The bE error on a Samsung dryer means a button on the control panel is stuck, shorted, or the machine thinks one is being pressed continuously. Try the reset procedure first — it clears bE without any parts in a large number of cases.
What This Error Means
Samsung’s control board continuously monitors all buttons on the panel. If any button appears to be held down for an extended period, the board throws bE to indicate a button is stuck or the circuit has shorted.
bE (without a number) typically means a temporary stuck-key condition — something physically pressing a button or moisture triggering a false reading.
bE2 is more serious — it means the control board’s internal button matrix circuit has detected a hard failure, not just a stuck key.
Common Causes
- Moisture or condensation on the panel — Steam from laundry or a humid laundry room can get between buttons and trigger false reads.
- Debris under a button — Lint, fabric threads, or small items can lodge under a button and hold it partially pressed.
- Detergent or dryer sheet residue — Sticky residue from dryer sheets can make buttons stick.
- Control panel flex cable failure — The ribbon cable connecting the button panel to the control board can develop an intermittent short.
- Failed control board (bE2) — If bE2 appears, the board’s button detection circuit has failed internally.
Step-by-Step Fix
-
Try a forced reset first. Hold the Start/Pause button for 5 seconds. On some Samsung models, pressing and holding Child Lock for 3–5 seconds will reset the control panel. If the dryer responds and clears bE, you’re done.
-
Unplug for 30 seconds. A full power cycle sometimes clears a temporary button fault.
-
Inspect each button. Press every button on the panel one at a time, firmly, and release. Listen for each one clicking and returning. If one button feels sticky, doesn’t click cleanly, or stays down, that’s your problem.
-
Clean the control panel. With the machine unplugged, lightly dampen a cloth with isopropyl alcohol and clean around each button. Don’t let liquid get inside the panel. Let it dry completely before powering back on.
-
Check the flex cable. On most Samsung dryers, the control panel is accessible by removing 2–3 screws on the back of the top panel and tilting it forward. The ribbon cable connecting the panel PCB to the main board should be seated fully in its connectors at both ends.
-
For bE2 — replace the user interface board. If bE2 appears consistently after a reset, the UI board needs replacement.

When to Call a Technician
bE2 requiring a control board replacement is a straightforward repair if you can identify the correct board part number for your model. If you’re not sure which board to order or not comfortable with panel disassembly, an appliance technician can diagnose and replace it in a single visit.
