What your Samsung dishwasher is telling you
Applies to Samsung dishwashers with a digital display; models without a display use flashing lights instead. 1E/IE means different things on Waterwall models (clogged filter) and Rotary-arm models (high temperature heater error).
That code isn’t on this list. It may be specific to your model, so call or text me at (480) 292-4746 with the code and model number.
1E
Waterwall models: water isn’t getting through the filter. Rotary models: the temperature inside the dishwasher is too hot.
Also shown as IE
Try this first: Waterwall models: clean the fine filter at the bottom of the dishwasher. Rotary models: switch the dishwasher off at the circuit breaker for 30 seconds and back on, empty it, fill the detergent dispenser and run a Normal cycle.
Meaning depends on whether the model is a Waterwall or Rotary model.
3C
Pump operation error: the pump has failed.
Try this first: Turn the dishwasher off and try starting the cycle again. If the code keeps coming back, call me.
3E
High temperature water supply error: the incoming water is too hot.
Try this first: Make sure the hot water supply is not set above 176°F.
4C
Water supply error: the dishwasher isn’t getting water at the pressure or temperature it needs.
Also shown as 4E

Try this first: Empty the dishwasher, add detergent and run a Normal cycle. If it happens again, switch the dishwasher off at the breaker and call me.

tE
Temperature sensor error: the temperature inside the dishwasher is being detected incorrectly.
Try this first: Empty the dishwasher, add detergent and run a Normal cycle. If it happens again, switch the dishwasher off at the breaker and call me.
When to call me
If the safe check doesn’t clear the code, or the same code keeps coming back, the dishwasher needs a real diagnosis. Error codes point to the system that failed, not always the exact part, so I test before I replace anything.
Never open panels, bypass a safety switch or work on gas or wiring yourself. Unplug the appliance or turn off its breaker if you smell burning or see water near electrical parts.

Where These Codes Come From
I checked every code on this page against Samsung’s own documentation on October 18, 2026, and left out any code I couldn’t confirm there. Meanings can differ between models and model years, so your owner’s manual or the tech sheet inside your dishwasher has the final word for your exact model.
