Daewoo washing machines use an onboard diagnostic system to detect problems involving water supply, drainage, load balance, motors, sensors, heaters and electronic controls. When the control system detects an abnormal operating condition, the washing cycle may stop and an error code can appear on the display.

Understanding the code can significantly reduce troubleshooting time because it identifies the system that should be inspected first.

However, Daewoo error codes are highly model and platform dependent. This is particularly important with older Daewoo machines. The same or similar-looking code may have a different definition on another model, generation, regional version or OEM-derived platform.

For example, older Daewoo DWD-series service information documents IE as an input/water-supply error, OE as a drainage error, UE as an imbalance error, E2 as overflow, E4 as leakage, E9 as a water-level sensor abnormality and the H-series as temperature/heater faults.

At the same time, newer Daewoo-branded platforms may use an entirely different system. One current Daewoo manual, for example, documents Er 01, Er 02, Er 03 and Er 04 rather than the older IE/OE/E-series structure.

Therefore:

Always verify the complete model number and, ideally, the model-specific user/service manual before replacing components based solely on an error code.

Safety Before Troubleshooting

Before dismantling a washing machine:

Switch the washer off.
Disconnect it from the electrical outlet.
Close the water-supply tap.
Allow heated components and water to cool.
Drain standing water safely before removing hoses or filters.

Do not perform live-voltage testing unless you are qualified to service mains-powered appliances.

A washing machine contains mains voltage, high-current heater circuits, moving components and water in close proximity. Incorrect testing can cause electric shock, flooding or further electronic damage.

Daewoo IE Error – Water Inlet / Input Error

Meaning

On applicable older Daewoo platforms, IE means Input Error or water-supply failure.

For example, DWD-L100-series documentation defines IE as occurring when the designated water level is not reached within the allowed filling period.

Common Causes

Water tap closed
Low household water pressure
Kinked inlet hose
Clogged inlet filter screen
Defective water inlet valve
Loose valve connector
Damaged wiring
Pressure/water-level sensing problem
Control-board problem

Troubleshooting

First confirm that water is available at the tap.

Fully open the supply valve and inspect the inlet hose for crushing or kinks.

Disconnect power and shut off the water before removing the inlet hose. Inspect the small mesh filter at the valve connection.

If it is clogged with sediment, carefully clean it without damaging the screen.

If adequate water reaches the appliance but the valve never opens, inspect the inlet valve and its wiring.

A technician can determine whether the valve coil, control signal or water-level detection circuit is responsible.

Daewoo OE Error – Drainage / Output Error

Meaning

OE commonly means Output Error, indicating that the washer has failed to drain within the expected period.

Older Daewoo service documentation describes OE as occurring when the water level fails to reach the reset point after drainage has been operating for a specified period.

Common Causes

Blocked pump filter
Coin, button or debris in pump
Kinked drain hose
Clogged household drain
Defective drain pump
Loose pump connector
Damaged wiring
Water-level sensor fault
PCB fault

Solution

Check the drain hose first.

Next, clean the pump filter if the model provides an accessible filter.

Be prepared for water to escape when opening the filter housing.

Inspect the pump chamber for foreign objects.

If the pump hums but does not drain, the impeller may be jammed.

If the pump remains completely silent, electrical testing of the pump, wiring and control circuit may be required.

Daewoo UE Error – Unbalanced Load

Meaning

UE normally indicates an unbalanced laundry load.

Daewoo service information describes UE as occurring when the machine repeatedly fails to achieve acceptable balance during spin.

Common Causes

One heavy item being washed alone
Towels collected on one side
Overloaded drum
Very small load
Washer not level
Weak suspension components
Excessive mechanical movement

Solution

Pause the washer and redistribute the clothes evenly.

For a single heavy blanket or towel, add suitable items to improve load distribution if permitted by the machine's instructions.

Check that all feet are firmly contacting the floor.

If UE appears with virtually every load, inspect:

Shock absorbers
Suspension springs
Drum movement
Leveling feet
Balance detection system

Repeated UE errors with correctly balanced loads can indicate a mechanical problem rather than a laundry problem.

