Error code9C2 Will not wash
ApplianceDishwasher
Quick answer
9C2 on a Samsung dishwasher means it powers on but will not wash or stops mid-cycle, often after power dips, brownouts or extension-lead use.
Model compatibility: Samsung reuses codes across series and model years, so 9C2 Will not wash 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
The unit powers on but will not wash or stops mid-cycle, often after power dips, brownouts or extension-lead use.
A Samsung dishwasher with 9C2 on the display will not start, or stops partway through a cycle. The panel comes on, but the dishwasher will not wash. Samsung notes that it often follows power trouble such as dimming lights, brownouts, breaker trips or running on an extension lead.
Reset by unplugging
Unplug the dishwasher for 5 minutes, then turn it back on. If the problem persists, repeat the same step after another 5 minutes.
Test another outlet
Move the dishwasher to a proper, dedicated outlet or circuit, or test it on one. Keep extension cords and multi-plug adapters out of it, and do not let heavy appliances share that outlet. When 9C2 goes away on a correct circuit, the external supply was the cause, not the dishwasher.
For help in Los Angeles with a Samsung dishwasher that keeps showing 9C2, phone (310) 896-4231. Have the code, the model number and a list of the outlets you tried. Our dishwasher repair page has details.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
