Samsung dishwasher LC error code
What LC means on a Samsung dishwasher
Leak detected: water in the base.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
When your Samsung dishwasher shows LC, it is telling you it has detected a leak, with water collecting in the base of the machine. You may notice it alongside beeping or flashing lights, water leaking out or sitting in the base, or the dishwasher tripping the electrics.
Engineers sometimes find that water is seeping from the drain pump, the part that pumps dirty water out of the dishwasher. A leak like this does not always show while the machine is running normally, so it can take a closer look to find where the water is coming from.
An engineer will usually run the dishwasher to watch for leaks, then examine the machine more closely to trace the source of the water in the base. Where the drain pump is at fault, they replace it and run the dishwasher again to check it works properly. A new pump may need to be ordered and fitted at a second visit.

Before you check anything yourself
- Switch the dishwasher off and unplug it, or turn it off at the isolator switch, before you touch anything. Our guide to safely isolating an appliance walks you through it.
- An error code tells you where to look, not that it's safe to take the dishwasher apart. Don't remove panels or covers to get at the parts it points to: that's an engineer's job.
- If it involves the mains supply, sealed parts, or you're not confident at any point, stop and book a qualified engineer rather than risk injury or further damage.
