faulty, the air trap hose is blocked or kinked, or water genuinely is overfilling due to a stuck-open inlet valve, the control board will receive an abnormal frequency reading and trigger OE. The first diagnostic priority is confirming whether the water level is actually too high or whether the sensor is falsely reporting an overflow condition.

A stuck or continuously running water inlet valve is the most mechanically dangerous cause, as it allows water to keep entering the tub regardless of the control board's commands. A defective pressure sensor or a damaged, disconnected, or clogged air trap hose can produce the same error code without any actual overfill. Checking the inlet valves first, as directed, rules out an active flooding risk before moving on to sensor and hose inspection.

Common causes of OE

  1. 01

    Stuck open water inlet valve

    Part replacement

    If a water inlet valve fails in the open position, water continuously enters the tub even when the machine is not calling for it, causing a genuine overfill condition. Check whether water is flowing into the drum when the machine is off or idle.

  2. 02

    Faulty water level pressure sensor

    Part replacement

    A defective pressure sensor can send an incorrect frequency signal to the control board, triggering OE even when the actual water level is normal. If the inlet valves are functioning correctly and no overfill is visible, the sensor itself is the next suspect.

  3. 03

    Blocked, kinked, or disconnected air trap hose

    Wiring / connection

    The pressure sensor relies on a small hose connecting it to the tub air chamber. If this hose is kinked, clogged with debris or detergent residue, or has come loose, the sensor will receive an inaccurate pressure reading and can falsely report an overflow level.

  4. 04

    Excess detergent causing suds buildup

    Wiring / connection

    Using too much detergent or non-HE detergent in an HE washer creates heavy sudsing that the pressure sensor can interpret as a high water level. Running a drum-clean or rinse cycle without detergent can confirm if suds are the issue.

  5. 05

    Control board fault

    Part replacement

    If the inlet valves, pressure sensor, and air trap hose all test within normal parameters, a failing control board may be misreading the sensor's frequency signal and incorrectly triggering the OE code.

Frequently asked questions about OE

What does OE mean on a Samsung washer?
OE on a Samsung washer indicates that the water level sensor has detected a water level at or above the programmed overflow threshold. The machine responds by automatically draining water until the level drops below the reset point. The fault can stem from a genuine overfill caused by a stuck inlet valve or from a sensor or hose problem that causes a false reading. Checking that the water inlet valves are not stuck open is the recommended first diagnostic step.
Can I fix the OE error code myself?
Some causes of OE are DIY-friendly. You can inspect the air trap hose for kinks or blockages, check that the hose connections to the pressure sensor and tub are secure, and run a cycle with no detergent to rule out suds buildup. If a water inlet valve is stuck open or the pressure sensor itself is defective, those parts will need to be replaced, which is within reach of a confident DIYer who is comfortable working with water supply connections and basic electrical connectors.
Is it safe to keep using my washer when it shows OE?
You should not continue running the washer until the cause is identified, especially if a stuck inlet valve may be involved. A valve that cannot close will keep adding water to the tub and could eventually lead to overflow and water damage. The machine does automatically start draining when OE appears, but that protective function is not a permanent fix for an underlying overfill problem.
Will resetting my Samsung washer clear the OE error?
Unplugging the washer for a few minutes or pressing the power button to reset it may temporarily clear the OE code, but the error will return if the underlying cause is not addressed. If the inlet valve is stuck, the pressure sensor is faulty, or the air trap hose is blocked, the same fault condition will simply trigger the code again on the next cycle. A reset is useful for confirming whether the error is intermittent, but it is not a repair.
How much does it cost to repair the OE error on a Samsung washer?
Repair costs depend on which component is at fault. A water inlet valve typically ranges from $25 to $75 for the part, while a water level pressure sensor usually falls in the $20 to $60 range. If professional labor is involved, total repair costs including parts and labor generally run between $100 and $250 depending on your location and the specific parts needed. Clearing a blocked air trap hose costs nothing beyond your time.
