Understanding Samsung Dryer Error Codes, Complete Fix Guide

Most Samsung dryers don’t have a full diagnostic mode, but you can check for error codes by watching the display when something goes wrong. If your dryer has a smart panel, it may flash specific codes or lights. You can also unplug it, wait a minute, plug it back in, and see if the error reappears. If you’re unsure, check the manual or call a technician for help.

Blinking lights usually mean the dryer has detected a problem. It could be something simple, like the door not closing properly, or something more technical, like a vent issue or motor error. The lights are your dryer’s way of saying, “Hey, something’s wrong—check me out.

One of the most common issues is the door not latching properly, which causes the DC error. Other frequent problems include blocked vents, faulty sensors, or heating element issues. Thankfully, many of these can be fixed quickly if caught early.

The HE code usually means there’s a heating issue. To reset it, unplug the dryer from the wall or turn off the circuit breaker. Wait about 1–2 minutes, then plug it back in and try again. If the code comes back, it might be time to call a repair tech to check the heating system.

The symbols show things like cycle status (drying, cooling, wrinkle prevent), settings (low heat, timed dry), and alerts (child lock, clean filter, vent check). If you’re not sure what a symbol means, look for the key in your user manual—it explains them all.
