Daewoo Washer Error Code IE

Water inlet error

Daewoo codesDaewoo washer codes

Water inlet error — water is not entering the washing machine due to closed tap, clogged valve inlet filter, defective valve inlet, defective water level sensor, drain motor running during water supply, or PCB ASS'Y not detecting water level.

What IE means on a Daewoo washer

The IE error code on a Daewoo washer indicates a water inlet error, meaning the machine is not detecting a sufficient water supply within the expected fill time. The water inlet system involves several components working together: the water supply tap, the inlet valve (a solenoid-controlled valve that opens to allow water flow), a fine mesh filter screen at the valve inlet connection, and a water level pressure sensor (also called a pressure switch) that signals the PCB ASS'Y when the tub has reached the target water level. If any part of this chain fails or is disrupted, the control board cannot confirm that water has entered the drum and triggers the IE code.

The most frequent causes are external and easy to resolve without parts. A closed or partially open water tap is the first thing to check, followed by a clogged inlet filter screen. The filter sits where the water supply hose connects to the inlet valve and collects mineral deposits and debris over time. A blocked filter restricts flow to the point where the tub fills too slowly or not at all. If the tap is open and the filter is clean, the inlet valve solenoid itself may have failed and will not open when energized by the PCB.

Beyond the valve, a defective water level sensor can cause the IE code even when water is entering normally. If the pressure sensor fails or its air hose becomes disconnected or cracked, it cannot relay water level information to the PCB ASS'Y, and the board treats the situation as a no-fill condition. Additionally, if the drain motor activates during the fill cycle, it will pump out incoming water and prevent the tub from reaching the required level, resulting in the same error.

Common causes of IE

  1. 01

    Closed or restricted water supply tap

    Wiring / connection

    If the tap supplying the washer is closed, partially open, or has low water pressure, the machine cannot fill. Open the tap fully and confirm household water pressure is adequate.

  2. 02

    Clogged inlet valve filter screen

    Wiring / connection

    A fine mesh filter sits at the point where the water supply hose connects to the inlet valve. Sediment and mineral buildup can block this screen and severely restrict flow. Remove the hose, inspect the filter, and clean it with a brush under running water.

  3. 03

    Defective water inlet valve

    Part replacement

    The solenoid-operated inlet valve controls water flow into the tub. If the solenoid coil has failed or the valve is mechanically stuck closed, water will not enter even with a clean filter and open tap. A failed inlet valve requires replacement.

  4. 04

    Defective water level sensor

    Part replacement

    The water level pressure sensor monitors how much water is in the tub and signals the PCB ASS'Y. If the sensor is faulty, its air hose is disconnected, or the hose is cracked, the control board will not detect water even if the tub is filling correctly, triggering the IE code.

  5. 05

    Drain motor activating during fill cycle

    Part replacement

    If the drain motor runs while the machine is trying to fill, incoming water is pumped out as fast as it enters and the tub never reaches the required level. This can indicate a PCB ASS'Y fault or a stuck drain valve, and typically requires component-level diagnosis.

Frequently asked questions about IE

What does IE mean on a Daewoo washer?
IE stands for water inlet error on a Daewoo washer. It means the machine started a fill cycle but did not detect enough water entering the tub within the expected time. The cause can range from a simple closed water tap or clogged inlet filter to a failed inlet valve, a defective water level sensor, or a PCB ASS'Y that is not correctly reading the water level.
How do I fix the IE error on my Daewoo washer?
Start by confirming the water supply tap is fully open and that household water pressure is normal. Next, disconnect the water supply hose from the back of the machine and inspect the small filter screen at the inlet valve connection, cleaning any debris or mineral buildup with a brush. If those steps do not resolve the error, the inlet valve solenoid, the water level pressure sensor, or the PCB ASS'Y may need to be tested and potentially replaced.
Is it safe to keep using my Daewoo washer when the IE code is showing?
The IE error causes the machine to stop the cycle because it cannot confirm a safe water level in the tub. Running a wash cycle without a proper water supply can stress the motor and pump. It is best to resolve the underlying cause before running additional cycles to avoid further damage to the appliance.
How much does it cost to repair a Daewoo washer IE error?
If the issue is a closed tap or a clogged filter screen, there is no parts cost at all. If the inlet valve needs replacement, parts typically range from $20 to $60 depending on the model, plus labor if a technician is used. A faulty water level sensor is generally in a similar price range, while a PCB ASS'Y replacement can cost significantly more, often $80 to $200 or higher for parts alone.
Will resetting my Daewoo washer clear the IE error code?
Resetting the machine by unplugging it for a few minutes may temporarily clear the IE code, but the error will return at the next fill cycle if the underlying problem has not been fixed. A reset is useful for ruling out a one-time electronic glitch, but it is not a repair. Persistent IE errors require physical inspection of the water supply, inlet filter, inlet valve, and water level sensor.
