4E5 error code
Insufficient water pressure or flow
What does Samsung Dishwasher 4E5 mean?
The dishwasher cannot fill with adequate water pressure or flow. Samsung uses 4E5 to identify a water-supply or water-level condition on the affected dishwasher. 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 4E5 error code indicates the dishwasher cannot fill with adequate water pressure or flow. Samsung uses 4E5 to identify a water-supply or water-level condition on the affected dishwasher. 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 dishwasher displays 4E5 and may interrupt its wash or drain programme.
- The programme may pause, fail to fill, wash poorly or leave water in the tub.
- Pumps or valves may run differently from a normal programme.
- The code may return at the same stage of each cycle.
- The precise behaviour can vary by model, software version and the point at which 4E5 is detected.
Common causes
- Samsung Dishwasher 4E5 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 4E5, the model number and what the dishwasher 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 4E5 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 4E5 reappears, note when it happens and give that information to the service engineer.
Reset instructions
End the programme only when it is safe to do so. Complete the relevant external checks, then use the model-specific cancellation or power-reset procedure once. A code that returns on the next programme needs further diagnosis. A reset can clear the display without correcting the cause, so confirm normal operation afterwards and retain a record of 4E5 for the engineer.

DishwasherModel and region dependentWhen to contact a professional
Contact Samsung or an authorised service provider if 4E5 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 4E5 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.
