Quick Fix:

FAQ

To reset your Samsung dishwasher, turn off the power at the circuit breaker for 1–2 minutes, then turn it back on. This can clear minor errors. If the error code returns, it may indicate a deeper issue that needs repair.

Most Samsung dishwashers use similar error codes, but there may be slight differences depending on the model. Always check your user manual for the most accurate interpretation, or contact a repair technician for help.

If the error persists after basic troubleshooting—like checking filters, hoses, and water supply—it’s best to call a certified technician. Error codes related to leaks, drainage, or heating often require professional repair.
