Samsung dishwasher 4C / 4E error
Error4C / 4E
Samsung identifies 4C and 4E as water-supply errors. Check the supply shut-off, temperature, pressure, and visible hose path before service.
What the code means
The dishwasher is not receiving water at the required pressure or temperature
Close the water shut-off before moving or disconnecting a supply line. Stop immediately if a connection leaks; do not work on live electrical parts.
Typical symptoms
014C or 4E appears during filling
02The dishwasher does not receive enough water to start or continue
03A kinked supply line or unsuitable household supply may be present
Likely causes
Start with the least invasive explanation and stop if the check requires internal electrical or sealed-system access.
01The water supply is closed or restricted
02Supply pressure or temperature is outside Samsung's stated range
03A visible supply line or connection problem
Safe next steps
- 1Turn the dishwasher off and close the water shut-off before touching the supply path
- 2Confirm the shut-off valve is fully open
- 3Inspect the visible supply line for kinks, crushing, or leaks
- 4Check that hot-water supply is within Samsung's stated 120–149°F range and household pressure is 20–120 psi when those checks are safely available
- 5Restore the supply and run one short fill test; request service if 4C/4E returns
Step-by-step repair
- 1Open the shut-off valve, correct only a visible hose restriction, and stop if the supply line or connection leaks. Do not select an inlet valve or internal part from 4C/4E alone; use Samsung service if the household supply is suitable and the code returns.
