bC
Samsung Washing Machine
Severity: ModerateWhat Does This Error Mean?
The bC error means a button on your Samsung washer's control panel is stuck or continuously pressed. The washer thinks someone is holding a button down. This prevents the machine from operating normally.
Affected Models
- WF45R6100AW
- WF56H9100AG
- WF42H5200AW
- Most Samsung front-load and top-load washers
Common Causes
- A button physically stuck in the pressed position (soap residue or debris underneath)
- Moisture trapped behind the control panel buttons
- Damaged or faulty control board sending incorrect signals
- Child lock accidentally activated alongside a stuck button
- Wiring issue between the control panel and the main board
How to Fix It
-
Press each button on the control panel firmly and release it.
Sometimes a button is just slightly stuck. Press and release every button one at a time to free it.
-
Wipe around all the buttons with a slightly damp cloth.
Dried detergent or residue can cause buttons to stick. Make sure the cloth is barely damp — not soaking wet.
-
Perform a hard reset: unplug the washer for 5 minutes.
This clears temporary control board faults. Plug it back in and see if the error is gone.
-
Check if Child Lock is active.
Child Lock disables the controls and can cause confusion. Hold the Child Lock button for 3 seconds to toggle it off.
-
If the error returns immediately after reset, the control panel may need professional inspection.
A faulty membrane keypad or cracked circuit board will require parts replacement.
When to Call a Professional
If cleaning the buttons and resetting the washer does not clear the bC code, the control panel board may need replacing. This is a job for a technician. Expect costs of $150–$350 depending on the model.
Frequently Asked Questions
Can a power surge cause the bC error on a Samsung washer?
Yes, power surges can confuse the control board. A 5-minute unplug reset often clears surge-related errors. If it happens repeatedly, consider a surge protector for your appliance.
How do I know if my Samsung washer control panel needs replacing?
If the bC error comes back every time you power on the machine, and no buttons are visibly stuck, the control panel board is likely faulty. A technician can confirm this with a diagnostic test.
Does the bC error damage my washer if I ignore it?
The washer will refuse to run while the error is active, so no active damage occurs. However, leaving a stuck button unaddressed can eventually wear out the control board. Fix it sooner rather than later.
