Fixing your 4C Error Code Issues
If your Samsung Washer shows a 4C or 4E error code, don't worry! Several factors could be causing the issue, and many fixes are simple and cost-effective. Continue reading to find out how you can fix the 4C/4E error on your own without the need for expensive repairs or replacement parts.
How to Resolve a 4C Error on a Samsung Washer
If your Samsung washer displays a 4C or 4E code, it means the machine has detected a problem with the water supply. This could be caused by a temporary glitch, low water pressure, a clogged detergent dispenser, or a blocked or kinked main hose.
Instructions
Possible control board issue.

Reset the washer. The error could simply be a temporary glitch with no actual fault in the machine. Resetting your washer will clear this up:
- Unplug the washer and wait for 5 minutes before reconnecting it to power.
- If the 4C or 4E code appears again after restarting, further troubleshooting may be needed.
Clogged detergent dispenser.

Clean the detergent dispenser. Overusing detergent (or using non-HE detergent) can cause clogging, resulting in weak or overflowing water flow. This could trigger the 4C/4E error. Here's how to clear the blockage and fix the issue:
- Ensure the washer is off and unplugged.
- Remove the detergent dispenser drawer, using the lever inside the drawer to make removal easier.
- Disassemble the drawer into its two sections: the softener compartment and the detergent section.
- Clean the parts with warm water.
- Use a tool like a toothbrush to clean hard-to-reach spots inside the washer.
- Once everything is clean and dry, reassemble and insert the drawer back into the machine.
- Run a "Rinse" cycle without any laundry to finalize the process.
Low water pressure.

Ensure your water pressure is adequate. If your water pressure falls outside the 20-120 psi range, the washer will display a 4C or 4E code. To check your water pressure:
- Move the washer away from the wall to access the main water supply valve. Use a towel to catch any drips.
- Disconnect the valve from the hose.
- Attach a pressure gauge to the valve and open it fully.
- Ensure the gauge reading is within the 20-120 psi range.
- If it's cold outside and your pipes are uninsulated, frozen or burst pipes could be the issue. Contact a plumber immediately to address frozen or burst pipes, which could resolve the 4C/4E code on your washer.
- Alternatively, you can contact your utility company to inquire about your water pressure.
Water tap not fully open.

Fully open the water tap. If the valve isn't completely opened, you may face water pressure issues. Here's how to open it fully:
- Unplug your washer and move it away from the wall.
- Turn the water tap counterclockwise until it's fully open.
- Plug the washer back in and check if the error code is gone.
Clogged or kinked water supply hoses.

Inspect and clear the inlet hoses. A blocked or bent hose connecting the water supply to your washer can reduce water flow, triggering the 4C or 4E error. Here's how to clear the hoses:
- Unplug the washer and turn off the water supply.
- Pull the washer away from the wall.
- Check the hoses for any kinks or blockages.
- Place a towel on the floor to catch any leaking water during the cleaning process.
- Remove the mounting hardware that holds the hoses in place.
- Disconnect the hoses from the water valves.
- Inspect the hoses for obstructions. Use high-pressure water or a long brush to remove any blockages.
- Reconnect the hoses to the water valves and washer, then turn the water back on.
- Check for any leaks during this step.
- Plug the washer back in and run a short cycle to verify that the error code has been resolved.
Clogged mesh filters.

Clean the mesh filters. A clogged mesh filter can restrict water flow, leading to the 4C/4E error. Make sure to clean them twice a year for optimal performance.
- Turn off the water supply to the washer.
- Place towels or a bucket to catch any water that may spill during the cleaning process.
- Disconnect the water hoses from the back of the washer.
- Locate the mesh filters inside the valves.
- Use needle-nose pliers or a small tool to remove the mesh filters.
- Clean the filters with warm water or a toothbrush.
- If the filters appear damaged, replace them with new ones that fit your Samsung washer model.
- Reinstall the filters and reconnect the hoses to the washer.
- Turn the water supply back on and run a short cycle to check if the 4C/4E code disappears.
Faulty water inlet valve.

Replace the water inlet valve. The water inlet valve controls the flow of water into your washer. If it fails, the washer won't get water, triggering the 4C/4E error. Here’s how to replace it:
- Unplug the washer and turn off the water supply.
- Move the washer away from the wall to gain access to the back.
- Place towels on the floor to absorb any water that may spill.
- Disconnect the hoses from the back of the washer.
- Unscrew the back panel to expose the water inlet valves.
- Disconnect the wires from the faulty inlet valve.
- Remove the screws securing the faulty inlet valve and take it out.
- Install the new inlet valve in the same spot and secure it with screws, then reconnect the wires.
- Reattach the back panel and screw it back into place.
- Reconnect the hoses to the washer, then run a short cycle to ensure the 4C/4E error is resolved.
