Why the washing machine does not fill with water

The things are inside the washing machine, the powder is poured in, the program is selected, the button is started, but... silence. The water does not make noise, the drum is motionless. If your machine has a display, you may see an error code (H20, IE, 4E, E11, F02), quietly telling you about the problem - the machine does not fill with water.

What steps should be taken if the washing machine has stopped filling with water?

Conduct a visual inspection of the machine from all sides.

Check if there are any puddles on the floor under the device. Possible causes for their appearance:

If the pipe through which water enters the washing machine is deformed or burst, this leads to a leak. Visually inspect the pipe for cracks and bends.
The water supply hose supplies water to the washing machine. If the inlet hose is damaged or has become detached from the connection fitting, water will end up on the floor. Check the integrity of the hose and make sure it is connected correctly.
If the washing machine tank is damaged or has cracks, the leak will result.

In these cases, it is necessary to replace damaged parts to restore normal operation of the machine.

Check for water in the tap

Make sure that water can flow freely into the machine. Sometimes users forget to open the tap before starting the wash. Check the filters at the entrance to the washing machine. They can become clogged, which makes it difficult to feed.

Analyze the error that is displayed on the display.

Unusual symbols, numbers or messages flashing on the screen indicate a water intake error. Detailed information about the error code or message is available:

In the instructions for your device,
On the internet on forums of the SMA user community,
On the manufacturer's official website.

Restart the cycle

Rebooting is a short-term shutdown and subsequent switching on of the device. In some cases, technical failures may occur due to temporary software failures. This simple process, as first aid for updating the washing machine programmer, can return the equipment to stable operation.

If after all these steps the water still does not collect, make sure there are no other problems.

The main reasons why the washing machine does not fill with water

The shut-off valve is closed

Make sure the handle of the shut-off valve (in front of the machine) is in a position that allows water to flow freely. The handle is parallel to the pipe when the water is open and perpendicular to the pipe when it is closed.

The washing machine door is not closed

Make sure that the laundry in the drum does not interfere with the door closing. Place the laundry so that it does not extend beyond the drum and does not interfere with the door closing. Avoid overloading the drum.

The inlet hose is kinked

Check for kinks or twists in the water hose. Disconnect the hose from the back of the washing machine and the water faucet. If there are filters at the end of the water hose, check them for blockages. Straighten the water hose, remove any kinks or pinches so that water can flow freely under pressure.

Clogged inlet valve filter

The inlet valve is located at the rear of the washing machine at the point where the hose connects. There is a small filter at the entrance to the inlet valve, which can become clogged over time due to poor quality water from the tap. To clean the valve, unscrew the nut of the inlet hose, remove the filter with pliers and thoroughly clean it from accumulated dirt.

Incorrect drain connection

When connecting a washing machine on their own, many people prefer a simplified method, running the drain hose straight to the sewer coupling. It is important to note that the recommended drain point should be located at a level of 60-80 cm from the floor. A low position of the outlet or a long drain pipe complicates pumping out water, slowing down the pump and increasing the risk of breakage. Incorrect connection of the drain system disrupts the washing cycle, since the machine is unable to empty the used water in the tank for a new set. Drainage problems are accompanied by a humming motor, leaks, and an unpleasant odor around the drain pump.

Main faults that prevent the washing machine from filling with water

If, despite all the measures taken, the tank still does not fill, there may be malfunctions of certain components of the washing machine. For an accurate diagnosis, it is recommended to contact a professional from the service center.

Water supply valve

The accumulation of scale or foreign particles in the valve causes it to become clogged. As a result, the valve does not close or does not open completely, which prevents water from being drawn in normally. Long-term use and frequent washing cycles lead to wear of the sealing elements of the inlet valve. The causes of failure may also be as follows:

Electrical failures,
Increased pressure in the supply system,
Chemical deposits due to hard water or aggressive detergents.

Hatch locking device

Regular opening and closing of the washing machine door leads to wear of the mechanical parts of the UBL. If the door is not aligned properly, the hatch lock experiences excess pressure. The sealing rubbers that ensure the tightness of the device are subject to wear, fail and cause the door to jam or not fully lock.

Control module or programmer

Malfunctions in the washing machine's electrical system (voltage drops, broken wires, short circuits) affect the module's ability to send signals to control washing programs. Exposure to moisture and poor-quality powder causes corrosion on the control module or programmer boards. It is necessary to replace the control module or perform a firmware reflashing procedure.

Water level sensor (pressure switch)

The purpose of the pressure switch is to accurately record the amount of water that is collected in the machine's tank. You can use a multimeter to check the electrical resistance of the sensor, after disconnecting the washing machine from the power source and disconnecting the wires from the water level sensor. This element cannot be repaired, so it must be replaced with a new one.

Contacts and wiring in the UBL and filler valve circuit

During long-term operation and vibrations of the washing machine, the wires can wear out, and the contacts can oxidize in conditions of high humidity or burn out. Whatever the cause of the problem, it is impossible to fix it without special knowledge. The technician checks the inlet valve circuit, identifies the place where the signal is broken. Then he performs repairs by twisting the damaged wires. In case of damage to the contacts, the specialist solders or replaces the contact group as a whole.

New automatic machine does not fill the drum with water

When the washing machine does not fill during its first use, it is important to remain calm and carry out several checks in sequence. Make sure that there is water in the water supply and the inlet valve is not closed. Check that the hatch door is locked, otherwise the machine will not recognize the signal that it is ready to start the program. Correct installation of the washing machine is the key to its smooth operation. If this important step is violated, the device cannot fill with water. The cause of the problem is primarily incorrectly connected water hoses - they create a barrier to the normal flow.

The washing machine is humming but no water is coming into the drum

An unusual noise indicates that the inlet hose is clogged or pinched. The filter mesh in the inlet valve may be clogged, which causes noise when filling with water due to the reduced flow area. Pay attention to the electromagnetic valve. This key component controls the water supply to the machine, and its malfunction may be the cause of the problem. Try draining the water from the hose and directing air through it using a vacuum cleaner. If the valve is working properly, you can hear a characteristic click.

Error codes on the display

When a combination of different numbers and letters appears on the washing machine display, this is a key signal about possible problems that require a quick solution. The machine tells you about a malfunction (each manufacturer uses its own error coding system):

Pressure switch – F04, F10, F29, E7, E33, PE, IC;
Door locking devices – E42, E16, Ed, dE, ddC, F06, F16.

Conclusion

Washing machines are complex electromechanical systems, and intervention without the necessary knowledge affects the correct operation of the device. Purchasing unsuitable spare parts or installing them incorrectly causes additional costs and repeated problems. Accurate diagnostics and professional repair ensure reliability and extend the service life of the washing machine. If the problems are related to electronic components (control boards or sensors), it is recommended to contact a service center for professional diagnostics and qualified assistance. Specialists have experience, the necessary equipment and guarantee the operability of your household appliances for many years.
