SAMSUNG · FILL / WATER-SUPPLY CLUE
Samsung 4C / 4E washer code: the washer is not filling with water.
IMMEDIATE ACTION
Hot hose to hot, cold to cold, no kinks
Next stepValves fully open; unplug 1 minute
Still on: request service
THE SHORT ANSWER
On Samsung washers, 4C and 4E (also nF) mean the washer is not filling. Samsung’s checks: connect the hot hose to the hot inlet and the cold hose to the cold inlet with no kinks, keep both water valves fully open, insert the drain hose 6 to 8 inches into the drain pipe without kinks, and clean the supply filters. Unplug the washer or switch off its breaker for 1 minute, then try again. If the code stays, request service.

What 4C / 4E means
Samsung’s code list groups 4C, 1 4C, nF and 4E under “not filling.” It lists six steps and ends with service if the code persists. A related group, 4C2, 4E2, CE, 14C2 and nF1, is a different problem: Samsung says it means the cold supply water is extremely hot because the hoses are swapped, and needs no service.
How it appears: 4C or 4E on the display; some models show 1 4C or nF. Codes vary by model, so check your manual.
Check in this order
- Check the hose connections. Connect hot to hot and cold to cold. The hoses must not be bent or kinked. Samsung says not to use Flood Safe hoses.
- Keep the water valves fully open. Both valves must stay fully open during the cycle.
- Check the drain hose. Insert it 6 to 8 inches into the drain pipe, with no kinks.
- Reset the power. Unplug the washer or switch off its breaker for 1 minute, then restore power and try again.
- Clean the supply filters. Shut off the valves, disconnect the hoses, clean any debris out of the filters, then reconnect and open the valves fully.
If 4C / 4E comes back
Samsung says to request service if the code persists, through its Support Center. Tell them:
- The model number (where to find it).
- That the code is 4C, 4E or nF, and that both valves are fully open with the hoses connected hot to hot and cold to cold.
- That you cleaned the supply filters and did the 1-minute reset.
Not filling vs swapped hoses
| Codes | What Samsung says | Owner steps |
|---|---|---|
| 4C, 1 4C, nF, 4E | The washer is not filling | Hoses hot to hot and cold to cold with no kinks, valves fully open, drain hose 6 to 8 inches in, 1-minute power reset, clean the supply filters |
| 4C2, 4E2, CE, 14C2, nF1 | Cold supply water is extremely hot, so the hoses are swapped | Connect cold to the cold inlet and hot to the hot inlet, typically blue to blue and red to red; no service needed |
