Frequently Asked Questions

How do I reset a Samsung dishwasher error code?
Hold Start/Cancel for 3 seconds to cancel the cycle and clear the code. If the code persists, turn off the breaker for 30 seconds. Note that LC codes will not clear until the base pan is drained by tilting the unit.
What is the most common Samsung dishwasher error code?
LC is by far the most common, accounting for the majority of Samsung dishwasher error searches. It is frequently a false positive caused by condensation dripping into the base pan during hot cycles, not an actual leak.
How do I enter Samsung dishwasher diagnostic mode?
Press and hold Sanitize and Hi-Temp simultaneously for 5 seconds. The display will scroll through stored fault codes.
Is SC the same as 5C on a Samsung dishwasher?
Yes. SC appears on newer displays and 5C on older firmware. Both codes indicate the same drain fault.
