Fault code guide

Samsung washing machine error codes

Samsung calls these “information codes”. Many point to something you can sort out in a few minutes, such as a closed tap or a blocked filter. Others mean a part needs testing, and this page tells you which is which.

Checked against Samsung’s own guidance, October 2026

Before you check anything: switch the appliance off at the wall first. Never remove covers or panels from a machine that’s plugged in. If you smell burning, see scorching or the appliance trips your electrics, leave it switched off and get it looked at.

Samsung washing machines and washer dryers

What each code means

Newer Samsung machines show codes ending in C (such as 4C); older ones often show the same fault ending in E (4E). They mean the same thing.

How to clean a washing machine pump filter
  1. 4C4EE1 Water isn’t coming into the machine, or not quickly enough.

    Try this first
    • Check both water taps behind the machine are fully open.
    • Make sure the inlet hose isn’t kinked, squashed or frozen.
    • Turn off the tap, unscrew the hose from the machine and rinse the small mesh filter inside the connection.

    If the taps are on and water is reaching the hose but the machine still won’t fill, the inlet valve or water level sensor needs testing.

  2. 4C24E2 The incoming water is too hot.

    Try this first
    • Check the fill hose is connected to the cold supply, not the hot tap.

    If it’s definitely on the cold supply, the temperature sensing needs checking.

  3. 5C5E The machine can’t drain the water.

    Try this first
    • Switch off at the wall and clean the debris filter behind the small hatch at the bottom front. Have towels and a shallow tray ready.
    • Check the drain hose isn’t kinked, blocked or frozen, and that it runs cleanly to the waste pipe.
    • If the kitchen sink drains slowly too, the blockage may be in the shared waste pipe.

    If the filter and hose are clear and the code returns, the drain pump has usually failed.

  4. dCdE The door isn’t closed properly.

    Try this first
    • Open the door and close it again firmly.
    • Check no clothing is caught in the door seal.

    If the door is shut and the code stays, the door lock or catch is likely at fault.

  5. dC1dE1 The main door lock isn’t working correctly.

    Engineer if it returns
    • Switch off, wait a minute and restart the cycle.

    If it comes back, the door lock needs replacing. It’s a common, reasonably priced repair.

  6. ddCDDC The Add Door was opened without pausing the cycle first.

    Not a fault
    • Close the Add Door, then press Start/Pause to carry on.

    No repair is needed unless the code appears with the Add Door closed.

  7. UEUb The load is unbalanced, so the machine won’t spin at full speed.

    Try this first
    • Spread the laundry out evenly in the drum.
    • Avoid washing a single heavy item, such as a bath mat or duvet, on its own.
    • Check the machine stands level and doesn’t rock.

    If small, even loads still trigger it, the suspension or motor speed sensing needs checking.

  8. Ur The machine has detected imbalance and added extra rinsing.

    Not a fault
    • Press any button to clear the message.

    This is information rather than a fault.

  9. LCLELC1LE1 A problem with the drain hose.

    Try this first
    • Check the end of the drain hose is raised to the right height and not lying on the floor.
    • Make sure the hose isn’t blocked.

    If the hose is correctly fitted and clear, the cause needs tracing on site.

  10. OCOEOF Too much water has entered the machine.

    Engineer if it returns
    • Let the machine drain, then restart the programme.

    If it happens again, the water level sensor or inlet valve is usually at fault.

  11. 1C1E The water level sensor isn’t working correctly.

    Engineer if it returns
    • Switch off at the wall for a minute, then restart.

    If it returns, the level sensor or its tube needs checking.

  12. 3C3E The motor isn’t running as it should.

    Engineer if it returns
    • Check the drum isn’t overloaded, then restart the cycle.

    If it comes back, the motor, its wiring or the control board needs testing.

  13. HCHE A heating problem: the water is getting too hot or not heating properly.

    Engineer if it returns
    • Switch off, wait a minute and restart.

    If it comes back, the heater, temperature sensor or wiring needs testing. Leave it off if it also trips your electrics.

  14. ACAE The machine’s circuit boards aren’t communicating.

    Engineer if it returns
    • Switch off at the wall for a minute, then restart.

    If you see it again, the wiring between the boards or a board itself needs checking.

  15. 8C8E The vibration sensor isn’t working correctly.

    Engineer if it returns
    • Restart the cycle.

    If it keeps appearing, the sensor or its connection needs checking.

  16. UC9C19E19C29E2 The power supply voltage is too low or unstable.

    Try this first
    • Plug the machine directly into a wall socket rather than an extension lead.
    • Check the plug is pushed fully in.

    If it keeps happening on a direct socket, the power board or your supply needs checking.
