Samsung Dishwasher Error Codes: What Do They Mean?

Image

Having a smart dishwasher that can display error codes can be a lifesaver. They help you diagnose precisely what is wrong with your dishwasher when it acts up. It is important to remember that only Samsung models with a digital display will be able to display the error codes we have listed below. If your dishwasher does not have a digital display, it will show the error code via blinking lights instead.

 It is important to make sure you perform the correct troubleshooting before you attempt to reset the dishwasher or clear the code. If you simply restart it to remove the code, then the issue that has caused the error will not be addressed. 

Error code OE/OC/0C/oE

This code indicates a water overflow error. It shows when there is too much water in the dishwasher, and it may mean there is an issue with the water inlet valve or main power board assembly.

To troubleshoot these issues, you should inspect the drain hose, sink connection, filter, sump pump, and drain. Ensure you clean any blockages thoroughly. If the error continues, you may need to replace the inlet valve or power board.

Error code 1E/IE

This code indicates a clogged filter error. This code means there is an issue with water not passing through the filter. To troubleshoot these issues, clean the fine filter and check for any damage. It is located at the bottom of your dishwasher. If the error code shows up again after you have cleaned the filter, contact a Samsung technician.

Error code HE

This code indicates a water heater error. It means there is an issue with the dishwasher’s ability to heat water. Start by checking the heater’s wire connections and main power board assembly. You may need to replace the water heater if it is damaged or faulty. If the heater is not the problem, check for issues with the main power board.

Error code HE1

This code indicates a thermistor error. This code means that the temperature inside of the dishwasher is higher than 80C. A common reason for this error is that the heater relay on the main power board is stuck. Another issue may be that the thermistor is defective and needs to be replaced.

Error code flashing “Heavy”

This code indicates a water leak. When the word “heavy” is flashing on your digital display, it means there is a water leak. To troubleshoot for this error, you will need to inspect and tighten or replace the drain hose.

Error code LC/LE

This code indicates a water leak error. This indicates there is a water leak under the dishwasher because the drain hoses or pump are faulty. Inspect the hoses, drain pump, and tub thoroughly. You will need to replace any damaged parts.

Error code bE2/BE

This code indicates a control panel button stuck error. It occurs when one or more of the buttons on the control panel has gotten stuck. The easiest way to troubleshoot this error code is to press all the buttons individually to find and unstick the problematic button. If the issue continues, you may need to replace the control panel.

Error code CE

This code indicates a communication error. The error occurs when the control panel is not communicating properly with the dishwasher. To troubleshoot this error, you will need to reboot the control panel. Do this by turning off the dishwasher and restarting the machine. If the problem continues and the error shows up again, contact a Samsung technician.

Error code PE

This code indicates a half-load error code. This code indicates there is an issue with the sump pump, diverter assembly, or motor assembly. It occurs most often when the inner spray arm (which is controlled by the diverter assembly) is not responding. This is most common in the half-load mode. To troubleshoot this issue, you will need to inspect and reconnect any loose wires. You should check for damage and replace all damaged parts.

Error code 3C

This code indicates a Pump Operation Error. This error means the water pump is not working correctly. The easiest way to troubleshoot this error is to reboot your dishwasher. You can do this by turning it off at the power source and waiting 15 to 20 seconds. Then restart it and see if the error has cleared. If this does not work, you should consult an expert as it may need to be replaced. 

Error code 3E

This code indicates a high-temperature error. This code means the water temperature is too high in the machine. To troubleshoot this error, you should start by checking the water temperature setting and confirm it is set below 79c. If the setting is correct, then you will need to consult a Samsung technician.

Error code 4C/4E

This code indicates a water supply error. This code will be displayed if there is no water in the dishwasher tub six minutes after the cycle starts. This code often indicates a problem with the water inlet valve. In order to troubleshoot this, you need to check that the water supply cut-off valve is open fully. Next, check the inlet valve screen is not clogged or damaged. Also, check all wiring, ensuring it is not damaged and that the valve is connected properly. You may need to replace the water inlet valve if the issue continues.

Error code 5C/5E/SC/SE

This code indicates a water not draining error. This code means the water is draining too slowly or not at all from your dishwasher. To troubleshoot this error, you will need to inspect the sink connection, drain, drainage hose, filter, and sump pump. If any of the components are clogged, you will need to clean them thoroughly. If the issue continues, you may need to replace any damaged parts. 

Error code 7E

This code indicates a waterwall reflector error. This error occurs when the waterwall reflector is blocked, or it cannot move. To troubleshoot for this error, check that the reflector has been installed properly. If your machine is new, ensure all the packaging tape has been removed, as this is a common cause. 

Error code 9E

This code indicates a low water level error. This error occurs when there is not enough water in the dishwasher. The best way to troubleshoot this error is to ensure your dishwasher is level and all wires are undamaged and securely connected. You may need to replace the water level sensor or wire harness if they are damaged.
