The **3C** display on a Samsung dishwasher points to **circulation / wash-motor error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **3C**. Search normalization stores it as **3C** while preserving the characters a homeowner actually sees.

Quick answer
Circulation / wash-motor error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 3C 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 **3C** display on a Samsung dishwasher points to **circulation / wash-motor error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **3C**.

Signs
Symptoms you may notice
When the 3C condition is present, the affected drum, wheel, brush, auger, pump drive, or mechanism can not move as expected.
One clue that supports the 3C diagnosis is that the appliance may hum, jerk, stop, or retry the motion.
Depending on the exact model, the code can appear when the control fails to receive expected speed or position feedback.
On affected Samsung dishwasher models, 3C appears during the dishwasher function associated with circulation / wash-motor error.
When the 3C condition is present, the cycle may stop, drain, fail to fill/heat, or repeat a stage.
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
A safe owner-level check is to remove only user-accessible obstructions from the affected moving part.
To rule out an accessible cause, do not force a locked drum, brush, wheel, or mechanism.
Before opening any service area, note whether the motor attempts to start and whether unusual noise or burning smell is present.
With 3C recorded, stop use immediately for overheating, smoke, or electrical odor.
A safe owner-level check is to record the code before resetting.
For 3C, start by doing this: 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. If resolving 3C would require energized internal access, that is the point to hand the diagnosis to a qualified technician.

When to request repair service
If the owner-accessible checks do not clear 3C, A repeat motor/drive code can require mechanical-load, winding, sensor, harness, inverter, or control testing. The repair should confirm the monitored function and its feedback before any board or component is condemned.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
One controlled restart is reasonable after correcting an obvious external issue. A recurring **3C** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
Do not keep operating the appliance through a hazardous symptom just to see whether **3C** clears. If there is heat, water, electrical, gas, or food-safety risk, stop and arrange diagnosis.
Not automatically. Samsung error codes are diagnostic indicators, not part numbers. Confirm the circuit around **3C** before replacing anything.
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 3C** separate from same-looking codes used by other Samsung appliance families.