Daewoo LE Error

LE requires particularly careful model verification.

Daewoo has produced numerous washer families, and generic internet lists do not always assign LE consistently.

Do not automatically assume that LE means the same thing as an LE code on another manufacturer's washer.

Recommended Procedure

Record:

Full model number
Serial number
Exact displayed code
Point in the cycle where it appears

Then consult the documentation for that specific model.

Daewoo E2 Error – Overflow

Meaning

On documented older Daewoo DWD platforms, E2 indicates an overflow condition.

Service information describes E2 as occurring when the detected water level rises above the overflow threshold, potentially because the water-supply valve continues operating.

Possible Causes

Inlet valve mechanically stuck open
Defective water-level sensor
Blocked pressure hose
Disconnected pressure hose
Wiring problem
PCB/valve-control fault

Troubleshooting

If water continues entering even after the machine is switched off, close the household water tap immediately.

A mechanically stuck inlet valve can allow water to continue entering without electrical power.

If filling stops when power is removed, investigate the control circuit, pressure sensor and associated wiring.

Do not continue operating a washer that repeatedly overfills.

Daewoo E4 Error – Water Leakage

Meaning

On several older Daewoo platforms, E4 indicates water leakage or abnormal loss of water during washing.

DWD-series service information associates E4 with repeated water re-supply caused by the water level falling unexpectedly.

Possible Causes

Leaking drain hose
Loose hose clamp
Tub leak
Door seal leak
Pump housing leak
Detergent dispenser leak
Siphoning through drain hose
Pressure sensing problem

Solution

Disconnect the machine and inspect beneath and behind it.

Look for water around:

Drain pump
Tub-to-pump hose
Drain hose
Inlet connections
Dispenser
Door gasket
Tub seams

Also inspect drain-hose installation. An incorrectly installed hose can sometimes cause unintended siphoning that resembles a leak to the control system.

Daewoo E5 Error – High Voltage / Drive Fault

On certain Daewoo inverter-drive platforms, E5 is associated with excessive DC-link voltage in the motor drive system. Service information describes the drive stopping when the DC-link voltage becomes excessively high.

Other service references also associate E5 troubleshooting with load/motor-drive or PCB-related conditions.

Check

Laundry trapped between drum and gasket
Drum rotates freely
Motor connectors
Harness condition
Supply voltage
Motor-control electronics
Main/inverter PCB

Because this involves high-voltage electronics, component-level diagnosis should normally be performed by a qualified technician.

Daewoo E6 Error – Motor / Excess Current Fault

Meaning

On applicable electronically controlled Daewoo machines, E6 can indicate an abnormal motor-current or drive-system condition.

Some Daewoo diagnostic information describes the error as an EMG/current fault that stops motor operation.

Possible Causes

Drum mechanically jammed
Clothing trapped between drum and gasket
Motor winding fault
Shorted wiring
Loose motor connector
Motor-control PCB failure
Excessive mechanical load

Solution

Disconnect power and rotate the drum manually.

It should rotate without severe binding.

Inspect the motor harness and connectors.

If mechanical resistance is normal, electrical testing of the motor and inverter/control circuitry is required.

Daewoo E7 Error – Motor Direction / Hall Sensor Error

Meaning

E7 is associated with incorrect motor-direction feedback on some Daewoo platforms.

Service information describes it as a condition where Hall-sensor feedback does not correspond with the expected direction of motor rotation.

Possible Causes

Defective Hall sensor
Loose Hall-sensor connector
Motor wiring fault
Defective motor
PCB/inverter fault

Troubleshooting

Inspect all motor connectors.

Look for:

Burnt terminals
Loose pins
Corrosion
Broken wires
Harness damage caused by vibration

If connections are good, test the Hall sensor and motor according to the service specifications for the exact model.

Daewoo E8 Error – Motor / Initial Operation Failure

Meaning

E8 commonly indicates motor operation failure on applicable older Daewoo machines.

