Samsung dishwasher error codes can appear on your digital display screen when there is a problem with the normal operations of your Samsung dishwasher. By understanding the Samsung dishwasher error codes, you can solve any problems that may arise. Models with a digital display will display an error code when something is wrong with a particular part of your dishwasher. Samsung dishwasher troubleshooting is something you can do on your own without being an expert in appliances.
Samsung Dishwasher Error Codes
1E / IE – Water Flow or Filter Error (Common on WaterWall Models)
What it means: Water isn’t flowing properly through the filter, which is often caused by debris buildup.
What you can try:
- Remove the fine filter at the bottom of the dishwasher
- Rinse it under warm water and clear trapped food particles
- Reinstall the filter and run a Normal cycle
Call a technician if: the code returns after cleaning and restarting.
3C – Pump Error
What it means: The dishwasher pump isn’t operating as expected.
What you can try:
- Turn the dishwasher off
- Unplug it (or switch off the breaker) for 5 minutes
- Restore power and start a fresh cycle
Call a technician if: the pump error keeps returning or the unit won’t drain.
3E – High Water Temperature
What it means: The incoming water temperature is too hot for safe operation.
What you can try:
- Ensure your hot water temperature is below 176°F (80°C)
- Restart the dishwasher after the water has cooled
Call a technician if: the error persists even after lowering hot water temperature.
4C / 4E – Water Supply Error
What it means: The dishwasher isn’t getting the correct water pressure or water temperature.
What you can try:
- Make sure the water supply valve is fully open
- Check the inlet hose for kinks, pinching, or restriction
- If your dishwasher is using a flood-safe hose, consider replacing it, since many Samsung units don’t work well with them
Call a technician if: the water supply is on but the dishwasher still won’t fill or the code returns repeatedly.
5C / SC / 5E / SE – Drain Error
What it means: Something is preventing the dishwasher from draining.
What you can try:
- Check the drain connection under the sink (blockages are common)
- Inspect the drain hose for kinks or clogs
- Remove and clean the dishwasher filter
- Check the sump area for debris buildup (where water collects at the bottom)
Call a technician if: the dishwasher keeps holding water or makes unusual pump noises.
7E – WaterWall Reflector Error (WaterWall Models)
What it means: The WaterWall reflector can’t move freely due to misalignment or debris.
What you can try:
- Inspect the reflector and confirm it’s seated in the correct position
- Clean the area around it to remove buildup
- Restart the cycle
Call a technician if: the reflector still won’t move or the code returns often.
9E – Low Water Level
What it means: Not enough water is entering the dishwasher to run properly.
What you can try:
- Remove dishes and run a Normal cycle to test water fill
- Confirm the water supply valve is fully open
- Make sure the inlet hose is not bent or blocked
Call a technician if: the dishwasher still isn’t filling or the code returns.
AP – Access Point Mode
What it means: This is not a fault. The dishwasher is in Wi-Fi pairing mode and is trying to connect to a mobile device.
What you can try:
- Turn the dishwasher off
- Turn it back on to exit Access Point Mode
6E – Button Error
What it means: A button on the control panel is stuck or being pressed continuously.
What you can try:
- Turn the dishwasher off
- Press each button one by one to check for sticking
- Wipe the control panel with a lightly damp cloth
- Turn the dishwasher back on
Call a technician if: the button error keeps returning or buttons don’t respond normally.
How to Reset a Samsung Dishwasher
A reset clears temporary glitches and is worth trying before booking service:
- Turn the dishwasher off
- Unplug it or turn off the breaker
- Wait 5 minutes
- Restore power
- Start a fresh cycle
If the same error code returns after resetting, the problem is likely ongoing and needs repair.
When You Should Call a Technician
Book service if:
- The same code keeps returning after you clean filters and reset power
- The dishwasher is leaking
- It won’t drain, won’t fill, or stops mid-cycle repeatedly
- You hear grinding, buzzing, or burning smells
