Samsung Dryer Error Codes: 6 Explained and easy fixes

When something goes wrong with your Samsung dryer, it sends error messages flashing on a screen. Use this guide on Samsung dryer error codes to help you understand where the trouble might be coming from.

Some of these Samsung dryer error codes are easier to understand than others. They may easily be corrected with a simple step, like closing the dryer door or removing lint from the lint filter. But many of these problems cannot be solved without hiring a professional. Let’s get started and see what you can fix yourself.

Whenever you see an error code on an appliance, the first step is always to power down the appliance and actually unplug it from the wall. Allow the appliance to sit for several minutes before turning it back on. Just like a computer or cell phone, sometimes appliances can have an electrical glitch that needs reset.

Samsung dryer error codes explained

Explained below are the Samsung dryer error codes you might see:

1) bE

The ‘b’ stands for button. ‘bE’ means ‘button Error’.

When this flashes on the digital screen, the dryer is telling you that a button is stuck. You might have pressed a button to hard to too many times and it didn’t toggle back to its original resting position. If the button is still actively pressed, the dryer won’t operate.

Take a closer look at the buttons and its edges and see if it just failed to return to its original position. You can gently use a tooth pick or cotton swab to try and get it into place. If this doesn’t work, you’ll have to remove the access panel or call a technician. It should be a pretty easy and inexpensive fix, unless you have underlying issues.

Always unplug the dryer (and/or turn off the breaker) before attempting any repairs on your appliance. Avoid the risk of electric shock!

2) dO, dE, or dF

The ‘d’ stands for door. ‘d’ error messages means that something is wrong with the DOOR, causing the dryer to not want to operate.

dO or dE simply means ‘door Open’ or ‘door Error’.

You may have forgotten to close it, didn’t close it hard enough, or a clothing item is caught in between.

dF, on the other hand, means ‘door circuit Failure’.

When this flashes on your digital screen, it means that electricity going to and from your dryer’s door is failing. The dryer is telling you there is something wrong with the dryer door’s switch or wiring (harness).

If you are comfortable with removing the access panels, you can check the wiring and the door switch to see if there are loose connections. Otherwise, it’s best to call a repairman.

It may be that either the switch or the harness is damaged and needs replacement.

3) Et

The ‘t’ here stands for ‘technical’. Et means your dryer is suffering from a serious technical error. This ‘Error is too technical’ for the machine to explain and requires a more extensive explanation.

As mentioned above, try to unplug the dryer and wait for several minutes. Then plug the dryer back.

If it returns the same error message Et on your screen, then something in its electronic components has crashed. A brief explanation:

The component that commands the dryer is called the EEPROM (Electrically Erasable Programmable Read-Only Memory). It is the communication center of your dryer, located on the dryers PCB (Printed Circuit Board).

The PCB is where it all happens: orders are received, commands are given, and actions are executed from this place.

When the EEPROM or something in your PCB malfunctions, your dryer’s screen will flash an Et error message.

Your dryer’s PCB needs to be replaced with a new one. Unless you have experience working with appliances and electrical components, it’s a job best left to a technician. Should you attempt to replace it yourself, replacement parts can be ordered online. Always unplug an appliance when attempting repairs!

4) FE

The ‘F’ here stands for frequency. FE means that your dryer is experiencing a power source ‘Frequency Error’. There are two probable cause for this:

1) The place where you live doesn’t have a strong and consistent supply of electricity. This means that the electricity that comes to your house fluctuates irregularly — sometimes it’s strong, sometimes it’s weak.

And when it’s weak, your dryer can tell, because it isn’t getting enough consistent power. It will send you an FE message.

This is not a likely scenario, unless you live in the country or an underdeveloped area. Most likely is cause two:

2) It can also be a faulty power frequency sensor in your dryer.

Your power company may be supplying the needed frequency (60 Hz) but because of a damaged or malfunctioning frequency sensor, your dryer is sending the FE error message.

Contact your repair center right away. They can help you diagnose the real cause of the FE error message, and guide you in what steps to take. Samsung dryer error codes.

5) hE

The ‘h’ stands for ‘heat’. hE means ‘heating Error’.

This means that the heating system on your dryer is not producing enough heat or the heat sensor (thermistor) is not sensing heat accurately.

