Sud or Sd is displayed:

There are too many suds in the washing machine. The washer will not be able to spin out water with the excess suds. When "Sud" or "Sd" is displayed, the washer automatically extends the rinse time to remove the excess suds. During this time, the washer pauses the tumbling and adds water for additional rinsing. This pause allows the bubbles in the suds to break. This pause and rinsing are necessary and may occur several times to eliminate the suds.

Are you using HE or High Efficiency Detergent?

Use only HE or High Efficiency detergent. Always measure detergent. If you have very soft water, you may need to use less detergent. Using non-HE detergent or more than the manufacturer's recommended amount of detergent can cause excessive suds. The excess suds can cause the washer to run at a reduced spin speed, resulting in very wet loads, or error codes to appear.

Did you use "no splash" or "easy pour" liquid chlorine bleach? 

This type of liquid chlorine bleach contains a thickening agent that may create excess suds in washers. If this is the case, run the washer with regular liquid bleach products.

Is the drain hose kinked or clogged?

The Sud or Sd code may be the result of a restricted drain hose or standpipe (drainpipe).

Make sure that the drain hose is not kinked or clogged.
