If you see a Samsung washer SUD error code during a washing cycle, it implies the suds have risen above the normal amount in the drum. This message specifically indicates that the washing machine is lowering foaming. It just came to a halt for 5-10 minutes to let the suds evaporate and the washing cycle resume.
Where does the SUD error come from?
Foaming control is available on Samsung washers. If there are too many suds, the machine shifts to a setting that reduces them. The SUD error means that the washer is unable to eliminate suds and that the foam must be allowed to disperse naturally. It depends on the concentration of washing powder in the water and can last for a long period.
All three codes – 5D, SUD, and SD – are nearly identical. Some Samsung washing machines display the SUD error. The fault codes for the other Samsung washers are different. Because the number 5 and the letter s are difficult to distinguish on a small display, the 5d and Sd error codes are equal to the SUD one.
If you’re certain it’s not the powder, your washing machine is broken. Namely:
- The foam level sensor has stopped working.
- The pressure switch is malfunctioning.
- The drain system’s elements (hose, branch pipe, and sewer) are partially obstructed.
- The control board has failed, which is a very uncommon occurrence.
The cause of the error code SUD
If the display displays the SUD error, you must first establish the source of the issue. If the following conditions are met, the error will appear:
- You used a washing powder that wasn’t designed for automated washers.
- You’ve used some low-quality powder.
- You have used more detergent than is required for one washing cycle.
- The foam level sensor has stopped working.
- The pressure switch has failed.
- The sewer, branch pipe, or release hose is obstructed.
- The control board has suffered a significant failure (but this reason is very rare).
First and first, think about your washing powder. You can solve the issue by making a change.
How do I fix the problem?
If the SUD code appears on your Samsung washing machine and suds are plentiful in the drum, try the following steps:
- Allow a few moments for the suds to disperse. After that, the cycle will continue on its own. If your Samsung washer requires it, press the start button.
- After the wash cycle is over, clean the drain filter.
- Remove any extra powder by running the washing machine without any garments in it and using a long wash cycle with a high temperature;
- If you see a lot of suds, it’s time to switch detergents.
If the code is present but there are no suds in the drum:
- Turn the machine off.
- Remove the garments and drain the water into the emergency drain rather than attempting to open the closed door.
- The drain filter should be cleaned.
- To test the machine, start it using the previously selected cycle.
Clean the powder residue from the drain and the drum completely.
If the SUD code appears again during the cycle, the foam level sensor is most likely broken. Foam sensor, which isn’t accessible in all Samsung washing machine models. Instead, the water level sensor, often known as the pressure switch, performs this function. The foam level sensor is damaged beyond repair and must be replaced.
This component is simple to replace:
- Unplug the washer and turn off the water.
- Remove the lid from the top.
- The water level sensor is located in the machine’s upper corner.
- The air duct must be removed.
- The wires should be disconnected.
- Install a new component
- Invert the order of the elements and reinstall them.
If the suds haven’t gone away due to partial obstruction in the hose or branch pipe, the system may display the SUD code. You must clean these components. Clean the drain hose by disconnecting it from the machine and cleaning it with a wire, for example. Remove the branch pipe from the washer to clean it. You can get to it by going to the machine’s bottom:
- Turn the washer over to the side.
- If there is a bottom, carefully remove it.
- Unscrew the pipe clamps that connect the branch pipe to the tub and pump.
- Reinstall the element after cleaning it.
When should I contact a repairer?
If you require assistance from a professional, you should:
- Even if there are no suds in the drum, you’re still getting the SUD error code. The malfunction of the foam level sensor could be the cause. The sensor should then be replaced.
- The SUD issue appears when the Samsung washing machine is turned on or during a cycle, which ends when the code appears. The water level sensor has failed. It should be replaced.
- The washer drains the water for a long time without detergent; when you add the powder, the mistake occurs. The cause is material obstructing the drain hose or sewer branch pipe. It is required to clean them in order to remove the error.
- When you start the washing machine or during the wash or rinse cycles, the SUD error occurs. It can sometimes suggest a problem with the control unit. The most common outcome is a unit replacement.
You can try to remove the code again after the suds have dissipated. Simply press the “Start” button on the Samsung washing machine to restart it. If none of the above suggestions have worked to fix your washing machine, call a repairman.
