4E error code
Water supply issue
What does Samsung Dishwasher 4E mean?
Water supply issue. Samsung uses 4E to identify a water-supply or water-level condition on the affected washing machine. The code is a diagnostic starting point rather than proof that one specific part has failed. Confirm the complete code, exact model number and region before using repair information or ordering components.
The code identifies the condition detected by the product; it does not always identify the failed component on its own. Confirm the full code and exact model before ordering parts or attempting a reset.
The Samsung Dishwasher 4E error code indicates water supply issue. Samsung uses 4E to identify a water-supply or water-level condition on the affected washing machine. The code is a diagnostic starting point rather than proof that one specific part has failed. Confirm the complete code, exact model number and region before using repair information or ordering components. This guide explains what the code means, the symptoms and likely causes, the checks that are safe to make, and when to stop and arrange an authorised repair.
Symptoms you may notice
- The washing machine displays 4E and may interrupt its wash or rinse cycle.
- The cycle may pause before filling, washing, spinning or draining.
- The remaining-time display may stop changing while the code is active.
- Water level, drum movement or door operation may differ from normal.
- The precise behaviour can vary by model, software version and the point at which 4E is detected.
Common causes
- Samsung Washing machine 4E is associated with the water-supply or water-level condition described in Samsung's guidance.
- The water supply may be restricted, interrupted or below the pressure expected by the appliance.
- An inlet hose, filter, valve or accessible connection may be obstructed or incorrectly positioned.
- The appliance may be receiving an incorrect signal from its water-level or flow-monitoring system.
- Internal wiring, a sensor or a control component may require diagnosis.
- The display code alone cannot confirm which cause applies; diagnosis should begin with the least invasive documented checks.
Before you start troubleshooting
Use the display, rating label or product menu to confirm the exact model. Similar-looking codes can have different meanings across product generations and regions.
- Record the complete code and the point in the cycle when it appeared.
- Check accessible water, drain, door and filter areas only when the appliance is safely isolated.
- Stop if there is leaking water, a burning smell or a repeatedly tripping electrical supply.
Troubleshooting steps
- Photograph or write down 4E, the model number and what the washing machine was doing when the code appeared.
- Read the Samsung guidance linked in the source field and check that it applies to the exact model and region.
- Confirm that the water supply is available and that any user-operated tap is fully open.
- Inspect accessible hoses for sharp bends, crushing or freezing without removing appliance panels.
- Clean only user-accessible inlet filters when the exact model instructions describe the procedure.
- Restart once after restoring the supply, then monitor the next cycle.
- If 4E returns, stop repeating resets and arrange authorised diagnosis with the recorded details.
Can you fix this error code yourself?
The safest next step depends on the exact model and the cause behind the code. External checks may help, but a returning fault needs professional diagnosis.
A successful reset is not proof that the underlying issue is fixed. If 4E reappears, note when it happens and give that information to the service engineer.
Reset instructions
Cancel the cycle only if the controls respond normally. After completing the documented external checks, disconnect power for the period stated in the exact Samsung model manual, reconnect it and run one short test cycle. Do not repeatedly reset a returning code. A reset can clear the display without correcting the cause, so confirm normal operation afterwards and retain a record of 4E for the engineer.
Applicable products and models
When to contact a professional
Contact Samsung or an authorised service provider if 4E returns after the documented external checks, appears with leakage, smoke, overheating, electrical tripping, unusual noise or loss of a safety-critical function. Professional diagnosis is also required whenever testing would involve internal wiring, refrigerant, gas, high-voltage, sealed-system or moving components. Provide the full code, model number, serial details, region and the stage of operation at which the fault occurs.

Can I fix Samsung Dishwasher 4E myself?
Some external checks may be suitable for the user, but the result depends on the exact model and cause. Use the official manual and arrange service if the code returns.
Should I reset the product after code 4E?

Do not repeatedly reset a returning code. A reset can clear the display without correcting the cause, so confirm normal operation afterwards and retain a record of 4E for the engineer.
