Samsung washing machines Error Codes

Samsung uses information codes to point to the stage or system that needs checking. The same family can appear with older and newer code formats, so the aliases below are grouped only where Samsung groups them in its own support table.

Before you use this table: Code sets vary by model. If your machine shows a code not listed here, use the model manual or Samsung support page for that exact appliance.

Leading zeros, dashes and spacing do not matter: E01, E-1 and E1 find the same row.

Manufacturer-documented Meaning taken from a manufacturer manual or support page.   Reported Consistent owner and technician reports; the manufacturer has not published this code. Confirm with them if it matters.
