Samsung Washing Machine 4E error code

The washer can't fill with water fast enough, so it stops and flags a water-supply problem. The inlet valves, supply hoses, water taps, or inlet filters are the usual culprits.

Also shown as: 4C, 4C1, NF, nF, 1 4C

Quick answer: Samsung washing machine error code 4E: water not filling — check tap, hoses, and inlet filter. The most common cause is water tap(s) closed or only partially open. Try this first — open the water taps fully. If that does not clear it, check the supply hoses for kinks.

What causes the 4E error?

  • Water tap(s) closed or only partially open
  • Kinked, bent, or blocked water supply hose
  • Clogged mesh filter at the water inlet
  • Low mains water pressure (should be 0.5–8 bar)
  • Hot and cold hoses swapped or incorrect drain hose placement
  • Blocked detergent dispenser drawer

How to fix Samsung 4E — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Open the water taps fully
    Confirm both the hot and cold water valves feeding the washer are turned fully open and left open while it runs. On some models a cycle using hot water will error even on Cold-labeled cycles if the hot line is shut.
  2. Check the supply hoses for kinks
    Power the washer off first. Move it away from the wall and inspect both inlet hoses for kinks, bends, or damage. Straighten any kinks and make sure the hot hose connects to the hot inlet and cold to cold.
  3. Power cycle the washer
    Unplug the washer or flip its circuit breaker for about 1 minute, then restore power and start a test cycle. Note the control buttons stay disabled for about 3 minutes after the code appears.
    Safety warning: Always unplug before touching hoses or filters.
  4. Clean the inlet mesh filters
    Turn off the water supply, disconnect the hoses from the back of the washer, and gently pull the small mesh screens from the inlet valves with pliers. Rinse them under running water, push them back in, reconnect the hoses tightly, and turn the water back on. Do this at least twice a year.
    Safety warning: Keep the water supply off while hoses are disconnected to avoid spills.
  5. Clean the detergent dispenser drawer
    Pull the drawer out, clear any caked detergent or obstructions, wash it out, and slide it back in. A blockage here can occasionally trigger the code.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • Code returns after all the basic checks and a power cycle
  • Water is leaking from supply hoses or inlet connections
  • Suspected failed water-inlet valve, wiring fault, or control-board issue — these need panel access
  • Burning smell, sparks, or any sign of electrical damage

Frequently asked questions

Can I just unplug it and the 4E will go away?

A power cycle clears temporary glitches, but if a tap is shut, a hose is kinked, or a filter is clogged, the code will come right back until you fix the cause.

What's the difference between 4E, 4C, and NF?

They mean the same thing — the washer isn't filling. Different regions and model generations just display different variants of the water-supply code.

Why do the buttons stop working when 4E appears?

Samsung disables the control panel for about 3 minutes after the code shows. Wait it out, then restart the cycle.
