Samsung Washer code **9C** is associated with **power-supply / voltage error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. 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 **9C**. Search normalization stores it as **9C** while preserving the characters a homeowner actually sees.

Quick answer
Power-supply / voltage error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 9C 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
Samsung Washer code **9C** is associated with **power-supply / voltage error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. A display code is evidence from the control system, not a component test result.

Signs
Symptoms you may notice
While 9C is active, the appliance can stop, restart, or refuse a high-load function.
The 9C display becomes more meaningful if the code can appear after a surge, brownout, outage, incorrect supply, or frequency problem.
On affected Samsung washing machine models, some models preserve the display even when one required power leg or voltage range is abnormal.
While 9C is active, 9C appears during the washer stage associated with power-supply / voltage error.
While 9C is active, the cycle may pause, stop, retry, drain, or refuse to advance until the condition is cleared.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
As an external check for 9C, confirm the breaker has not tripped and the appliance is connected as specified by Samsung.
The next non-invasive check is to if the event followed an outage or surge, perform only the documented one-time power reset.
With 9C recorded, do not perform live mains-voltage measurements unless qualified.
As an external check for 9C, stop if breakers trip repeatedly, plugs/outlets overheat, or there is arcing.
As an external check for 9C, record the code and the cycle stage where it appears.
Before opening any service area, verify owner-accessible water supply, drain hose/filter, load balance, door, detergent, or power only when relevant.
Important safety warning. Safety takes priority over clearing 9C. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips.

When to request repair service
If the owner-accessible checks do not clear 9C, Persistent power/voltage codes need the household supply and appliance power/control circuits checked safely before parts are replaced. 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 **9C** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **9C** should not be ignored if performance is deteriorating or the display keeps returning.
Not automatically. Samsung error codes are diagnostic indicators, not part numbers. Confirm the circuit around **9C** 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 **Washer 9C** separate from same-looking codes used by other Samsung appliance families.
