Samsung Dishwasher Error Code bC2

The bC2 code means the dishwasher has detected a button or key that has been held in the pressed position for 30 continuous seconds or longer. The control board registers this as an input error. The machine will continue its current wash cycle while the error is active, but the underlying cause needs to be addressed to prevent the fault from recurring.

A power reset can temporarily clear the bC2 code, but if the root cause is still present, such as moisture on the panel or a failed touch sensor, the error will return. To reset, turn off the dishwasher at the circuit breaker for several minutes, then restore power. If bC2 reappears after the reset, the underlying hardware issue needs to be resolved.

If the fix is simply cleaning moisture or debris from the touch panel, there is no parts cost. If the touch key panel assembly needs replacement, parts alone typically range from $50 to $150 depending on the model, with professional labor adding another $80 to $200. A wiring harness repair or control board diagnosis may fall in a similar labor range, so getting a diagnostic estimate before authorizing repairs is worthwhile.

Start by inspecting the touch control panel for water, moisture, or any foreign substance such as food residue or grease. Dry or clean the panel surface and check if the error clears. If the panel is clean and dry but the error persists, press each button to check for one that feels physically stuck. A faulty touch panel assembly or wiring harness may require professional diagnosis and part replacement.

Because the dishwasher continues its cycle during a bC2 error, using it is generally not an immediate safety risk. However, a persistent input fault can interfere with normal control operation over time and may indicate moisture intrusion or panel damage that should be addressed promptly. It is best to diagnose and resolve the cause before relying on the appliance for regular use.
