SUD error in Samsung washing machine

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

Error value

Those who speak English well can easily understand what the SUD error is telling the user. These three letters are taken from the word SUDS, which means soap suds. It is not difficult to guess that this code did not appear by chance, but because too much foam had formed in the car. In more detail, this error means that the washing machine has entered the mode to eliminate 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 the Sud error, but this does not mean that nothing happens with increased foaming. It’s just that different models of washing machines have different codes for the same error. An analogue of this error are codes 5d and Sd, they are the same thing because the number 5 and the letter s are not distinguishable on a small display of the equipment.

Note that even without knowing the exact decoding of the code, you can understand the reason for the machine stopping if you carefully look at the drum. You can't help but notice the large amount of foam.

Reasons for appearance

On Samsung washing machines, the sud error can be caused by various reasons. The main one is related to powder. The reason is this:

• use of powder not intended for automatic machines.The fact is that special powders automatically add antifoam agents, but powders for hand washing do not contain them, so they cannot be poured into the washing machine;
• low quality fake powder;
• the dosage of powder has been exceeded. If things are bulky, it is better to reduce the amount of detergent or use a special powder. And if the powder is concentrated, then it generally needs to be poured strictly according to the dosage.

If the powder you use is beyond doubt, then the problem is that the washing machine is faulty. Such malfunctions include:

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

What to do yourself, and what to turn to a specialist?

You can eliminate most of the reasons that caused the Sud error to appear on your own. 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 still appears on the display, then do the following:

• press the off button, then turn off the power to the machine;
• open the drum and remove the laundry;
• the door may be blocked, then drain the water from the tank through the emergency drain at the bottom of the machine or through the filter;
  

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

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

If, when performing this mode, the message sud appears again, then with a high probability we can talk about a breakdown of the foam sensor.It is not available in all washing models, and in some machines its function is performed by a water level sensor, which is often called a pressure switch. The foam sensor cannot be repaired and must be replaced. With this problem, you should contact a specialist who will find the necessary similar part and install it correctly.

If the pressure switch breaks down, you can do the repairs yourself. This part can be changed quite easily, you need:

1. disconnect equipment from communications;
2. remove the top housing cover;
3. Find the water level sensor in the upper corner of the washing machine;
4. remove the air duct;
5. disconnect flash drives with wires;
6. connect a new part;
7. assemble the machine.

In some cases, the system may display a Sud error if the foam does not leave the drum due to a partial blockage in the hose or drain pipe. These parts need to be cleaned. The drain hose is disconnected from the machine and cleaning is carried out using a cleaning cable. To rinse the pipe, you need to remove it from the machine. This can be done through the bottom of the washing machine, you need

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

You may need new clamps after cleaning the pipe; they are usually replaced.

As for the “brain” of the machine, or rather the electronic board, we always recommend contacting a specialist with this problem. Both repair and replacement of this part have their own nuances, which cannot be neglected, otherwise you can damage the equipment even more. But don't worry ahead of time. If the sud error appears on the display, the likelihood of a control module failure is very low.

Thus, in most cases, you can eliminate the reasons that gave rise to the sud error yourself.The main thing is to be patient and act according to the plan. Good luck!
