A helpful feature of Samsung washing machines is an automatic diagnostic process that displays an error code on the control panel when the machine experiences a problem with one of its parts. For instance, when the door isn't fully engaged, the tub is too full or something is caught in the door, you may see a de, de1 or Ed code on the control panel display based on the model that you have.

You can also run special diagnostic tests by pressing multiple keys at the same time. These tests check the following:

  • LED operation and functionality
  • software and model versions
  • operating modes of water valve, door, motor, drain pump and more
  • and electrically erasable programmable read-only memory check.

Quick Test

To run a diagnostics test on the door, motor, drain pump, water valve and various functions of the machine, press the Soil_, _Spin and Power buttons at the same time. This generates a quick test to check functionality. If there's a problem, the machine will display an error code.

Clear Memory

To enter the EEPROM clear check process, press the Delay Start and Power buttons at the same time. This step clears the memory and resets the machine after it has an error code. When the EEPROM process has completed successfully, the display reads Goo for "good," or FAI for fail.

Error Code List

The following error codes, updated in March 2014 by Samsung, include the new and old error codes that display on many Samsung washers:

If your Samsung machine displays a code that is not on this list, it may be an older model. Locate the model number for your machine either on the inside door of front loaders or the top of the control panel at the back for top loaders. Once you know the model number, Samsung's support site provides user manuals for your model that includes its error codes.
