Daewoo Washer Error Code E2

Overflow error

Daewoo codesDaewoo washer codes

Overflow error — water is supplied continuously due to a defective inlet valve, or the water level sensor (pressure sensor) is faulty while the drain motor does not work.

First step from the service manual

Change the valve inlet; if valve is normal, change the water level sensor (pressure sensor).

What E2 means on a Daewoo washer

The E2 error code on a Daewoo washer indicates an overflow condition, meaning the machine has detected that water is rising beyond the intended fill level. This situation occurs when water continues to enter the drum without stopping, which points to a failure in one of two primary control points: the inlet valve or the water level sensor (also called the pressure sensor). The washer's control board monitors water level through the pressure sensor, and when that sensor fails to signal that the correct water level has been reached, or when the inlet valve stays open regardless of the signal, water accumulates unchecked.

The inlet valve is the most common culprit in E2 errors. A defective inlet valve may fail in the open position, allowing water to flow continuously into the drum even when the control board sends a signal to close it. This is often caused by a failed solenoid coil within the valve, debris preventing the valve seat from sealing, or internal diaphragm damage. In these cases, water will not stop entering the machine regardless of the water level reading.

If the inlet valve tests as functional, attention shifts to the water level sensor. The pressure sensor measures air pressure through a small hose connected to the tub. If this sensor is faulty, it may send an incorrect signal to the control board, causing the board to keep the inlet valve open past the safe fill point. The diagnostic sequence calls for replacing the inlet valve first, then replacing the pressure sensor if the valve proves to be in normal condition. The drain motor not functioning during this fault is noted as part of the overflow symptom profile, not necessarily a separate failure.

Common causes of E2

  1. 01

    Defective inlet valve stuck open

    Part replacement

    The inlet valve solenoid or internal diaphragm has failed, causing the valve to remain open and allow continuous water flow into the tub regardless of control signals. This is the first component to inspect and replace per the diagnostic sequence.

  2. 02

    Faulty water level sensor (pressure sensor)

    Part replacement

    If the pressure sensor fails, it may send an incorrect or absent signal to the control board, causing the board to keep the inlet valve energized past the proper fill level. This is diagnosed after the inlet valve has been confirmed to be working normally.

  3. 03

    Blocked or kinked pressure sensor hose

    Wiring / connection

    The small rubber hose connecting the tub to the pressure sensor can become clogged with detergent residue or kinked, causing the sensor to misread the water level and triggering an overflow condition.

  4. 04

    Debris in the inlet valve seat

    Wiring / connection

    Mineral deposits or sediment from the water supply can lodge in the valve seat and prevent the valve from closing fully, resulting in a slow but continuous trickle of water that eventually triggers the E2 code.

  5. 05

    Control board failure

    Part replacement

    In less common cases, the control board itself may fail to send the correct cutoff signal to the inlet valve, causing it to remain powered even after the correct water level is reached. This is typically considered after the valve and sensor have both been ruled out.

Frequently asked questions about E2

What does E2 mean on a Daewoo washer?
The E2 code on a Daewoo washer means the machine has detected an overflow condition where water continues to fill past the normal level without stopping. This is caused by either a defective inlet valve that stays open, or a faulty water level pressure sensor that incorrectly signals the control board. The diagnostic process starts with inspecting and replacing the inlet valve, then moving to the pressure sensor if the valve is found to be functioning normally.
Can I fix a Daewoo washer E2 error myself?
A technically capable DIYer can address this error by first checking the inlet valve for signs of failure or debris in the valve seat, and replacing it if necessary. If the valve appears normal, the water level pressure sensor and its connecting hose should be inspected next. Replacing either component requires basic hand tools and comfort working with water supply connections and internal washer components.
Is it safe to keep using my washer when E2 is displayed?
No, you should not continue running the washer while the E2 error is active. An overflow condition means water may fill beyond the tub's safe capacity, which can result in water leaking onto the floor and potential damage to the machine or surrounding area. Disconnect the washer from power and shut off the water supply until the fault is diagnosed and repaired.
How much does it cost to repair a Daewoo washer E2 error?
Repair costs vary depending on which component has failed. A replacement inlet valve typically costs between $20 and $60 for the part, while a water level pressure sensor generally ranges from $15 to $50. If you hire a technician, labor charges will add to those part costs and can range from $75 to $150 or more depending on your location and service provider.
Will resetting my Daewoo washer clear the E2 error?
A power reset may temporarily clear the E2 code from the display, but it will not resolve the underlying fault. If the inlet valve is defective or the pressure sensor is faulty, the overflow condition will return as soon as the washer attempts to fill again. The fault must be corrected by repairing or replacing the failed component before the machine will operate reliably.
