If your Samsung washing machine displays the 4C error code, it indicates an issue with the water supply. This problem can occur due to several reasons, such as closed water taps, faulty water hoses, blocked mesh filters, a dirty detergent tray, or low water pressure.
Follow these steps to resolve the issue:
- Ensure the Water is Turned On:
- Verify both hot and cold water taps are fully open.
- If only cold water is needed, use a Y-connector to connect the hoses.
- Check the Water Hoses:
- Turn off the power supply.
- Pull the washer away from the wall to access the hoses.
- Inspect for kinks or bends and reposition if necessary.
- Tighten any loose connections.
- Clean the hoses by disconnecting them and running water through to check for blockages.
- Inspect the Mesh Filters:
- Remove the mesh filters located where the hoses connect to the washing machine.
- Clean any dirt or debris from the filters and reattach them.
- Clean the Detergent Tray:
- Remove the tray and clean it with hot water and a cloth or brush.
- Use high-efficiency (HE) detergent to avoid clogging.
- Test the Water Pressure (Optional):
- Use a pressure tester to ensure the water pressure is at least 20 psi.
- If the pressure is low, contact a plumber for adjustment.
- Reset Your Washer:
- Turn off the power for a few minutes, then turn it back on.
- Check if the 4C error code has cleared.
If the error persists after these steps, seek assistance from a qualified technician.
