Samsung Washer Not Filling or Keeps Filling (How To Fix)

A Samsung washer that is not filling or keeps filling can be a headache, especially when you have loads of laundry. It will not only cause pilling up of dirty laundry but also cause flooding in your laundry area.

If your Samsung washer is not filling or keeps filling, it could be due to a crooked water supply hose, low water pressure, faulty water level switch, malfunctioning water inlet valve, or faulty main control board. Get a service member to inspect these parts for any faults and replace them if damaged.

The water inlet valve regulates the amount of water entering your washer. It connects the two hoses to the washer and controls the flow of hot and cold water. Therefore, if it is damaged, it can cause water not to fill. Test to determine if the valve has failed and replace it.

Check if the water supply hoses are crooked or blocked and replace them. Ensure that the water supply valves are open and ensure you are not using the flood-safe hose. Additionally, ensure that the hot and cold water hoses are correctly connected.

Check the pressure in the water inlet valve to ensure it reads at least 20psi. If the pressure is lower, check whether there are open faucets or shower heads around the house and shut them.

Try running a spin cycle after this and check if the water will fill. Similarly, the washer will continue filling if the water pressure is too high. The water pressure issue does not necessarily indicate a problem with the washer. Get a plumber to check the water pressure and resolve the issue.

If your washer was installed in summer with only a cold water line, it might display an error code and not fill in winter. In this case, connect a hot water line to clear this error.

If your washer keeps filling, it could be due to a faulty pressure switch. The pressure switch shuts off power when the washer has reached a proper water level. Therefore, if it’s defective, water will continue filling and cause an overflow.

Before replacing the pressure switch, check the air tube connecting to it to ensure it’s not blocked or leaking. If it’s all clear, you must replace the pressure switch.

Top Reasons Samsung Washers Not Filling or Keeps Filling

Samsung washers are some of the most energy-efficient washing machines on the market. They utilize various technologies to minimize water wastage and maximize their effectiveness. Sometimes these technologies fail, making them not fill or not stop filling.

Samsung washers are not filling or keep filling due to a faulty water inlet valve, malfunctioning water level switch, clogged water level switch pressure hose, incorrect water pressure, a defective lid switch, or a faulty main control board. Check these parts and replace them if damaged.

Faulty Water Inlet Valve

A Samsung washer will keep filling or not filling if the water inlet valve is malfunctioning. The water inlet valve controls the water getting into the washer. It has two woven ports that connect to the hot and cold water hoses at the back of the washer.

Each port has a solenoid valve that transmits electric power to open and close the valve. Similarly, it has a filter screen that traps debris to prevent damaging the washer. Continuous accumulation of debris can clog the filter, allowing insufficient water to pass through it.

If the solenoid valves are broken, the valve will malfunction, causing the machine to overfill or not fill. Check if the screen is clogged and clean it. Similarly, check if the valve is functioning correctly and replace it if damaged.

Malfunctioning Water Level Switch

The water level switch signals the water inlet valve to supply water into the tub and stop when it’s full. It has two contact points, where one connects to the motor. The switch signals the motor to start the spinning cycle when water fills the tub.

When the water level switch is faulty, it won’t signal the water inlet valve to stop filling. Similarly, it may signal the valve to stop immaturely when the tub isn’t full. Check if the switch is faulty and replace it.

Clogged Water Level Switch Pressure Hose

The water level switch has a power hose that connects it to the outer tub’s air dome. When the tub fills with water, it creates pressure to power the inlet valve and shut it. If the valve is clogged or leaking, it can reduce the pressure and cause the valve to continue filling the washer. In this case, replace the clogged hose.

Incorrect Water Pressure

Low water pressure can make a Samsung washer not fill. It can result from open indoor and outdoor faucets or shower heads. Similarly, a clogged inlet valve filter or hose can reduce water pressure, causing the washer not to fill.

Close all other faucets and shower heads and attempt to run a washing cycle to see if the washer fills. Check the inlet valve filter for any kink, clean it, and return it. Call a plumber to check and resolve the issue if the water pressure is still low.

Damage To The Main Control Board

Check the main control board when you have confirmed that all the above parts are functioning correctly, but your washer won’t stop acting up. The main control board regulates all the functions of the washer. If it’s faulty, the water inlet valve and water level switch malfunction and cause the washer to overfill or not fill.

Check the main control board for loose wiring or signs of burns. If you notice any damage, contact a trained professional to check and replace the main control board if necessary.

How To Fix A Samsung Washer Not Filling Or Keeps Filling

A Samsung washer that will not fill means that you won’t do your laundry. Likewise, if the washer won’t stop filling, you may have to mop the entire laundry room floor. Luckily, it’s easy to diagnose and fix the problem by following the steps below.

To fix a Samsung washer that will not fill or keeps filling, check the water inlet valve, water level switch, water level switch pressure hose, and the main control board. Replace any of the damaged parts. Contact a plumber to check the water pressure.

Unplug the washer and turn off the water supply. Turn off the cold and hot water supply hoses and set a bucket to collect any water running from them. Use a flashlight to check the filters for any debris or clogging, and clean it if you find any gunk.

Remember that a clogged water filter can reduce water pressure and cause the machine not to fill. Check all the water outlets in your home to ensure they are not running. Try running a washing cycle and see if the tub will fill.

If the washer does not fill when no other water outlet is running, it could indicate a problem with water pressure. Call a plumber to check it out and fix it.

Test the valve for failure if the water filter screens are not blocked. Use a multimeter to test the solenoids for continuity; if it doesn’t register any resistance, it indicates they are faulty. Replace the entire water inlet valve if the solenoids are damaged.

To determine if the water level switch is faulty, use the manufacturer’s manual to determine its location, depending on your model. Disconnect the hose from the switch and check for any gunk or debris. Check the hose for any leaks, clean it, and reconnect it. If the hose is leaking, replace it.

Test the water level switch for electrical failure using a multimeter. Test the three terminals for continuity and if the multimeter does not record any resistance, replace the entire water level switch.

When you have replaced the faulty water level switch, water inlet valve, and any clogged pipes and filters, try running the machine to see if it functions properly. Check the main control board if the washer won’t fill or keeps filling.

Remove the screws securing the rear panel and raise it. Pull it upwards from the bottom and remove it. Unscrew the main control board housing and move it towards the left to detach it. Remove the top cover and check the components for burn marks or loose wiring.

If you notice any faults, consider replacing the main control board. But if you don’t see any physical signs that the main control board is faulty, contact a professional serviceman to check and replace it.

If your Samsung washer won’t fill or keeps filling, it may be because of a bent water supply line, low water pressure, a broken water level switch, a broken water inlet valve, or a broken main control board. Contact an expert to check these components for any issues and replace them if necessary.