Some service documentation describes E8 as abnormal Hall-sensor input during initial motor operation, potentially caused by motor connection problems.

Possible Causes

Motor connector disconnected
Damaged motor wiring
Hall sensor failure
Motor failure
Drum mechanically locked
Excessive load
PCB/inverter failure

Solution

Remove excessive laundry and check that the drum rotates freely.

Inspect motor connections.

If E8 immediately returns with an empty drum, motor, Hall-sensor and drive-electronics testing may be required.

Daewoo E9 Error – Water-Level / Pressure Sensor Fault

Meaning

E9 commonly indicates a water-level sensor or pressure-sensing abnormality.

Daewoo DWD-L100 service information defines E9 using abnormal frequency readings from the water-level sensing system.

Possible Causes

Defective pressure sensor
Pressure hose disconnected
Split pressure hose
Air chamber blocked with detergent residue
Loose sensor connector
Damaged wiring
PCB input fault

Troubleshooting

Inspect the small air-pressure hose running from the tub/air chamber toward the pressure sensor.

Check for:

Cracks
Kinks
Blockages
Loose connections
Water contamination

Do not randomly adjust pressure switches or sensor calibration.

If the hose system is good, test or replace the sensor according to the model's service specifications.

Daewoo H2 Error – Wash Temperature Sensor / Thermistor Fault

Meaning

H2 generally indicates an open, shorted, disconnected or defective wash-temperature sensor.

This is specifically documented in older Daewoo service information.

Possible Causes

Defective thermistor
Disconnected thermistor
Damaged connector
Broken wiring
PCB sensing-circuit fault

Solution

Disconnect power.

Inspect the thermistor connector and wiring.

A technician can measure thermistor resistance and compare it with the temperature/resistance specification for that particular model.

Replace the thermistor if measurements are outside specification.

Daewoo H4 Error – Wash Temperature Overheating

Meaning

H4 indicates an abnormally high wash-temperature reading on applicable models.

For example, one Daewoo service manual defines H4 when the wash-temperature sensor detects approximately 95°C or higher, although thresholds can differ between platforms.

Possible Causes

Defective thermistor
Heater operating without sufficient water
Water-level sensing problem
Heater relay stuck
PCB fault
Wiring problem

Important

Do not repeatedly reset an H4 error.

If the machine is genuinely overheating, continued operation can damage laundry and washer components.

Switch off the washer and investigate the heating and water-level circuits.

Daewoo H6 Error – Wash Heater Failure

Meaning

H6 generally means that the washing heater is not producing the expected temperature increase.

Older service documentation detects the condition when temperature fails to increase sufficiently after the heater has operated for a defined period.

Possible Causes

Open heating element
Heater wiring failure
Burnt connector
Thermistor problem
Heater relay fault
PCB fault
Insufficient water

Troubleshooting

Inspect the heater terminals for overheating or loose connections.

A technician can test:

Heater resistance
Heater insulation to earth
Thermistor resistance
Wiring continuity
Heater relay/control output

A heater that has failed insulation testing should be replaced even if its resistance appears approximately correct.

Daewoo H8 Error – Heater Overheating / Heater Operating Without Water

Meaning

H8 generally indicates abnormal heater temperature rise, often associated with insufficient water around the heater.

Daewoo service information describes H8 as rapid heater-temperature increase associated with lack of water in the tub.

Possible Causes

Insufficient water
Water-level sensor problem
Blocked pressure system
Heater fault
Heater relay problem
Thermistor fault
PCB fault

Solution

Do not simply replace the heater.

First determine why the heater was operating with insufficient water.

Check the:

Water supply
Water level
Pressure hose
Pressure sensor
Thermistor
Heater
Heater-control circuit

H8 can indicate a potentially unsafe heating condition and should be treated seriously.

What About Daewoo E3?

Not every Daewoo platform uses every number in sequence.

Never assume that because E2 and E4 exist, E3 must represent a predictable intermediate fault.

Use the exact model documentation.

