What to check first
Stop normal operation while this warning is active. Follow only the documented safe checks or protective-drain instructions for the exact model.
Basic checks
- Keep the dryer out of normal use and check externally that it is on its own circuit without an extension cord.
- Have an electrician check cord installation or voltage concerns; do not access the terminal block or take live measurements.
Applicability
Regional guidance · Samsung dryers covered by the US support page · United States
This scope follows Samsung's US dryer error-code page; display variants and permitted checks can differ by exact dryer model, installation, and market.
Reset or retry steps
- For a stacked multi-control kit that reports 9C1 immediately after the washer is turned on, check the specific Samsung SmartThings update instructions.
- For persistent voltage errors or electrical warning signs, arrange qualified service instead of repeated power resets.
When to call a technician
- Contact an electrician for voltage or power-cord concerns.
- Request Samsung service if the voltage code continues after safe power checks.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
Can I keep using it?
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Disconnect power before any service-access step.
Do not do this
- Do not continue normal cycles while this code is active; any protective-drain sequence must follow the exact model instructions.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Dryer not on its own circuit
- Extension cord use
- Incorrect electric dryer power-cord installation
- Power-grid mismatch after moving a dryer between countries
