Samsung Washer code **9C1** is associated with **power / 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. 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 **9C1**. Search normalization stores it as **9C1** while preserving the characters a homeowner actually sees.

Quick answer
Power / voltage error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 9C1 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 **9C1** is associated with **power / 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. 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 **9C1**.

Signs
Symptoms you may notice
A symptom that fits 9C1 is that the appliance may stop, restart, or refuse a high-load function.
When the 9C1 condition is present, the code can appear after a surge, brownout, outage, incorrect supply, or frequency problem.
When the 9C1 condition is present, some models preserve the display even when one required power leg or voltage range is abnormal.
The 9C1 display becomes more meaningful if 9C1 appears during the washer stage associated with power / voltage error.
One clue that supports the 9C1 diagnosis is that the cycle can 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.
Before requesting service for 9C1, confirm the breaker has not tripped and the appliance is connected as specified by Samsung.
A safe owner-level check is to if the event followed an outage or surge, perform only the documented one-time power reset.
A safe owner-level check is to do not perform live mains-voltage measurements unless qualified.
The next non-invasive check is to stop if breakers trip repeatedly, plugs/outlets overheat, or there is arcing.
To rule out an accessible cause, record the code and the cycle stage where it appears.
To rule out an accessible cause, check owner-accessible water supply, drain hose/filter, load balance, door, detergent, or power only when relevant.
Important safety warning. When working around a washing machine that shows 9C1, keep the checks external and non-invasive. 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 9C1, 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.
You can try the one reset Samsung documents for the model, but **9C1** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
Do not keep operating the appliance through a hazardous symptom just to see whether **9C1** 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 **9C1** 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 9C1** separate from same-looking codes used by other Samsung appliance families.
