What does this error code mean?
Samsung dishwasher error code 4C, also shown as 4E on some models, usually indicates a water supply problem. The dishwasher may start with a brief drain but then stop because little or no fresh water enters.
Check the tap, supply interruption, inlet hose route, and any accessible inlet filter. Stop if the code returns after these checks.
4C relates to the fill path: supply tap, inlet hose, inlet filter, water pressure, inlet valve, and water-level detection.
Symptoms users may notice
- The tub may remain dry after the cycle starts.
- The dishwasher may stop early after a brief drain.
- You may hear little or no water entering.
Why is this happening?
- Water supply valve closed
- Water supply interrupted or low pressure
- Frozen, kinked, or blocked inlet hose
- Blocked inlet filter or faulty inlet valve
What this usually points to
4C relates to the fill path: supply tap, inlet hose, inlet filter, water pressure, inlet valve, and water-level detection.
How to fix this safely
- Switch off and disconnect power before checking accessible hoses.
- Check the water tap is fully open and the hose is not kinked.
- Confirm the household water supply is running normally.
- Try one short programme after refitting everything securely.
Can I fix this myself?
YesYou can check the tap, hose route, and external water supply. Repeated fill faults need diagnosis.
Safety boundary: Disconnect power before accessible checks. Turn off the water before disconnecting an inlet hose.
What not to do
- Do not keep restarting if the tap is closed or water is unavailable.
- Do not force frozen or brittle hoses.
- Do not remove panels to inspect the inlet valve.
Reset steps
- Turn the dishwasher off after completing safe supply checks.
- Wait a few minutes, reconnect power, and try one short programme.
- Stop if 4C returns or no water enters.
Intermittent vs persistent faults
A one-off 4C may clear after restoring supply, but repeated 4C needs diagnosis.
When to call an engineer
Call an appliance engineer if 4C returns after water supply and hose checks, or if inlet valve, sensor, or control diagnosis may be needed.
Safety warning
Disconnect the dishwasher from power before checking accessible hoses, and turn off the water supply before loosening any inlet connection.
