What PC Means
PC is the Zone Wash error on Samsung’s US dishwasher article: the mechanism that directs water to one rack only is not operating as expected. Samsung’s step is to turn the dishwasher off and try to start the cycle again. On a Samsung washer PC means the clutch position, an unrelated part.
Common Causes of PC
- Zone Wash diverter valve or motor not reaching position
- Diverter position sensor problem
🔧 One Safe Check You Can Try
Turn the dishwasher off, wait a moment and start again, choosing a cycle without the Zone Wash option. If the dishwasher then completes normally, the zone diverter is the problem and the machine can be used without that option until it is repaired. If PC returns regardless of the option, Samsung directs owners to service.
⚠ Why You Shouldn't Go Further Than That
- The diverter is in the sump under the tub, reached with the dishwasher out and the base open.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
