What the bC error code actually means

Your Samsung dishwasher is showing the bC code because it thinks one of the control panel buttons has been held down for too long, or the panel is not communicating properly with the main control board. This can happen if something is sitting on the control panel, moisture has gotten under it, or there is a wiring or board problem. Clearing the panel surface and checking for obstructions is the best first step.

Questions people ask about bC

What does bC mean on a Samsung dishwasher?
The bC code means the dishwasher detected a touch button being held continuously for 30 seconds or more, or there is a communication failure between the Sub PBA and the touch button PBA. The dishwasher locks out the cycle until the condition is resolved. This can be caused by a physical obstruction on the panel, a wiring issue, or a failed control board.
How do I fix the bC error on my Samsung dishwasher?
Start by checking the control panel for any object pressing against it and wipe the surface clean of any residue. Next, inspect the connector and ribbon cable between the Sub PBA and the touch button PBA for looseness or damage, and reseat any loose connections. If the code persists after those steps, one of the two boards likely needs replacement.
How much does it cost to repair a Samsung dishwasher bC error?
If the fix is simply clearing an obstruction or reseating a connector, there may be no parts cost at all. If the touch button PBA needs replacement, parts typically range from $30 to $80 depending on the model, plus labor if a technician is hired. A Sub PBA replacement generally costs more, with parts in the range of $60 to $150, and professional repair labor adds to that total.
Will resetting my Samsung dishwasher clear the bC error code?
A power reset by unplugging the unit or shutting off the circuit breaker for a few minutes may temporarily clear the bC code if the cause was a momentary glitch. However, if a physical obstruction is still on the panel or a wiring connection is faulty, the code will return. Addressing the root cause is necessary for a permanent fix.
Is it safe to use my Samsung dishwasher when the bC code is showing?
The bC error typically prevents normal operation, so the dishwasher will not run a cycle while the fault is active. There is no immediate safety hazard from the error itself, but you should not attempt to force operation or bypass the error. Resolve the underlying cause before running the appliance.
