Samsung Washer bC Error Code — What It Means
The bC error code on a Samsung washer signals a button or control-panel input fault. Samsung’s code charts break this into bC1 (power button issue), bC2 (control button issue), and bC3 (button defective), but plain bC without a number is model-dependent. Some repair sources treat it as a stuck relay on the display PCB, while certain model families also list bC or bE as a motor issue. Always verify your model’s service literature before ordering parts.
The code typically appears when the control board detects a button continuously pressed or an input circuit stuck closed. On some models the display PCB relay fails to release, which triggers the same fault. Moisture, contamination, or physical damage around the button area can also cause false input signals.
Common Causes
- Stuck or continuously pressed button A button on the control panel is physically binding or held in by the fascia or detergent drawer.
- Failed display PCB relay The relay on the control or display board is electronically stuck and does not release normally.
- Moisture or contamination in the button area Liquid or residue has entered the button contacts and is causing false or continuous input signals.
- Physical damage to the control panel Cracked or worn button membranes or fascia components are misreading inputs.
- Motor circuit issue (model-dependent) On certain model families the bC or bE code is listed as a motor fault, so wiring and motor circuit must be checked.
Step-by-Step Fix
- Power-cycle the washer by switching off at the mains, waiting 30 seconds, then restarting the cycle to clear temporary faults.
- Inspect all buttons on the control panel for sticking, binding, or being held in by the fascia or detergent drawer.
- Clean the button area with the appliance disconnected, using a lightly dampened cloth, and do not flood the panel.
- Remove the top and control fascia to access the display PCB and button contacts if the code returns after cleaning.
- Test the relays and inputs on the display board by pressing each button and listening for normal relay clicks or checking for stuck contacts.
- Replace the display PCB if the relay does not release or the fault persists after mechanical inspection.
- Reassemble and retest with a normal wash cycle to confirm the repair, and check for any remaining error codes.
Parts Often Needed
| Part | Notes |
|---|---|
| Display PCB / control board | Amazon | Replace when the relay is stuck or the board does not respond to button inputs normally. |
| Control panel button assembly | Amazon | Required if buttons are physically damaged, cracked, or the membrane is worn and misreading inputs. |
When to Call a Pro
Call a qualified appliance technician if the code returns after power-cycling and cleaning, if you are not comfortable removing the control fascia and testing PCB relays, or if your model’s documentation classifies bC as a motor issue and you need motor circuit diagnostics. Technicians have the correct service literature and test equipment to isolate relay faults and verify model-specific part numbers before replacement.