Why Daewoo Error Codes Can Differ Between Models

This is particularly important when maintaining a technical knowledgebase.

Daewoo washers have been produced across different generations, markets and control platforms. Diagnostic systems therefore vary.

For example, older DWD documentation uses codes such as:

while a newer Daewoo manual available from Daewoo's website uses:

Er 01 – door not properly closed
Er 02 – low water pressure/level
Er 03 – pump/filter/pump electrical problem
Er 04 – excessive water

This demonstrates why model verification should be considered mandatory rather than optional.

How to Reset a Daewoo Washing Machine Error

For a temporary electronic error, a basic power reset may help.

Press Power to switch off the washer.
Disconnect it from the electrical supply.
Wait several minutes.
Reconnect power.
Select a short cycle.
Observe whether the error returns.

Some older Daewoo service documentation specifically notes that certain diagnostic displays clear after power is turned off and on.

However, resetting does not repair the underlying fault.

If the code returns, troubleshoot the corresponding system.

Diagnostic Strategy for Technicians

Instead of immediately replacing the component named by an error code, use a systematic approach.

Step 1 – Record the Code

Write down the exact code before resetting the machine.

IE and E1, for example, should not automatically be treated as identical.

Step 2 – Record the Model Number

Model-specific documentation is essential.

Step 3 – Determine When the Error Occurs

During filling

Investigate:

Water pressure
Inlet valve
Pressure sensor
IE/E2/E9-related systems

During draining

Investigate:

Pump filter
Drain pump
Drain hose
OE-related systems

During spin

Investigate:

Load balance
Motor
Hall sensor
Suspension
UE/E6/E7/E8 systems

During heating

Investigate:

Heater
Thermistor
Water level
H2/H4/H6/H8 systems

This approach can dramatically narrow the fault.

Component-Level Troubleshooting

Water Inlet Valve

Inspect for:

Blocked inlet screens
Coil failure
Mechanical sticking
Damaged connectors

A valve that allows water through when electrically de-energized is mechanically defective and should normally be replaced.

Drain Pump

Check for:

Foreign objects
Broken impeller
Winding failure
Intermittent operation
Burnt connectors

Pressure Sensor

Check the entire pressure system rather than replacing the sensor immediately.

A blocked air chamber or leaking pressure hose can generate misleading readings.

Motor and Hall Sensor

Inspect connectors carefully because vibration can create intermittent motor feedback faults.

Heater

Check heater resistance and insulation.

Earth leakage from a heater can cause electrical protection devices to trip even when the heater still produces heat.

Thermistor

Thermistors normally change resistance as temperature changes.

Use the exact model's resistance-temperature specification when evaluating the sensor.

PCB

The control board should generally be considered after external components, wiring and sensors have been verified.

Replacing the PCB first can be expensive and may not solve the original fault.

When Should You Call a Technician?

Professional service is recommended when:

E2 overflow repeatedly occurs
Water continues entering with the washer powered off
E5/E6/E7/E8 repeatedly appear
H4 or H8 indicates overheating
The circuit breaker/RCD trips
There is a burning smell
Wiring or connectors are burnt
Water has reached electronic components
PCB diagnosis is required
Motor/inverter testing is required
Heater insulation testing is required

Immediately disconnect the washer if you see smoke, electrical arcing or significant uncontrolled water leakage.

Frequently Asked Questions (FAQ)

1. What does IE mean on a Daewoo washing machine?

On many older Daewoo platforms, IE indicates a water-inlet or input error. Check the water tap, pressure, inlet hose, filter screen, inlet valve and related wiring.

2. How do I fix Daewoo OE?

OE normally indicates that the machine cannot drain properly. Clean the drain filter, inspect the drain hose and check the drain pump.

3. Why does my Daewoo washer show UE?

On documented older Daewoo DWD platforms, E2 means overflow. Check the inlet valve and water-level sensing system.

5. Is Daewoo E4 a leakage error?

On several older platforms, yes. E4 is associated with unexpected water loss or leakage during washing.