Whether your dryer’s heater is gas or electricity powered, have your repairman check for any of these faults. Although unlikely, the problem may be caused by a fault in the gas supply, which limits the supply to the heater coils.

Make sure the cut-off valve for the gas supply is fully open.

In case of electricity powered, your repairman will first check if your dryers circuit breaker is closed.

If it’s open, no electricity will flow to the heater. But then he’ll have to find out what electrical problem trips the circuit breaker. If it’s faulty or damaged wiring, then he’ll replace that, too. Also, if the fault is with the heat sensor, the repairman will replace it.

Summary: if your Samsung dryer fails to generate heat, it is predominantly attributed to a burnt heating element, accounting for 80% of the cases — while the remaining 18% are caused by a blown thermal cut-off fuse, cycling thermostat, or a failed control board heater relay. The remaining 2% may stem from an inadequate power supply, whereby the dryer receives only 110 Volts, instead of the required 240 Volts.

6) oD

‘oD’ means ‘over Dry‘. When this happens, it may indicate that the dryer didn’t sense that the clothes were already dry.

Either the moisture sensor malfunctioned or something was causing it to misread the moisture level inside the drier. If a moist object or film is stuck on the sensor, it might think that the dryer tub still has a lot of moisture.

This could make it send an inaccurate oD error message. Check the moisture sensor and wipe it dry. If the oD error persists, call in your repairman. Your dryer might need a new moisture sensor. See image below.

Moisture sensor replacement bars are available on Amazon starting at about $6. Be sure to double check your model number for compatibility when ordering. Click here.

The article below has extensive information on replacing moisture sensors and other technical tips.

If the thermistor registers a normal resistance (10,000 ohms) reading, then the error message is probably due to some faulty or damaged electrical wiring. Contact a repair technician for additional help on electrical components.

Knowing how to read and understand these Samsung dryer error codes will also help you understand your dryer issues better. This can help the repairman troubleshoot faster and get your dryer up and running again.

  1. I have a samsung DVG50M7450W/A3. It powers on the screen but wont turn on when i press the start button yet it starts to count down as if its working. When i hold down the dry level button along with the adjust time up button it gives me a code. 1n5. I dont know what this is. Thanks for any help.

  2. We have changed the complete heating element, with fuse and thermosister. It keeps blowing, we can’t get the hour glass to go away even after loads are finished, and the only code I can get is 5C, or SC… Not sure which one it’s supposed to be any ideas?

  3. My Model: DVG60M990V/A3 is showing code HC2 will reset when we turn off but code randomly appears and shuts down the cycle??? Any suggestions?

  4. Samsung dryer … My dryer all of a sudden is showing a “moving” square. I’ve cleaned the sensor button on the inside of the dryer and I have unplugged the dryer for 10 min. There is no lint in the dryer nor up the tube leading to outside. Dryer still dries the clothes but at the end of the cycle it shows a moving square. What is the reason for this?

  5. My Samsung Elect Dryer/ DV42H5200 stopped during cycle. The error code dE, we cleaned off inside door, unplugged for over an hour, check panel box. We cleaned out dryer hose vent/ the inside filter very clean, but vaccumed anyway. Still nothing. The power switch lights up, and we can choose cycle, but when push start, nothing happens.
    HELP? Suggestions??

  6. City drains overloaded last night and we had about 6-8 inches of water. Dryer was not running. Had water exposure at vent. 3C was blinking.

  7. My Samsung Dryer model DVE22K6500V/AP has an error code C90. This appears everytime I run the diagnosis. I already replaced the power cord and nothing. Also, it doesn’t heat and the time jumps from 30, 29, 28, 27 and then to 1 minute and stops. The clothes are not dried at all. Thanks.

    • Do clothes warm by touch when it finished? If not, then there is a problem with the heating element or thermal fuse. If yes, then check moisture sensor wires, to make sure they are not corroded or oxidized . Also, check dryer vent line from the dryer to the outside.

  8. My Samsung dryer has a blinking shirt and arrow code. The timer is counting down like its running, but it’s not.

    • Turn the drum by hand clock-wise. Is it turning easy without resistance? If yes, you have failed drum belt or tension roller
