What error 4C means
Error 4C (also shown as 4E on some front-loaders) indicates the machine is not receiving enough water within the expected time during a cycle. The root cause is almost always a water-supply or inlet-hose issue — rarely an internal fault.
Safety first
Step-by-step fix
- 1
Step 1
Check the water taps
Make sure both water taps (hot and cold, if applicable) connected to the machine are turned fully ON. Test the flow by disconnecting the hose and running water into a bucket for 10 seconds.

Step 2
Inspect the inlet hose
Look for kinks, twists, or blockages along the length of the hose. Straighten any bends. Check the filter mesh inside the hose end connected to the machine.
Pro tip: If you see a white crusty build-up inside the mesh filter, that's calcium from hard water. Clean it with vinegar.

Step 3
Clean the inlet filter
Use pliers to gently unscrew the inlet hose from the back of the machine. Using tweezers, pull out the tiny mesh filter that sits just inside the inlet valve. Rinse under running tap water until clear, then reinsert.
Caution: Hold the filter gently — the mesh can deform if pinched too hard.

Step 4
Check water pressure
Samsung front-loaders require a minimum water pressure of 0.5 bar (roughly 5 metres of head). If your building supply is low during peak hours, you'll see this code repeatedly. A booster pump resolves this permanently.

Step 5
Reset and test
Reconnect everything, plug the machine back in, and run a short rinse-only cycle with no clothes. If 4C returns, move to the 'When to call a technician' section below.
When to call a technician
- • 4C returns immediately after every cycle, even with new hose and cleaned filter
- • You hear a clicking sound from the back of the machine when it tries to fill (faulty inlet valve)
- • Machine is under Samsung warranty — attempting a self-repair may void it
Frequently asked questions
What does 4C mean on a Samsung washing machine?
4C indicates the machine isn't receiving enough water during the fill cycle. Almost always caused by a closed tap, kinked hose, or clogged inlet filter — not an internal fault.
How do I reset my Samsung washing machine after fixing 4C?
Unplug the machine for 60 seconds, plug back in, and run a short rinse-only cycle to confirm the fix. No button combination is needed for a 4C reset.
Can I fix error 4C myself?
Yes — roughly 90% of 4C cases are taps, hoses, or filters. All fixable at home in under 15 minutes with a pair of pliers. Only call a technician if the valve itself is faulty (repeated 4C after every fix).
How much does a Samsung technician charge for 4C in India?
A home-visit diagnostic charge is typically ₹400–700 in metro cities. If the inlet valve needs replacement, total cost runs ₹1,500–2,500 including parts and labour.
