Quick answer
Do not force repeated cycles if clutch-position codes return immediately.
Safety note
Disconnect power before opening panels or touching wiring. If water is leaking near electricity, stop and call a qualified technician.

What PC means
On many Samsung washer models, PC belongs to the sensor reading fault category. A sensor value is outside the range expected by the control board.
Codes and exact steps can vary by model number, production year, and regional design. Use this guide as first-pass orientation and confirm model-specific details with the manufacturer source listed below.
Before you start
Write down the full model number and the exact display text before changing parts or clearing the control. Similar-looking codes can map to different model families, and a reset can erase useful timing clues.
If the appliance shows active leaking, a burning smell, smoke, gas odor, repeated breaker trips, or water near power, stop this checklist and use qualified service.
Common causes
- Temporary sensor reading glitch
- Dirty sensor surface
- Loose sensor wiring
- Failed thermistor, pressure sensor, or humidity sensor
Recommended check order
- Confirm the model number and exact code spelling.
- Disconnect power for 5 minutes to clear a temporary control state.
- Clean accessible sensor surfaces shown in the manual.
- Avoid spraying cleaner into control panels or sensor openings.
- Run a short test cycle after the reset.
- Run one controlled reset only when the appliance is dry, stable, and safe.
- Stop if PC returns immediately or appears on an empty test.
Safe checks before service
- Disconnect power for 5 minutes to clear a temporary control state.
- Clean accessible sensor surfaces shown in the manual.
- Avoid spraying cleaner into control panels or sensor openings.
- Run a short test cycle after the reset.
What not to do
- Do not bypass locks, sensors, fuses, or leak protection to force a cycle.
- Do not open powered panels or touch wiring for a code check.
- Do not assume one display code proves one specific part has failed.
Stop and call a technician when
- The code returns immediately.
- The appliance cannot complete a short empty cycle.
- The suspected sensor is inside a sealed or powered area.
FAQ
Is PC always a broken part?
No. On a Samsung washer, PC usually identifies a sensor reading fault category. A blocked hose, dirty filter, uneven load, or unsafe operating condition can trigger a code before a part failure is confirmed.
Can I reset PC?
A single power reset can be reasonable after visible checks are complete and the appliance is safe. If PC returns immediately, treat it as an active fault rather than a nuisance message.
Why does model number matter?
Brands reuse similar code text across model families. The model number controls the exact manual steps, access points, and service boundary.
