The **PC** display on a Samsung dishwasher points to **zone wash / clutch-position detection error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. A display code is evidence from the control system, not a component test result. That distinction matters because a connector, supply condition, obstruction, or feedback signal can mimic a failed component. The recorded display form is **PC**. Search normalization stores it as **PC** while preserving the characters a homeowner actually sees.

Quick answer
Zone Wash / clutch-position detection error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so PC may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The **PC** display on a Samsung dishwasher points to **zone wash / clutch-position detection error**.

Signs
Symptoms you may notice
On affected Samsung dishwasher models, the affected drum, wheel, brush, auger, pump drive, or mechanism can not move as expected.
The PC display becomes more meaningful if the appliance may hum, jerk, stop, or retry the motion.
On affected Samsung dishwasher models, the code can appear when the control fails to receive expected speed or position feedback.
PC can be accompanied by this pattern: pC appears during the dishwasher function associated with zone wash / clutch-position detection error.
On affected Samsung dishwasher models, the cycle can stop, drain, fail to fill/heat, or repeat a stage.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
With PC recorded, remove only user-accessible obstructions from the affected moving part.
The next non-invasive check is to do not force a locked drum, brush, wheel, or mechanism.
With PC recorded, note whether the motor attempts to start and whether unusual noise or burning smell is present.
For PC, start by doing this: stop use immediately for overheating, smoke, or electrical odor.
With PC recorded, record the code before resetting.
Before opening any service area, verify water supply, drain path/filter, door, detergent/suds, and visible leaks only when relevant.
Important safety warning. Stop use for active leakage near electrical parts, burning smell, or repeated breaker trips. Do not defeat leak or door-safety switches. For PC, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.
Get help
When to request repair service
A repeat motor/drive code can require mechanical-load, winding, sensor, harness, inverter, or control testing. In a service visit for PC, model-specific testing should follow the zone wash / clutch-position detection error circuit rather than treating the code as proof of one failed part.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
A single documented power reset can help after an external condition or power event is corrected. If **PC** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **PC** should not be ignored if performance is deteriorating or the display keeps returning.
No. **PC** tells you which condition or check the control detected. The same display can result from the named component, its wiring, a connector, a supply/airflow/water condition, or the control that reads it.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Dishwasher PC** separate from same-looking codes used by other Samsung appliance families.
