bE4
Samsung Dryer
Severity: ModerateWhat Does This Error Mean?
The bE4 error means the Samsung dryer's control board has detected a button that is stuck or continuously sending a signal. The dryer will not start any cycle while a button fault is active. This is usually a stuck physical button or a failing keypad.
Affected Models
- DVE45R6100W
- DVE50R8500V
- DV45H7000EW
- DV50K8600EV
- Most Samsung electric and gas dryers
Common Causes
- A button physically stuck in the pressed position from residue or moisture underneath
- Moisture behind the control panel causing a keypad contact to short circuit
- Worn or cracked membrane keypad with a failing button contact
- Child Lock activated and another button fault occurring simultaneously
- Control board sending incorrect signals due to a firmware or hardware fault
How to Fix It
-
Press and release each button on the control panel one at a time.
Work through every button firmly. A lightly stuck button is sometimes freed just by pressing it a few times.
-
Wipe the control panel with a dry cloth.
Remove any lint or detergent residue from around the buttons. Avoid spraying cleaning products directly onto the panel.
-
Disable Child Lock if it is active.
Press and hold the Child Lock button for 3 seconds to turn it off. The indicator light will turn off when it is deactivated.
-
Unplug the dryer for 5 minutes, then plug back in.
A hard reset clears temporary control board faults. This resolves bE4 in cases where the fault was caused by a power issue.
-
If bE4 returns immediately, the keypad membrane or control board needs professional replacement.
Contact Samsung support at 1-800-726-7864 or schedule a local appliance technician.
When to Call a Professional
If pressing, cleaning, and resetting the control panel does not clear bE4, the keypad or control board requires professional replacement. These parts are inside the dryer top panel. Expect repair costs of $100–$300 depending on the specific part needed.
Frequently Asked Questions
What is the difference between bE, bE1, bE2, bE3, and bE4 on Samsung dryers?
All bE codes indicate a stuck or faulty control panel button. The number after 'bE' identifies which button or button group is affected. bE4 specifically indicates a fault in the fourth button zone or a persistent shorted key condition. The troubleshooting approach is the same for all bE codes.
Can lint cause a bE4 error on a Samsung dryer?
Indirectly, yes. Lint can work its way into the gaps around control panel buttons over time. This can cause buttons to stick slightly and trigger bE errors. Regularly wiping the control panel with a dry cloth helps prevent this.
How do I know if the bE4 error is the keypad or the control board?
A technician can determine this with a multimeter. Generally, if only one specific button triggers the error, the keypad is more likely faulty. If the error occurs randomly without any button stuck, the control board is the more likely suspect.
