Why is no water entering my Samsung washing machine?
When you start a wash cycle and your Samsung washing machine doesn't fill with water, it's frustrating. However, the issue is often straightforward to fix. Samsung machines are designed to be energy and water-efficient, and will typically display an error code like **4E, 4C, or E1** if there is a genuine problem with the water supply.Before calling a technician, follow this complete guide to diagnose and resolve the issue.

## 1. The Most Common Causes and Quick Fixes
### Check the Basics First
Start with the most obvious but easily overlooked steps.
- **Water Supply Valves** : Ensure both the hot and cold water faucets connected to the machine are fully open. Sometimes they are turned off during maintenance and forgotten.
- **Hose Kinks and Bends** : Pull the machine out gently and inspect the water inlet hoses at the back. A kinked, bent, or pinched hose will severely restrict or block water flow. If the hose is damaged, it will need to be replaced.
- **Connected Correctly** : Confirm the hot water hose is connected to the hot water valve on the machine and the cold to the cold valve. Swapped connections can cause errors (like nF1 or 4C2) and disrupt the automatic temperature control that uses a mix of both lines.
### Understand the "Weight Sensing" Feature
It's important to know that your machine uses a sensor to weigh the load before filling. When you start a cycle, the drum will rotate for **2-5 minutes** without water while it calculates the load weight. During this time, you might see "Weight Sensing" on the display or just rolling lines. This is normal—the water will only enter after this process is complete.

## 2. Step-by-Step Solutions to Restore Water Flow
### Clean the Inlet Mesh Filter
If the above checks don't resolve the issue, the culprit is likely a blocked mesh filter. These small screens are located at the water inlet on the back of the machine and are designed to catch rust, sediment, and debris from your plumbing. Over time, they can become completely clogged.
1. **Power Off and Unplug**: Switch off the machine and unplug it from the electrical outlet for safety.
2. **Turn Off Water**: Close the water supply valves completely.
3. **Access the Hoses**: Move the machine to access the back. Have a small container and a towel ready, as residual water will spill out.
4. **Remove the Hose**: Unscrew the water inlet hose from the back of the washing machine. You may also need to detach the L-shaped arm connecting it.
5. **Extract and Clean the Filter**: Using a pair of pliers, gently pull out the small mesh filter from the valve. Rinse it thoroughly under a strong stream of water until all debris is removed. Ensure you clean both the mesh and the threaded connector.
6. **Reassemble and Test**: Push the clean filter back into place. Reattach the L-shaped arm and the water hose securely, ensuring they are watertight. Turn the water valves back on. Plug the machine in and run a test cycle. **Samsung recommends cleaning these filters at least twice a year to prevent future problems**.
### Clean the Detergent Drawer
Occasionally, a blockage isn't in the hose but the detergent drawer. A build-up of detergent or fabric softener can obstruct the water flow path, causing a water supply error.
1. Pull out the detergent drawer completely.
2. Check for any obstructions, clumps of detergent, or residue.
3. Rinse the drawer under warm water and clean the compartment inside the machine.
4. Dry and reinsert the drawer, then test the cycle.

## 3. Advanced Checks and When to Call a Pro
### Cycle Power and Calibrate the Washer
After fixing any physical issues, it's a good idea to reset the machine's electronics. Unplug the washer or turn it off at the circuit breaker for **at least one minute** to fully reset the system.
Some models may also benefit from a recalibration. This tells the machine's sensors to correctly weigh the load.
- Ensure the drum is empty.
- On many models, you can enter Calibration Mode by pressing and holding **Temp.** and **Delay End** for 3 seconds until "Cb" appears. Then press **Start/Pause**. The drum will rotate for a few minutes and then turn off automatically. **Check your user manual for the exact button combination for your specific model**.
### Low Water Pressure and Environmental Factors
Your washing machine requires a water pressure between **0.5 bar and 8 bar** to function correctly. If the pressure from your mains supply is too low, the machine will not fill.
- **Seasonal Changes**: If your machine is installed with only a cold water line, it may stop working in winter when the water temperature drops below 60°F. The machine may still try to mix in hot water, so connecting a hot water line is recommended to prevent errors. Some models have a "Tap Cold" or "Coldest" setting that can bypass this.
- **Water Heater**: A water heater set too low (below 120°F) or simply empty of hot water after running multiple appliances can cause issues, especially during cycles that call for warm or hot water.
### When to Call Samsung Support
If you have tried all these steps and the machine still will not fill, the problem may be internal—such as a faulty water inlet valve or a problem with the main control board (PBA). **If you see a continuous error code like 4E or 4C after troubleshooting, or if the machine continuously fills without stopping, turn off the water valves and contact a Samsung Service Center for professional assistance**.
