Samsung Dishwasher Error Code dE

The dE code means the dishwasher's Auto Door Open system tried to unlatch and open the door at the end of a cycle but the door opening was not detected by the sensor. The control board retried the command three times before displaying the fault. This feature is used to release steam and aid drying, so when it fails, the code is triggered to alert you that the mechanism needs attention.

The dE code relates to the automatic door-open drying feature, not to water heating or pump operation, so the dishwasher may still complete wash cycles. However, running it repeatedly while ignoring the fault can strain the actuator system and may affect drying performance. It is best to diagnose and resolve the issue before continued use.

Repair costs vary depending on the faulty component. Replacing the Auto Door Open actuator typically runs between $80 and $200 in parts and labor, while a door position sensor or latch repair may fall in the $60 to $150 range. If the control board is at fault, costs can be higher, generally between $150 and $350 or more depending on the model and labor rates in your area.

Some causes of the dE error are DIY-friendly, such as clearing an obstruction around the door latch or reseating a loose wiring connector. Replacing the actuator or door position sensor requires basic appliance repair skills and access to the correct replacement part. If you are not comfortable working with the internal components of a dishwasher, a technician should perform the repair.

A power reset may temporarily clear the dE code from the display, but if the underlying mechanical or electrical fault remains, the code will return the next time the Auto Door Open system activates at the end of a cycle. A reset is useful for confirming whether the fault is intermittent, but it does not repair the actuator, sensor, or latch.
