Samsung Dishwasher PC / PE Error Code
Zone Wash or Half Load error. Here is what it means and how to clear it, easiest fix first.
A wash option that sends water only to part of the dishwasher isn't working. Samsung links PC to Zone Wash and PE to Half Load; both rely on a valve that splits water between areas.
US/Canada: PC = Zone Wash, PE = Half Load. Australia lists PC / PE together as a dividing valve fault. UK lists them together for cycles that won't start with Zone Wash or Half Load selected.
How to fix Samsung PC / PE
Power cycle the dishwasher
Switch the dishwasher off at its circuit breaker (or unplug it) and wait about 30 seconds. Restore power and start a fresh cycle. If the code clears and stays away, it was likely a one-time glitch.
Run a cycle without the option
Deselect Zone Wash or Half Load and run a Normal cycle with a regular load. If that works, try the option again with an empty tub and detergent.
When to call a technician
If the error keeps returning, request service. The dividing valve may need replacing.
