Causes Of 4c Error
The Samsung Washer 4C error code signals a water supply problem. This error stops the washer from filling with water. Several issues can trigger this error. Understanding these causes helps fix the problem quickly. Here are the common reasons behind the 4C error code.
Water Supply Issues
The most frequent cause is a problem with water supply. The water taps connected to the washer might be closed. Sometimes, the water supply is cut off due to maintenance or pipe damage. Without water, the washer cannot fill and shows the 4C error.
Clogged Inlet Filters
The washer has small mesh filters inside the water inlet ports. Dirt and debris can block these filters over time. When clogged, water flow reduces or stops. Cleaning these inlet filters often solves the 4C error.
Kinked Or Blocked Hoses
Water hoses carry water to the washer. If the hoses are bent, twisted, or blocked, water cannot reach the machine. This restriction triggers the 4C error. Check hoses carefully for kinks or obstructions and straighten or clear them.
Low Water Pressure
Low water pressure in the home affects the washer’s water intake. The washer needs enough pressure to fill properly. If pressure is too low, the 4C error appears. Testing and improving water pressure can fix this issue.
Checking Water Connections
Checking water connections is a key step when your Samsung washer shows the 4C error code. This code signals a water supply issue that stops the washer from filling properly. Simple problems like closed taps, bent hoses, or clogged filters often cause this error. Careful inspection of these parts can restore water flow and fix the error quickly.
Inspecting Water Taps
Start by making sure the water taps are fully open. Both hot and cold water taps must allow water to flow freely. Sometimes taps are partially closed or stuck, blocking water supply. Turn each tap clockwise and counterclockwise to check if they move smoothly. Replace any broken or leaking taps to avoid further issues.
Examining Hoses For Kinks
Next, check the hoses connecting your washer to the water taps. Hoses can bend or kink, which blocks water flow. Look closely along the entire length of each hose. Straighten any bends or kinks you find. Replace hoses that have cracks, leaks, or are very old. Secure hoses properly so they do not bend or twist during use.
Cleaning Inlet Filters
Inlet filters can collect dirt and debris over time. This buildup reduces water flow and triggers the 4C code. Turn off the washer and unplug it before cleaning. Unscrew the hoses from the back of the washer carefully. Look inside the hose ends or washer inlet ports for small mesh filters. Remove these filters and rinse them under running water. Use a soft brush if needed to clear stubborn debris. Reinstall the filters and hoses securely before testing the washer.
Testing Water Valve Components
Testing the water valve components is key to resolving the Samsung Washer 4C code. This code signals a water supply issue, often linked to the water valves. Checking these parts ensures the washer fills properly and avoids error codes. The process involves inspecting wires, measuring resistance, and testing voltage. Each step helps identify faulty components that block water flow.
Inspecting Valve Wire Harness
Start by examining the wire harness connected to the water valve. Look for loose connections, frayed wires, or corrosion. Damaged wires can stop electrical signals from reaching the valve. Make sure the harness fits securely on the valve terminals. Replace or repair any visible damage to restore proper function.
Using A Multimeter For Resistance
Set a multimeter to the ohms setting to measure resistance. Disconnect the wire harness from the valve. Touch the meter probes to the valve terminals. A normal valve usually shows resistance between 500 and 1500 ohms. A reading of zero or infinite resistance means the valve coil is broken or shorted. Replace the valve if the resistance is outside the normal range.
Performing Live Voltage Tests
Test the valve with the washer powered on to check voltage. Use caution to avoid electric shock. Set the multimeter to measure AC voltage. Place the probes on the wire harness terminals while the washer calls for water. The meter should show voltage when the valve is activated. No voltage means a wiring or control board issue. Confirm wiring integrity and control signals before replacing the valve.

Fixing Common Problems
Fixing common problems related to the Samsung Washer 4C code often resolves issues with water supply. This error code usually signals a problem with water flow into the washer. Addressing simple causes can restore your washer’s performance quickly. Here are some practical steps to fix the 4C code effectively.
Clearing Clogs In Filters And Valves
Clogs in the inlet filters or valves block water from entering the washer. Turn off the water supply and unplug the washer first. Remove the water inlet hoses from the back of the machine. Check the small mesh filters inside the hose or washer inlet. Clean any dirt or debris gently with a soft brush. After cleaning, reattach the hoses securely. This step often fixes water flow problems causing the 4C error.
Straightening Or Replacing Hoses
Kinks or bends in the water hoses reduce water pressure. Inspect the hoses behind the washer for any sharp bends or twists. Straighten any kinks to allow smooth water flow. If hoses show cracks or damage, replace them with new ones. Using flexible, kink-resistant hoses can prevent future issues. Proper hose condition helps maintain steady water supply and prevents error codes.
Adjusting Water Pressure
Low water pressure can trigger the 4C error code. Check the water taps connected to the washer and ensure they are fully open. If pressure remains low, test other water outlets in your home. Consider contacting your water supplier if low pressure is widespread. Some washers have a pressure switch that may need inspection. Adjusting or repairing this switch can improve water intake and fix the error.
Resetting The Washer
Resetting your Samsung washer is a key step when the 4C error code appears. This code signals a water supply issue. Resetting can clear minor errors and restore normal function. Follow simple steps to reset the washer safely and effectively.
Power Cycling Steps
Start by turning off your Samsung washer. Unplug it from the power outlet. Wait for about one minute to let the system reset fully. Plug the washer back in and turn it on. This power cycle can clear temporary faults and reset the control board.
Running A Test Cycle
After power cycling, run a test cycle without clothes. Choose a quick or rinse cycle for this test. Watch the washer to see if water fills correctly. The test cycle helps confirm if the reset solved the 4C code issue. If the error returns, further inspection may be needed.

When To Call A Technician
Knowing when to call a technician for your Samsung washer’s 4C error code can save time and prevent damage. Some problems need expert attention to fix safely and correctly. Recognizing the right moments for professional help is key to keeping your washer in good shape.
Signs Of Electrical Issues
Unusual sparks or burning smells indicate electrical trouble. The washer may not start or stop suddenly without reason. Flickering lights on the control panel also signal problems. These signs show that the washer’s electrical parts may be failing. Avoid using the washer until a technician checks it.
Persistent Error Codes
The 4C code may appear repeatedly even after basic fixes. Resetting the washer does not clear the error. Water supply and hose checks do not solve the issue. This persistence means the problem runs deeper than a simple clog or kink. A professional can diagnose and repair complex faults.
Professional Service Options
Authorized Samsung service centers offer expert repairs and genuine parts. Certified technicians have training specific to Samsung washers. They use specialized tools to identify hidden faults. Scheduling a service visit ensures the washer receives proper care. Some repairs may also be covered under warranty.
