Is your Samsung washing machine showing a 4C, 4E, or NF error code? Don’t panic — these codes all point to the same problem: your machine is not getting enough water (or no water at all). Here’s everything you need to know to fix it fast.

 What Do 4C, 4E, and NF Mean?

All three codes mean the same thing: your Samsung washer started a cycle but did not detect enough water entering the drum within the expected time.

✅ Quick Fixes to Try First (Before Calling a Technician)

Try these steps in order before anything else:

1. Check that the water tap is fully open — the inlet tap behind the machine must be turned all the way on.
2. Check your home water supply — confirm water is flowing from other taps in the house.
3. Straighten the inlet hose — a kinked or bent hose will block water flow.
4. Clean the inlet hose mesh filter — a clogged filter is the #1 cause of this error.
5. Restart the machine — turn it off, unplug for 1 minute, then restart the cycle.

If none of the above works, read the detailed steps below or call 0704843613 for professional help.

🔍 What Causes the 4C / 4E / NF Error on a Samsung Washer?

The Samsung washing machine monitors how long it takes for water to reach the required level. If the drum doesn’t fill within a set time, it throws the 4C, 4E, or NF error and stops the cycle to protect the machine.

Common causes include:

• Closed or partially open water supply tap
• Low water pressure from the mains supply
• Kinked, twisted, or crushed inlet hose
• Blocked mesh filter inside the inlet hose connector
• Faulty water inlet valve (solenoid valve)
• Damaged or broken water level pressure sensor
• Wiring or control board fault (rare)

🛠️ Detailed Step-by-Step Fix Guide

Step 1: Check the Water Supply Tap

The water inlet tap is usually located on the wall directly behind your washing machine.

• Make sure it is turned fully counterclockwise (fully open).
• If the tap has not been used in a long time, it may be stiff or partially seized — try opening it further.
• Also check that water is running normally in your kitchen or bathroom to rule out a supply outage.

Step 2: Inspect and Straighten the Inlet Hose

• Pull the machine slightly away from the wall.
• Visually inspect the blue or grey inlet hose running from the tap to the back of the machine.
• Look for any kinks, bends, or crushing — even a slight kink can restrict water flow enough to trigger the error.
• Straighten the hose and ensure it is not trapped under the machine or bent sharply around a corner.

Step 3: Clean the Inlet Hose Mesh Filter (Most Common Fix)

This is the number one cause of 4C/4E/NF errors and is very easy to fix yourself.

What you need: A pair of pliers, a small bowl, and a toothbrush.

Steps:

1. Turn off the water supply tap.
2. Place a towel or small bowl under the hose connection at the back of the machine.
3. Unscrew the inlet hose from the back of the washing machine by turning it counterclockwise. Some water will spill — this is normal.
4. Look into the hose fitting on the machine — you will see a small mesh screen (filter).
5. Carefully pull out the filter using pliers or your fingers.
6. Rinse it under running water and use a toothbrush to remove any sediment, rust, or debris.
7. Reinsert the filter, reattach the hose securely, and turn the water back on.
8. Run a test cycle to see if the error clears.

⚠️ Also check the filter at the tap end of the hose — there is often a second filter where the hose connects to the tap.

Step 4: Check Your Water Pressure

Samsung washing machines require a minimum water pressure of 0.5 bar to function correctly.

• If you live in an apartment building or area with known low water pressure, this may be the issue.
• You can test pressure by holding a bucket under your tap for 6 seconds — it should fill at least 6 litres.
• If pressure is too low, contact your water utility provider or consider installing a booster pump.

Step 5: Check the Water Inlet Valve

The water inlet valve (also called the solenoid valve) is an electrically controlled valve inside the machine that opens to let water in when a cycle starts.

Signs it has failed:

• You can hear the machine trying to fill but no water enters.
• The hose, filter, and tap are all fine, but the error persists.

What to do:

• This repair requires accessing the back or top panel of the machine.
• The valve can be tested with a multimeter for continuity.
• A failed inlet valve must be replaced.

🔧 This is best handled by a qualified technician. Call 0704843613 to book a repair.

Step 6: Check the Pressure Sensor (Water Level Sensor)

The pressure sensor tells the machine how much water is in the drum. If it is faulty, the machine may think it is not filling even when water is entering normally.

Symptoms:

• Water appears to be entering the machine, but the error still appears.
• Machine fills then immediately stops and throws the error.

What to do:

• The pressure sensor is connected to a small rubber hose inside the machine.
• Check that the rubber hose is not cracked, blocked, or disconnected.
• A faulty sensor must be tested and replaced by a technician.

Step 7: Reset the Machine

After completing any of the above fixes, always reset the machine before running a new cycle:

1. Press and hold the Power button to turn the machine off.
2. Unplug the machine from the wall socket.
3. Wait 1–2 minutes.
4. Plug back in and power on.
5. Select a wash cycle and start — the error should be gone.

❓ Frequently Asked Questions

Q: Can I still use my washing machine with a 4C error? No. The machine will not run a cycle until the error is resolved. Attempting to bypass it can damage the pump and drum bearings from running dry.

Q: Is the 4C error covered under Samsung warranty? If your machine is within the warranty period and the fault is with the inlet valve or pressure sensor (not user error like a closed tap), it may be covered. Contact Samsung Kenya or your local service agent.

Q: How much does it cost to fix a 4C error in Kenya? Cleaning a blocked filter is free and DIY. Replacing an inlet valve or pressure sensor typically costs KSh 1,500 – KSh 4,500 depending on the part and model. Call 0704843613 for a quote.

Q: My Samsung washer shows 4C2 — what does that mean? The 4C2 error specifically indicates a problem with the hot water supply on machines that have both hot and cold water inlets. Check the hot water inlet hose and filter separately.
