What to check, in order
- Reset at the wall
Switch off at the socket for 1 minute, then back on.
- Plug straight into the wall
Don't use an extension lead or an adapter. Samsung US says the washer should ideally be on its own circuit.
- Check the plug and socket
Look for scorch marks or a loose fit. If you find either, stop using that socket and call an electrician.
When to call an engineer
If the socket is fine and the code continues, call Samsung service. Call an electrician if other appliances on the same circuit misbehave too.
Quick answers
What does the Samsung UC error code mean?
The washer is getting power that's too high, too low or unsteady. It also shows as 9C1, 9C2, 9E1, 9E2 or 9H1.
Can I fix Samsung UC myself?
Very easy (about 5 minutes). Start with: reset at the wall; plug straight into the wall; check the plug and socket. If the socket is fine and the code continues, call Samsung service. Call an electrician if other appliances on the same circuit misbehave too.
Is Samsung UC worth repairing?
Usually free. It's usually the supply, not the washer. Don't ignore a loose or scorched socket, though.
