13 Common Samsung Dishwasher Error Codes

samsung dishwasher error codes

The below error codes give you the right explanation and at the same time helps you diagnose the problem. Read further to know what they are.

1. Error Code: 1E

  • Condition: When the dishwasher detects high temperature heat error or the water doesn’t drains properly, it displays the error code 1E.
  • Check: Filter system, drainage and pressure switch

What To Do?

A very common Samsung dishwasher error code is none other than 1E. According to user manual, this occurs due to high heating error. However, improper drainage could also be a reason. Hence, you need to check both the things for this. Low, Abnormal or Normal W/L Frequency Level is usually 30.00 Khz whereas High Level is 15.00 Khz. If you are not aware as to how to check or fix this, we advice you take the help of a technician. However, if you are sure that it isn’t the pressure switch and it is the blockage that is preventing the system from draining properly, then you can fix it by cleaning your sump and filter system. To do this, follow the steps given below:

Warning: If your dishwasher was running fine, then just open its door and let it cool prior completing the given instructions.

  • First, open your dishwasher’s door and find the filter assembly.
  • Rotate your filter handle (in counterclockwise direction) to unfasten the compartment door.
  • Next, take away the filter door and take out the micro filter beneath.
  • Remove dirt/debris from your filter door and micro filter.
  • Rinse thoroughly using water.
  • Check the sump and clean it.
  • Reinstall the micro filter and filter door.
  • Finally, rotate your filter door handle (in clockwise direction) to lock it.

Note:

  • For best performance, always clean your sump and filter frequently.
  • If your filter door isn’t closed correctly, cleaning performance may decrease.

2. Error Code: 3E

  • Condition: When there is a motor restriction, your dishwasher displays the error code 3E.
  • Check: Washing motor

What To Do?

For every 500 ms, your Hall Sensor is been sensed (this is right after your motor starts).
If the data of hall sensor is below 2RPM, then the washing motor immediately stops. This is exactly when the Samsung dishwasher shows the error code 3E. Restarting the machine usually fixes the problem. However, if this doesn’t fixes, it is better to contact customer support.

3. Error Code: 4E

  • Condition: When the dishwasher does not detect water inside the tub for about 5 minutes, it shows the error code 4E.
  • Check: Water inlet valve

What To Do?

This Samsung dishwasher error code means that there is a fault in “water supply”. When you get this error code, check the water supply valve first (which is typically below the sink). Ensure that your valve is turned on. Next, ensure that you have proper valve pressure (between 20 psi and 120 psi) on the DW. To do this, unplug the Samsung dishwasher and turn off your water supply. Disconnect the fill line and inspect the water inlet valve properly. Now, if your inlet screen is blocked, change the water valve—do not just clean it’s screen because dust particles can enter and thereby, causes flooding. Also, check the wire connections of the inlet valve. Secure the loose connections if any. If the valve does not open even after doing all these, replace it.

4. Error Code: 4E1/HE1

  • Condition: When the water entering the Samsung dishwasher is above 176°, it displays the error code 4E1 or HE1.
  • Check: Main PBA (Power Board Assembly) and thermistor

What To Do?

Test the temperature of hot water from your kitchen’s valve. If it exceeds 120°, try lowering the water heater. If it is below 176°, the temperature sensor (or thermistor) is defective. It is better to replace your thermistor. If this doesn’t fixes the issue, change the main PBA.

5. Error Code: 5E

  • Condition: When the dishwasher doesn’t drains water, it displays the error code 5E.
  • Check: Drain hose and Drain pump

What To Do?

5E is probably one of the most common Samsung dishwasher error codes. If you get this error, look for the air gap at the top of your sink. Try to clean this first. It is quick and simple to do. Just remove the cap and clean the debris from inside. If it is dirty, you have saved yourself a lot of work. It is the simplest way to check for 5E error.

Next, you can unplug your dishwasher from the socket and then clear all the clogs from drain pump as well as drain hose. If these two parts are damages, it is better to replace them. Once you have cleaned them, turn on your dishwasher and see if it drains. Frequently, debris clogs the connection below the sink. So, cleaning it should fix the problem.

Samsung dishwashers usually use a secondary drain pump. This drain pump is separate from the assembled wash motor and is mostly on the right side. Sadly, the dishwasher needs to be removed to verify the pump. The secondary drain pump is of 110v with a tiny impeller at the inside. Small things like seeds, glass etc, can make it all the way through pump housing. Once gathered, they jamb the pump impeller. To fix this, first ensure that you have disconnected the power supply. The auxiliary or secondary drain pump is then mounted to the assembled plastic sump with the help of a locking tab. Now, depress the tab and then twist the drain pump housing. Hope this fixes the issue.

6. Error Code: 8E

  • Condition: When the dishwasher detects excess current supply, it displays the error code 8E.
  • Check: MEM sensor and appliance’s wires

What To Do?

