What Does the TROUBLESHOOT Code Mean?

Samsung dishwashers share common failure patterns across models. The most important Samsung-specific knowledge: LC is frequently a condensation false positive, SC/5C/SE drain codes are almost always cleared by cleaning the pump mesh (not just the filter), and control lock (CL) disables all buttons including Power.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

LC error from condensation in base pan40%

Drain blockage in filter or pump mesh (SC/5C/SE)24%

No water supply due to closed valve or clogged inlet screens (4C)14%

Door latch not signaling closed12%

Control lock preventing operation10%

Frequently Asked Questions

What is the first thing to check when a Samsung dishwasher has a problem?

Check the display for an error code. The two-character code tells you exactly which subsystem has failed and points you to the right repair. If no code is showing, start with the breaker and control lock.

How do I run Samsung dishwasher diagnostics?

Hold Sanitize and Hi-Temp simultaneously for 5 seconds. The display will enter diagnostic mode and scroll through any stored fault codes.

What maintenance prevents most Samsung dishwasher problems?

Clean the filter basket monthly and the pump mesh with a small brush every 2-3 months. These two maintenance steps prevent most SC/5C drain codes. For LC prevention, run Normal cycles instead of Sanitize for daily loads.
