Samsung Dishwasher Error Code 8C

The 8C code indicates that the dishwasher has detected an abnormal voltage condition on its internal DC link circuit, meaning the voltage was either too high or too low. To protect its electronics, the appliance switches itself to stop mode and will not operate until the issue is resolved. The most common cause is unstable or out-of-range voltage from the home's electrical supply.

A reset by cutting power at the circuit breaker for several minutes may clear the error if it was caused by a temporary event such as a power surge or brief blackout. However, if the underlying voltage problem is still present, the code will return as soon as the dishwasher attempts to operate. Resetting is a good first step but is not a permanent fix if the supply voltage or an internal component is faulty.

If the cause is a supply-side electrical issue, costs may be limited to an electrician's service call, typically in the range of $75 to $200 depending on your area and what work is needed. If a power control board or inverter drive component needs replacement, repair costs including parts and labor can range from $150 to $400 or more. Getting a diagnosis before committing to parts replacement is advisable since supply voltage issues are often the actual cause.

Start by checking your home's electrical supply voltage at the outlet or junction where the dishwasher connects. If the voltage is stable and correct, try resetting the dishwasher by cutting power at the breaker for a few minutes. If the error returns consistently, inspect the power control board or contact a qualified technician to evaluate the internal drive circuitry.

The dishwasher's stop mode is a protective response, so the appliance will not run while the 8C fault is active. You should not attempt to bypass this protection, as operating under abnormal voltage conditions could cause further damage to the control electronics or motor. Address the voltage issue before returning the unit to regular use.
