3C
Samsung Dishwasher Error 3C: Pump Operation Error — Wash Pump Failed

The incoming water supply to the dishwasher exceeds the safe operating temperature limit (above 176°F / 80°C). Samsung dishwashers heat their own water and are designed for a cold or warm supply — not a supply that is already at high temperature.

Are all Samsung dishwasher codes the same across models?
Not always. Meanings can vary by series or model, so the guidance here stays conservative and recommends checking the manual for model-specific wording.
