What the code means
The dishwasher cannot confirm acceptable incoming water supply conditions in Samsung’s official support scope.
Confirmed: Samsung documents 4C and 4E on dishwashers as water-supply errors where the dishwasher is not getting water at the required pressure or temperature.
Can you keep using it?
Only after safe supply checks and only if the code clears.
When to stop
Stop if the appliance leaks, water supply access is unsafe, or the unit must be pulled out to inspect it.
When to call a professional
Request service if 4C or 4E continues after accessible water-supply checks.
Safe checks
- Confirm the code is 4C or 4E.
- Check the household water supply valve if it is accessible.
- Look for obvious inlet hose kinks or shutoff without moving the built-in appliance unsafely.
Confirmed by the manufacturer
- The dishwasher is not getting water at the pressure or temperature it needs.
- Samsung points this code group to dishwasher water supply requirements.
Commonly associated with this fault
- A closed supply valve or restricted inlet path can fit the official water-supply explanation.
Not confirmed for this exact model
- A failed inlet valve, flow sensor, control, or wiring fault is not confirmed by 4C or 4E alone.
Reset instructions
No reset procedure is published here because the current source does not document one for this scope.
Do not repeatedly restart if water supply appears normal but the code returns.
Information to collect before calling service
