Error 5D, SUD, SD – a lot of foam in the Samsung washing machine

If during washing you notice the code 5D, SUD, SD, it means that the foam level in the washing machine has been exceeded. You can see it in the drum or outside the machine on the powder tray.

What does the 5D error say?

Samsung washing machine models are equipped with a foam control function. If there is a lot of it, the machine goes into a mode that contributes to the suppression of foam. The resulting 5D error indicates the impossibility of reducing the amount of foam – the washer is waiting for the foam to settle naturally. Such deposition of foam usually lasts a long time, and depends on the concentration of the powder diluted in water.

All three codes – 5D, SUD, SD – indicate the same malfunction. The designation depends on the machine model.

Why the error occurs

If a SUD error is displayed, you first need to find out the cause of the problem. This code occurs if:

  • For washing, a powder was used that was not suitable for automatic machines;
  • An overly concentrated powder was used, with the foam of which the automatic machine could not cope;
  • Poor quality powder was used;
  • The dose of detergent for one washing cycle has been exceeded;
  • The foam sensor has become unusable;
  • Broken water level sensor;
  • Clogged water drain hose, pipe, sewer;
  • There was a serious malfunction in the operation of the control unit (but the washing machine shows a 5D error for this reason very rarely).

First of all, check the washing powder – often changing it is enough to solve the problem.

What to do to fix the problem yourself

If the Samsung washing machine issues a 5D code during washing, and the amount of foam in the drum is large, then the following actions must be taken:

  1. Wait a little for the foam to settle. Washing will then automatically resume itself. Some models of Samsung washing machines require you to press the wash start button;
  2. At the end of the wash cycle, clean the drain filter;
  3. Remove the remnants of the powder, for which you need to run the washing machine without linen, choosing a long wash mode and a high temperature;
  4. Change the powder to another with the constant appearance of a large amount of foam in the drum.

But what to do when there is no foam in the drum when the code is displayed:

  1. Turn off the machine;
  2. Get linen. With the door locked, drain the water through the emergency drain;
  3. Clean the drain filter;
  4. Run the machine to check the result by selecting the previous mode.

Thoroughly clean the drain and drum of powder residue.

When to call the wizard

You will need to involve a professional in solving the problem if:

  1. The SD error on the scoreboard has not disappeared, and there is no foam in the drum. The cause may be a malfunction of the foam sensor. The sensor needs to be replaced.
  2. Error 5D lights up after starting the Samsung washing machine or during the washing process, which stops after the pop-up code. The reason is a breakdown in the water level sensor. We need to replace it.
  3. The washing machine takes a long time to drain water without powder, and with powder it gives an error. The reason is debris clogged in the drain hose or sewer pipe. To remove the error, you need to clean them.
  4. When starting the washing machine, washing or rinsing, error 5D lights up. Sometimes it indicates a malfunction of the control unit. Most often, the block needs to be replaced.

Resetting errors from the Samsung SM display is sometimes done by simply pressing the “Start” button after the foam has settled from the detergent.

If all the suggested measures did not help to fix the operation of the washing machine, contact the repairman.
