Samsung Dishwasher 9C1 Error Code

On a Samsung dishwasher, 9C1 (also shown as UC or 9E1) means the control has detected an abnormal or excessive voltage condition and gone into protection mode. It often shows up after a power flicker, a surge or a breaker trip. The dishwasher powers on but refuses to wash, even though there is no water or mechanical problem.

Check the power supply

The manual starts with the incoming AC supply: the wall outlet or circuit, the power cord and the line connection.

Restart after a surge or flicker

If a surge, flicker or breaker trip came just before 9C1 first appeared, switch the dishwasher off at the wall or breaker and wait at least 1 minute. Power it back up and start a normal wash right away. If the code clears and the dishwasher runs, it was a temporary line disturbance and the control recovered. If the code is still there, go on to the next step.

Try a dedicated circuit

Plug the dishwasher into a good, dedicated outlet or circuit. No extension leads, no multi-adapters, and nothing heavy such as a heater or tumble dryer on the same outlet. If the code disappears on a clean circuit, the trouble was the original supply and not the dishwasher.
