SUD error in Samsung washing machine

sud errorIf once again you threw the laundry into the drum of the washing machine and started the program, and the Samsung machine stopped a few minutes later, showing the SUD code on the display, then do not rush to call somewhere. After reading everything to the end, you will surely find the reason for the occurrence of this situation, perhaps fix it yourself. First things first.

Error value

Those who are fluent in English may well understand what the SUD error informs the user about. These three letters are taken from the word SUDS, which means soap foam. It is not difficult to guess that this code did not appear by chance, but because there was too much of this foam in the machine. In more detail, this error means that the washing machine has switched to the mode of eliminating large foam formation in the drum. Just for everything, she stopped for 5-10 minutes so that this foam settled, and then the washing process continued.

Not all Samsung washing machines have a Sud error, but this does not mean that nothing happens with increased foaming. It's just that in different models of washers, the codes for the same error are different. Codes 5d and Sd are an analogue of this error, this is one and the same because the number 5 and the letter s are not distinguishable on the small display of the equipment.

Note that even without knowing the exact decryption of the code, you can understand the reason for the machine to stop, if you carefully look at the drum. You cannot fail to notice a large amount of foam.

Reasons for the appearance

On Samsung washers, the sud error can be caused by various reasons. The main one is related to the powder. The reason is as follows:

foam in the drum

  • use of powder not intended for an automatic machine. The fact is that defoamers are added to special powders of the machine, and there are no defoamers in handwash powders, therefore they can not be poured into a washer;
  • fake low quality powder;
  • powder dosage exceeded. If things are voluminous it is better to reduce the norm of detergents, or use a special powder. And if the powder is concentrated, then it generally needs to be strewed strictly according to the dosage.

If the powder you use is beyond doubt, then the whole point is the malfunction of the washing machine. These malfunctions include:

  1. foam sensor breakdown;
  2. breakdown of the pressure switch;
  3. partial blockage in the elements of the drainage system (hose, pipe, sewage);
  4. control board failure, which is extremely rare.

What to do yourself, and with what to turn to the master?

You can fix most of the causes of the Sud error yourself. The most important thing is to act consistently. First of all, wait until the washing machine itself tries to remove the foam. If the error is still displayed, then do the following:

  • press the power button, then de-energize the machine;
  • open the drum and remove the laundry;
  • the door can be locked, then drain the water from the tank through an emergency drain at the bottom of the machine or through a filter;

    Be careful, prepare rags and a flat container in which you will pour water.

  • rinse the drain filter and run an idle (without laundry and powder) program with heating water to 600C to wash the remaining powder from the machine.

If during this mode the sud message reappears, then with high probability it is possible to speak of a breakdown of the foaming sensor. It is not in all washing models, but in some machines its function is performed by a water level sensor, which is often called a pressure switch. The foaming sensor cannot be repaired; it must be changed. With this problem, you should contact the master, who will find the necessary similar part and install it correctly.

If the pressure switch breaks down, you can do the repair yourself. This detail changes quite easily, you need:pressure switch replacement

  1. disconnect equipment from communications;
  2. remove the upper case cover;
  3. find a water level sensor in the upper corner of the washer;
  4. remove the duct;
  5. disconnect flash drives with wires;
  6. connect a new part;
  7. assemble a typewriter.

In some cases, the system may generate a Sud error if the foam does not leave the drum due to partial blockage in the hose or drain pipe. These parts must be cleaned. The drain hose is disconnected from the machine and the cleaning cable is cleaned. To flush the pipe, you need to get it out of the machine. You can do this through the bottom of the washer, you need

  1. put the equipment on its side;
  2. if there is a bottom, remove it carefully;
  3. unfasten the clamps on the nozzle that hold it on the tank and pump;
  4. rinse part and return to place.

Perhaps after cleaning the pipe you need new clamps, they usually change.

As for the "brain" of the machine, or rather the electronic board, we always recommend that you contact the master with this problem. Both repair and replacement of this part have their own nuances, which can not be neglected, otherwise you can even further damage the equipment. But do not worry ahead of time. If the sud error lights up on the display, the probability of a breakdown of the control module is very low.

Thus, in most cases, the causes that generated the sud error can be eliminated on their own. The main thing is to be patient and act according to your plan. Good luck
