Why Won't My Samsung Washing Machine Fill With Water?

Medium fix Updated 28 March 2026
Quick Fix

Check that both the hot and cold water tap(s) behind the machine are fully open, then restart the cycle — this resolves the fault in the majority of cases (takes about 5 minutes).

Fault description

When a Samsung washing machine won't fill, the drum stays dry or nearly dry after the cycle begins. You may hear the machine humming as it tries to draw water, or the cycle may pause and display an error code such as 4E, E1, or 4C on the control panel. These codes all point to the same underlying problem: the machine is not detecting enough water entering the drum within the expected time.

The water-fill system involves the inlet hoses, the inlet valve, the water pressure sensor (also called the pressure switch), and the control board. A fault anywhere along this chain can stop water from entering. The good news is that the most common causes are simple and require no special tools to fix. Working through the checks below in order will resolve the problem for most households.

Causes

  • Water supply tap turned off or partially closed — The tap(s) feeding the machine must be fully open. Even a tap that is three-quarters open can restrict flow enough to trigger a 4E or 4C error.
  • Kinked or blocked inlet hose — The fill hose can become kinked if the machine has been pushed back against the wall. Sediment or a mesh filter blocked with debris inside the hose connection can also reduce flow to a trickle.
  • Clogged inlet valve mesh filter — Samsung inlet hoses connect to the machine via a valve that has a small mesh filter screen. This screen traps grit and limescale over time and can block completely, preventing water from entering.
  • Faulty water inlet valve — The solenoid-operated inlet valve opens when the control board sends a signal. If the solenoid coil burns out or the valve body cracks, it will not open and no water will enter, even with full mains pressure available.
  • Faulty water pressure sensor (pressure switch) — The pressure sensor tells the control board how much water is in the drum. If it fails or its connecting hose becomes blocked, the board may incorrectly believe the drum is already full and stop filling.
  • Control board fault — In a small number of cases the main PCB fails to send the correct signal to open the inlet valve. This is usually only suspected after all other components have been checked and ruled out.

Step-by-Step Fix

  1. 1

    Check the water supply taps

    Locate the hot and cold taps on the wall behind the machine and make sure both are turned fully anti-clockwise (open). It is surprisingly common for a tap to be accidentally knocked partially closed during cleaning or a house move. Turn the tap fully open, restart the cycle, and watch whether water begins to enter.

  2. 2

    Inspect the inlet hoses for kinks

    Pull the machine gently away from the wall and run your hand along both inlet hoses. Straighten any kinks you find. Also check that the hoses are not being pinched by the machine's feet or the wall. Once straightened, push the machine back carefully so the hoses are not compressed.

  3. 3

    Clean the inlet hose mesh filters

    Turn off the water supply taps, then unscrew the inlet hoses from the back of the machine — have a towel ready as residual water will spill. At the end of each hose connection you will see a small plastic mesh filter. Remove it with needle-nose pliers, rinse it under the tap, and use an old toothbrush to clear any limescale or grit. Refit the filters, reconnect the hoses, and turn the taps back on.

  4. 4

    Check household water pressure

    Samsung machines require a minimum dynamic water pressure of around 0.5 bar to fill correctly. If other taps in your home also have low pressure, contact your water supplier. If pressure is only low at the washing machine connection, check for a partially closed isolator valve on the supply pipe.

  5. 5

    Test the water inlet valve

    With the machine unplugged, remove the top or rear panel (depending on your model) to access the inlet valve. Disconnect the electrical connectors and use a multimeter set to resistance (Ω) to test each solenoid coil — a healthy coil typically reads between 200 Ω and 500 Ω. A reading of zero or infinity indicates a failed coil and the valve should be replaced.

  6. 6

    Inspect the pressure sensor and its hose

    The pressure sensor is a small round component, usually mounted on the side of the cabinet, connected to the drum by a thin rubber or plastic hose. Disconnect the hose and blow gently through it to check it is clear. If the hose is blocked or cracked, replace it. If the hose is clear but the fault persists, the sensor itself may need replacing.

  7. 7

    Reset the machine

    After completing any repair, perform a factory reset by turning the programme dial to the off position, then holding the Start/Pause button for five seconds. This clears stored error codes including 4E, E1, and 4C. Run a short rinse cycle to confirm the machine fills correctly before running a full wash.

When to call a service technician

If you have worked through all the steps above and the machine still will not fill, the fault is likely inside the machine's electronics or the inlet valve wiring loom — areas that require safe handling of mains-voltage components. A service technician has the diagnostic tools to test the control board and valve circuits accurately without risk of electric shock or further damage to the appliance.

You should also call a service technician if you notice water leaking from the inlet valve body, if the hose connections are corroded and cannot be safely removed, or if the machine is still under Samsung's manufacturer warranty, as DIY repairs may affect your cover.

Prevention

The parts most commonly replaced when a Samsung washing machine won't fill are the water inlet valve (the single most frequent replacement), the inlet hose mesh filter screens, and the water pressure sensor. Keeping the mesh filters clean every six to twelve months is the most effective way to prevent a recurrence, particularly in hard-water areas where limescale builds up quickly. Using a descaling tablet in a maintenance wash every three months also helps protect the inlet valve seat from scale deposits.

Frequently Asked Questions

What does the 4E error code mean on a Samsung washing machine?

The 4E code (also shown as E1 on older models and 4C on some ranges) means the machine did not detect enough water entering the drum within the allowed time. It is a water supply error, not a mechanical breakdown. Start by checking that the water taps are fully open and the inlet hose filters are clean.

Can I use my Samsung washing machine if it shows a 4C error?

No — when a 4C or 4E error is active the machine will pause or cancel the cycle to prevent the motor and heating element from running dry. You need to resolve the water supply fault before the machine will complete a wash. Once fixed, clear the error with a reset as described in Step 7 above.

How do I know if my inlet valve needs replacing rather than just cleaning?

If cleaning the mesh filters and confirming full water pressure does not restore filling, test the valve's solenoid coils with a multimeter. A coil reading outside the 200–500 Ω range, or a valve that leaks water when the machine is off, indicates the valve needs replacing rather than cleaning.

My Samsung machine fills very slowly but does not show an error — is this the same fault?

Slow filling is usually caused by a partially blocked mesh filter or a tap that is not fully open, rather than a complete valve failure. Work through Steps 1 to 3 first. If flow is still slow after cleaning the filters, low household water pressure or a partially seized inlet valve is the likely cause.

Is a Samsung washing machine that won't fill covered under warranty?

Samsung's standard manufacturer warranty covers component failures but not faults caused by external factors such as low water pressure or blocked supply pipes. If your machine is within the warranty period, contact Samsung support before attempting any internal repairs, as opening the machine yourself may void the warranty.