The Samsung dishwasher’s motor is controlled by IPM (Integrated Power Module). A fault signal is displayed by the IPM if there is a power overload. If the error (low signal) is sensed during the washing or rinsing phase, the motor stops right away. This is exactly when the error 8E is displayed. When this happens, try switching off your dishwasher and turn it on again to clear out the overload problem. If the problem still persists, it is better to contact customer support.

7. Error Code: 9E

  • Condition: When the dishwasher detects low water level, it displays the error code 9E.
  • Check: Water level and wire harness

What To Do?

One of the commonly occurring Samsung washer error codes is none other than 9E. If you have been googling around for a proper answer to this code, here is what you should do. Make sure that the water hose and the sensor is clean and clear, as in – free from food debris. Start the cycle again. Adjust the water level of the dishwasher if it is incorrect. Reconnect loose wires (if any) on the wire harness. Also, check if the wire harness is damaged. If yes, replace it. If the connections of wire harness are ok, just replace your water level sensor.

8. Error Code: 11E/LE/LE1/E9

  • Condition: When the dishwasher detects water leakage, it displays the error code 11E/LE/LE1/E9.
  • Check: Drain pipe and hose

What To Do?

One of the most common Samsung dishwasher error codes is 11E/LE/LE1/E9. Water Leakage occurs when the water drains off naturally (which is right after the washing process starts). If you get this error, check if there is any water leakage below the dishwasher. Also, inspect the drain pumps, tub and hoses. If you find any leaking parts, replace immediately.

At the bottom, where water fills up, you will see a sensor. Today’s dishwashers usually have this sensor to cut down water damage. The 11E/LE/LE1/E9 error code denotes the sensor present at the bottom. If you are trying to fix this, the toughest part is to take away the dishwasher below the counter. Based on the electrical wires and water line hooked up, this could take somewhere from 5 minutes to 2 hours. Hence, if you are unaware as to how it is fixed, do not try anything, as you may end up messing up further. However, if you are ready to take this job, then your dishwasher needs to be laid on its side or on its back. Keep the dishwasher on a thick towel or a blanket because water will leak out. In the bottom, you will see a tiny screw and few plastic tabs, which holds them together. You need to remove them. Once done, figure out from where the water is leaking. Mostly, it should be from your motor or hose. Try sealing it.

9. Error Code: 0E

  • Condition: When the dishwasher detects over flow, it displays the error code 0E.
  • Check: Main PBA (Power Board Assembly) and water inlet valve

What To Do?

Next on the list of Samsung dishwasher error codes is 0E. This is displayed when your dishwasher detects high water level. This can be easily cleared. Just unplug your dishwasher or turn off the circuit breaker for the Samsung dishwasher to disconnect electricity. If the water persists to fill the tub, change the inlet. However, if the water filling stops, replace the main PBA (power board assembly).

On the dishwasher’s left side, you will see a small plastic box, in which there is a sensor. If the box is clogged with food particles, it slows or stops the further water flow. Now, when this thing happens, the error code 0E is displayed. However, if the sensor box is blank, it needs to be replaced.

10. Error Code: HE

  • Condition: When the dishwasher detects heater failure, it displays the error code HE.
  • Check: Main PBA (Power Board Assembly) and heater

What To Do?

HE is yet another common Samsung dishwasher error code, which is displayed when there is a heater failure. You can fix this by unplugging the dishwasher first and then check for heater’s wire connections. If it is damaged, it is wise to replace it. However, if it is fine, just change the main PBA (Power Board Assembly).

11. Error Code: HE1

  • Condition: When the dishwasher detects heater failure, it displays the error code HE.
  • Check: Main PBA (Power Board Assembly) and heater

What To Do?

HE is yet another common Samsung dishwasher error code, which is displayed when there is a heater failure. You can fix this by unplugging the dishwasher first and then check for heater’s wire connections. If it is damaged, it is wise to replace it. However, if it is fine, just change the main PBA (Power Board Assembly).

12. Error Code: bE2

  • Condition: When the control board detects shorted or stuck key on the touch pad, it displays the error code bE2.
  • Check: Control panel

What To Do?

To fix this, you need to press all the buttons on the control panel to free the stuck key. This usually helps over the problem. However, if the button remains stuck, call customer support. Chances are that they might ask you to replace the control panel if it is damaged.

13. Error Code: PE

  • Condition: This is a half-load error.
  • Check: Distributor motor assembly

What To Do?

To fix this Samsung dishwasher error, you need to unplug and reconnect the loose wires on the micro-switch and distributor plate motor (replace it if required). If you are sure that the wire harness is damaged, it is better to replace it.

Note: Once you get an error on your Samsung dishwasher, it is important to refer the user manual. However, if you don’t have it, you can download from Samsung Download Center.
