- Check for a visible kink or blockage in the inlet hose.
- Confirm household water service is not interrupted.
Applicability

Samsung's cited 4C/4E guidance is regional; confirm the local model manual before any hose, screen, or service access.
Reset or retry steps

When to call a technician
- Call Samsung service if the code continues after water-supply checks.
- Call service for suspected inlet valve or sensor faults.

Can I keep using it?
Stop normal use when water is visible or a leak warning is active. Stay clear if water could reach wiring or controls.
- Safe next step
- Follow the code-specific shutdown or protective-drain instructions, turn off water when appropriate, and avoid repeated resets. Do not interrupt a documented protective-drain sequence just to clear the display.
- Stop when
- Water is near wiring, cabinetry is getting wet, the leak returns, or the source is not safely visible.
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Stop and address visible water before retrying the appliance.
- Disconnect power before any service-access step.
- Turn off water before disconnecting any hose.
Do not do this
- Do not continue normal cycles while this code is active; any protective-drain sequence must follow the exact model instructions.
- Do not disconnect inlet hoses until the water supply is off.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Water supply valve not fully open
- Water supply interruption
- Blocked or restricted inlet hose
