Samsung Fault Codes

Samsung washing machine fault codes

These are probably the most common fault or error codes used in Samsung washing machines and most of them use the same fault or error codes when the washing machine has a problem or a spare part fails. These particular codes are used on later models from about 2006 or so onwards.

These fault codes for Samsung washing machine and washer dryer models will displayed as a digital code, exactly as you will see below, in an LED or LCD panel or display on the front of the washing machine.

Before you start any investigation of the fault or even remove the lid of your Samsung washing machine or washer dryer please read and fully understand this article in full and pay particular attention to the safety and information notices at the bottom of this page as they contain extremely important information!

Please remember to support our site and our ability to publish fault codes, provide support and so on by buying Samsung spares from our spare part store and, if you decide that you need an engineer please support the local repairers that help make this site possible, you can find an engineer using the engineer search facility.

  Samsung Washing Machine Fault Codes

Like other fault codes these written for washing machine repairers and not for the general public by Samsung and UK Whitegoods and they assume a certain level of competence on the part of the user in diagnostic routines. We have added some notes to try to assist you in determining the nature of the fault you have but, you will still need to investigate each failure on its own merits. For more help and advice on fault finding on a washing machine please refer to our washing machine fault finding guide from this link before you begin.

Therefore while these error codes give you a clue as to what the problem might be as well as what to look at they will not pinpoint an exact point of failure nor will they tell you how to repair your Samsung washing machine.

Please check that any Samsung washing machine spares recommended are suitable for use on your particular model and production code or serial number. If you are unsure about the suitability of any spare part please ask to ensure that you get the correct spares for your washing machine.

Please, don't guess or assume as spares can be altered on a production run with the same model number having several different alternative components used.


Washing machine has failed to drain the water

If water level frequency is still lower than the reset level frequency (25.20kHz) in 10 minutes after starting of water drain, this error will occur.

This error code is very common and can be read as being either "SE" or "5E" due to the digital display as we are often asked what either could mean, they are the same code.

This error will be released using Start/Pause button, the washing machine will restart and attempt to drain the water out again.

  • Check pump filter is clear and there are no obstructions
  • Check the drain hose for obstruction
  • Check the drain hose is not kinked
  • Check the drain pump filter and clean if required
  • Check the air chamber and pressure sensor hose
  • Check drain pump
  • Check drain pump rotor
  • Check connections to water drain pump

If the pump is faulty then ask us about it as there are low cost compatible pumps for Samsung that can be less than half the price of a Samsung part, for the same component.



Water fill time out

The washing machine has failed to fill with water in a reasonable time.

If there is no higher change in water frequency than 100Hz for 2 minutes during the initial time of water supply and if water level doesn't reach the preset level in 10 minutes, this error will occur.

This error will be released using Start/Pause button, the washing machine will restart and attempt to fill with water again.

  • Check water supply is on, clear and not frozen
  • Check the air chamber and pressure sensor hose for blockages
  • Check water inlet valve
  • Check wiring to water inlet valve
  • Check connections to water inlet valve
  • Check the main control PCB



Washing machine door detected as being open

  • Check door is closed correctly and latched
  • Check door handle for damage or wear
  • Check door safety lock if inoperative replace door lock
  • Check door lock wiring



Washing machine has detected an imbalanced load

This error code is more for information purposes than actually a fault as such. What the washing machine is telling you is that it has been unable to sort the laundry load and correctly spin without a risk of damage due to an unbalanced load. This error will clear when you restart the machine but do sort the laundry reduce or increase the load as required and for more information on load imbalances please see this article.

  • Reload the washing machine and attempt to spin again
  • Check the installation of the washing machine for level and balance
  • Check for small loads as small loads will cause an imbalance error



Motor tacho fault detected

Can also be caused by be main PCB

If the motor tacho signals are inputted less than 2 for 2 seconds after main drive motor started, this error will occur.

  • Check motor
  • Check motor tacho
  • Check all connections and blocks to the motor
  • Check connections on the main control module
  • Check main control module



Motor triac short error

Can be a short circuit to motor or PCB

If the motor tacho signals are inputted more than 300 every 1sec in the operational interval less than 90RPM, this error will occur.

  • Check mains supply
  • Check main control module
  • Check main drive motor



Washing machine has detected an overfill situation

This error code can be caused by overfoaming which is a result of overloading (see this article) or by overdosing or, incorrect detergent as the pressure sensor will falsely read that there is too much water in the washing machine.

Also check the pressure sensor and that the machine has not actually overfilled with water.

If an abnormal water level frequency is sensed (for occurrence of Over Flow :21.00kHz), Auto Power Off may release this error and continuously progress water drain until the frequency reached 25.00kHz.

If Over Flow is also sensed even after the following check of water level frequency indicating that error, the washing machine will attempt to drain the water from the tank.

  • Check for overfoaming or over soaping
  • Check the air chamber and the pressure switch hose
  • Check water level sensor
  • Check wiring to water pressure sensor
  • Check connections to water level sensor
  • Check main electronic controller



Water leak detected

If more than 4 times of water supply and safe water level of Heater are sensed for each course, this error will occur.

