Possible Causes

How to Fix / Troubleshooting
Safety first: Do not operate the washer-dryer combo on a damaged outlet or cord. Risk of fire or shock.
Steps to address:
- Check power source: Ensure the unit is plugged directly into a properly grounded wall outlet. Do not use extension cords or multi-plug adapters.
- Inspect power cord: Look for cuts, burns, or loose prongs on the Samsung power cord. Replace if damaged.
- Monitor household voltage: If lights flicker or other appliances behave erratically, have an electrician check your home's electrical system.
- Reset unit: Unplug for 5 minutes, then reconnect and run a short cycle to see if UC reappears.
When to stop: If UC persists with a stable power supply, the internal power supply on the PCB may be faulty and requires professional replacement.
