Your Samsung washer might, from time to time, show the error code 4C. This is no reason to panic. The advantage of appliances that give you error messages is that each message directs you to what’s wrong so that you can troubleshoot it yourself.

A 4C error means your washing machine is having problems with the water supply. Troubleshooting error code 4C does not require you to contact a professional in most instances. Solutions you could try include checking the water supply, making sure your washing machine can bear the load, and ensuring that the water valves are working.
Check the Water Supply to Your Samsung Washer
If you’re getting a 4C error, it could mean that the water supply to your Samsung washer is faulty. Verify that the water tap is open and running. If it is, make sure enough water is coming out and it is fully open.
Water supply challenges could also result from low water pressure or low flow rates on the supply to the washing machine. In other words, water is not flowing with the required force. A faulty water hose is likely responsible for this.
To check the water hose, turn off the device and then examine the hose for any bends or kinks.
Alternatively, the error code 4C could be the result of a leak. If the hose is leaking because it is
damaged, it might be time to replace it.
Check the Water Connection On Your Samsung Washer
Your 4C error code could be the result of an improper connection. Likely, one of two things are going on here: Either the washing machine hose could be loose or not correctly inserted, or the hose or hose adapter might not be properly connected to the tap.
To fix a loose or incorrectly inserted hose or hose adapter, simply make sure the hose is secured correctly.

Clean Your Samsung Washer’s Water Hose Mesh Filter

A dirty mesh filter could be behind your machine displaying a code 4C error. It is recommended you clean the mesh filter at least twice a year. This can be done in a few easy steps:

- Use pliers to pull out the mesh filters from the water supply intake
- Clean the mesh filters by rinsing them in water
- Reinsert the mesh filters
- Reattach the L-shaped arm fitting in the machine
Clean the machine’s dispenser drawer
A blockage in the detergent drawer could be causing the error code. Here is how to fix this for both manual and automatic dispensers.
Manual Dispensers
- Pull out the detergent drawer while holding down a release lever inside the drawer.
- Remove the softener compartment and the liquid detergent guide from the detergent drawer by lifting them.
- Use running water to rinse everything.
- Use a delicate object to clean the detergent drawer recess. A toothbrush or makeup brush will do.
- If you removed the softener compartment and the liquid detergent guide, replace them by pushing them into the detergent drawer.
- Push the detergent drawer back into place.
Automatic Dispensers
- Pull out the detergent drawer while holding down a release lever inside the drawer.
- Detach the detergent and softener compartments.
- Fill both compartments with water and shake.
- Use a delicate object to clean both cap valves. A toothbrush or makeup brush will do.
- Use running water to rinse everything.
- Clean the detergent drawer recess and cap valves with a delicate object such as a soft brush.
- Replace the softener compartment and the liquid detergent guide by pushing them into the detergent drawer.
- Push the detergent drawer back into place.
Clean Your Samsung Washer’s Debris Filter

There is a filter on the bottom of your Samsung washing machine known as a debris filter. If it is clogged, this could result in an error code 4C message. To clear the blockage:
- Locate the debris filter on the bottom of your washing machine and open the cover. Use a coin to pry open the cover gently.
- Remove the white drain plug and empty the water
- After the water has emptied from the auxiliary drain hose, remove the filter by first turning it counterclockwise, then pulling.
- Use a soft object such as a toothbrush to clean the filter.
- Reattach the debris filter by pushing it in and turning it clockwise until it is secure.
- Replace the cover by placing it in the holes at the bottom of the access panel opening and pushing or folding it into the top.
Avoid Heavy Laundry Loads
The type and volume of laundry in your Samsung washing machine could cause an error code 4C. This is even more likely if you can hear the sound of water filling up, yet the error persists.
You could be loading the washer with too much laundry, or the type of laundry you placed in the device soaks up too much water. Such items include blankets and pillows. Check your user manual for instructions on the amount and type of things you can wash per cycle.
Examine the Water Supply
The water inlet valve controls the flow of hot and cold water in your washing machine. When this component is not working, there might be little to no water in your Samsung washer, causing a 4C error message.
The water supply valve can be located near the hoses. Check if the valve is fully open. If it is not, your machine is not getting enough water, hence the error.
If the valves are damaged, however, it is time to replace them. This can be accomplished in a few easy steps:
- Turn off the water and power supplies.
- Disconnect the cold water inlet hose at the back of the washing machine.
- Remove screws at the back to detach the top panel.
- Remove wires from the cold water inlet valve.
- Compress clamps on the connected outlet hoses so you can wiggle them down from the valve before pulling them off.
- Loosen the two screws located on the outside of the cold water inlet to release the inlet valve.
- Pull out the valve.
- Push the new valve’s inlet through the hole in the back panel and secure it with the two screws.
- Slide the outlet hoses over the two ports and tighten the clamps over them.
- Connect the two-wire harnesses to the correct terminals.
- Slide the top panel along the rails until it is fixed in place before tightening the two screws on the back.
- Connect the cold water inlet hose to the new valve.
- Restart your Samsung washing machine.
