What does the Samsung 4C / 4E error code mean?
The 4C (or 4E) code indicates that the dishwasher is not detecting sufficient water entering the machine. The fill cycle timed out before reaching the required water level. This is typically an external water supply issue rather than a machine fault.
🔍 Symptoms
- Machine starts a cycle but stops almost immediately
- No sound of water entering at the beginning of a programme
- Wash cycle completes quickly but dishes are completely unwashed
- Machine display shows 4C or 4E within minutes of starting
- The inlet valve can be heard clicking but no water flows
How to fix the Samsung 4C / 4E error code
- Check that the water supply tap behind or under the machine is fully open. On Samsung models, this is often a push-button tap that can be accidentally knocked to the off position.
- Check the inlet hose for kinks. Samsung’s inlet hoses often have an integrated Aquastop safety device — if this has been triggered by a water surge, you may need to reset it or replace the hose.
- Unscrew the inlet hose from the back of the machine and clean the mesh filter inside the machine’s connection point.
- Check your water pressure. Samsung dishwashers typically require a minimum of 0.5 bar. Run a kitchen tap simultaneously — if pressure drops significantly, this may be the issue.
- If all external checks pass, test the inlet solenoid valve with a multimeter for continuity. A faulty valve will need replacing.
Frequently Asked Questions (FAQ)
Q: Can the Samsung Aquastop hose cause 4C errors?
A: Yes. The Aquastop hose contains a solenoid that can fail or be triggered. If the hose is blocked or has activated its safety cut-off, no water will reach the machine.
Q: Is 4C different from 4E on a Samsung dishwasher?
A: They are the same fault. Samsung uses 4C and 4E interchangeably depending on the model — both indicate a water supply timeout error.
Q: I just had the water turned off for work on the street and now I have a 4C error — is this related?
A: Very likely. Air can enter the pipes after a water shutoff. Run your kitchen tap until the flow is steady, then restart the dishwasher.