6. What causes Daewoo E6?

On applicable motor-drive platforms, E6 is associated with abnormal motor current/drive conditions. Check for a jammed drum, motor problems, wiring faults and drive-electronics problems.

7. What is Daewoo E7?

E7 can indicate incorrect motor-direction feedback. The Hall sensor, motor wiring, motor and PCB should be investigated.

8. What does Daewoo E8 mean?

E8 commonly indicates that the motor has failed to operate correctly or that abnormal motor/Hall feedback has been detected.

9. What does Daewoo E9 mean?

E9 commonly indicates a water-level or pressure-sensor problem.

10. What does H2 mean on a Daewoo washing machine?

H2 commonly indicates a wash-temperature sensor/thermistor fault, such as an open circuit, short circuit or disconnected sensor.

11. What is Daewoo H4?

H4 indicates an overheating or abnormally high wash-temperature condition on applicable models.

12. What causes Daewoo H6?

H6 generally means that the wash heater has failed to raise the water temperature as expected.

13. Is H8 dangerous?

Potentially. H8 can indicate excessive heater temperature caused by insufficient water around the heater. Stop using the washer until the cause is identified.

14. Can I reset a Daewoo error by unplugging the washer?

A power cycle may clear the displayed error, but it does not repair a genuine mechanical, electrical or sensor fault.

15. Why does an error return immediately after resetting?

The control system is detecting the same abnormal condition again. Troubleshoot the underlying system instead of repeatedly resetting the appliance.

16. Should I replace the PCB when an error appears?

Not automatically. Check sensors, wiring, connectors, pumps, valves, heaters and motors before condemning the PCB.

17. Can low water pressure cause an IE error?

Yes. If the washer cannot reach the required water level within its programmed filling time, insufficient water pressure can trigger a fill error.

18. Can excessive detergent cause drainage problems?

Yes. Excessive foam can interfere with drainage and spinning and may contribute to pump/filter-related problems.

19. Are all Daewoo washing-machine error codes universal?

No. They can vary significantly between models and generations.

20. Why is the model number important?

Because the same code may have different definitions, diagnostic thresholds or repair procedures on different Daewoo platforms.

21. Where can I find my Daewoo washer model number?

Look for the product-rating label, commonly located around the door opening, rear panel or another manufacturer-specified identification area.

22. Can a blocked pressure hose cause E9?

Yes. The sensor may be functional while a blocked, leaking or disconnected pressure hose prevents it from correctly detecting water level.

23. Can a faulty inlet valve cause E2?

Yes. A mechanically stuck valve can continue admitting water and cause an overflow condition.

24. Why does my Daewoo washer display UE only with blankets?

Large items can collect on one side of the drum during spin, producing severe imbalance.

25. Can I continue using the washer with an H-series error?

Repeated H-series temperature or heater errors should be investigated before further use, particularly overheating-related H4 or H8 faults.

Final Technical Notes

Daewoo washing-machine error codes provide an excellent starting point for diagnosis, but they should never be treated as automatic instructions to replace a particular component.

The most useful diagnostic sequence is:

Error code → exact model verification → operating stage → visual inspection → wiring/connectors → component testing → PCB diagnosis.

For older Daewoo platforms, the commonly encountered IE, OE, UE, E2, E4, E5, E6, E7, E8, E9, H2, H4, H6 and H8 families can help identify water-supply, drainage, balance, motor, pressure-sensing and heating faults. Service documentation confirms many of these definitions while also showing that thresholds and diagnostic logic can differ between models.

For newer machines, do not assume the same code set applies. Daewoo's own newer documentation demonstrates that some models instead use an Er 01–Er 04 diagnostic system.

Technical Disclaimer: This information is intended for troubleshooting and educational purposes. Error-code meanings, component specifications, wiring arrangements and diagnostic procedures can vary by Daewoo model, production generation and market. Always verify the exact model's official documentation before replacing components. Electrical, heater, motor, inverter and PCB repairs should be performed by appropriately qualified personnel.