  • Check for any water leaks



Water heating error detected

For this error code you need to check both the water heater or element and thermistor, basically the washing machine is reporting a fault on the heating circuit with this fault code but it is not capable of identifying exactly where the fault actually lies.

This error will be released by turning off power switch.

Display : “HE1"(Over Heat), Display : "HE2", indicating no operation of the heating element.

  • Check water heating element 
  • Check heater for contunuity
  • Check thermistor or temperature sensor
  • Check the thermistor resistance
  • Check wiring to water heating element
  • Check connections to water heating element and temperature sensor



Water heating sensor error detected

If thermistor circuit is abnormal, this error will occur. If the thermistor is lower than 0.2V or higher than 4.5V, this error will occur. This error will be released by turning off Power S/W.

  • Check thermistor or temperature sensor
  • Check the thermistor resistance
  • Check wiring to water heating element
  • Check connections to water heating element and temperature sensor



Water level sensor fault

This fault code is fairly self-explanatory and tells you that the washing machine has detected an error with the pressure sensor or pressure switch.

If the above frequency signals are displayed longer than 5 seconds, it indicates pressure switch fault.

The washing machine will drain the water for 3 minutes for this error, and turn OFF water drain pump.

  • Check water level sensor
  • Check wiring to water pressure sensor
  • Check connections to water level sensor
  • Check main electronic controller



Abnormal water temperature detected

Water drain begins if abnormal water temperature is sensed at the initial time of water supply. If the frequency higher than 25.20KHz is sensed, water will be drained by force.

  • Check thermistor connections
  • Check thermistor


  Get Samsung Washing Machine Parts

Getting the correct spare part to repair your Samsung washing machine can be very confusing as there are many variants, even with the model number it is sometimes the case that a serial or production number will be required to ensure that you get the correct spare part.

Apart from that there are often lower cost compatible spares available that we may be able to recommend that can offer you a considerable saving.

We recommend that you contact us with the model information and we will give you guidance on pricing, availability and any lower cost alternaives that can be used. Simply fill out the form below and we will get back to you quickly.

  More Samsung Washing Machine Help

Should you need more help and guidance please use the links from this article as most of them will help you to understand your Samsung washing machine a lot better and probably very much help you in diagnosing the fault you have. Of course there are many other articles on the site that will also help you do this.

In addition you can post in our washing machine forums after registering but please do pay heed to the information below before doing so and read the guides, they are there to help you. But if you are in any doubt at all or don't think you are up to diagnosing the fault yourself please use the engineer search to find a local washing machine engineer.

You must understand certain things before you begin or attempt any repairs on your own and we want to make these points very, very clear to anyone that decides to investigate one of these or any other washing machines:

  • We are not responsible for your safety, you are and by using this guide you accept that and accept that any damage that you may cause and work undertaken is entirely at your own risk.
  • We will advise the common causes of the fault codes but we cannot guarantee that any parts or work recommended will resolve the issue. It is entirely your responsibility to diagnose your particular problem and resolve it.
  • We are not responsible for you buying spares that do not resolve the problem, this is down to your own diagnosis not ours.
  • No warranty is inferred, implied or given.

You also have to recognise that fault or error codes are not a "magic bullet", they will not tell you eaxctly what the problem is nor the exact component that may have failed, they will only offer you an indication of where the problem lies and they are no substitute for diagnostic skills. You can find out more about what fault codes actually tell you in this article. So please be well aware that, even with this new found knowledge you will still have to actually be capable of investigating and diagnosing the problem and this means adhering to basic appliance safety for working on them.

Please do note that manufacturers can and do change fault codes without notice and we cannot guarantee that these error codes will apply to your particular model as all codes apply to a wide range of appliances and not normally any one specific model. To determine if these fault codes do apply to your particular Samsung washing machine model please post a request to confirm this in the forums.

hi machine wf b1456gw
machine turns on and fills then stops with no fault code, any clues?

cycle stopping no code
HI Senan, your query is over a year old now, but this reply might help others. Samsung have a known fault on their eco bubble machines. Not mechanical, but the motherboard for some reason does not throw up a fault code, the machine just stops working mid cycle. Lots of turning off, re setting, turning back on again and you might be lucky and get your load of washing out the machine relatively dry enough to put on the line. Samsung are not honouring the 5yr extending warranty (which was the reason I purchased my machine, eco bubble just 5 months over 2yrs old. They say the machine wasnt registered. It was and I have copy of registration. But, having argued till blue in the face with their customer services, I have now purchased an out of warranty insurance policy at £149 GBP which should get me an engineer to at least try and replace the motherboard. I could do it myself to be honest.... but I dont want to risk life and limb trying to pull the machine out. Also, NEVER EVER MESS WITH ELECTRICS/ELECTRONICS if you are not qualified to do so. Risk to life if you do. Anyway, sorry for the ramble, could have made it shorter. But this has been therapeutic writing down how nonsensical warranties are. But a cheap machine and accept that it might not last as long as a £500 one, but my last Zanussi, cheap as chips, lasted me 16yrs and that was with husband and 3 teenagers living at home. Price is not quality. happy New Year.
Hi Senan,

No but if you ask in the forums someone may well know what it is.
