Seeing 1E (sometimes displayed as IE) on a Samsung dishwasher points to a filter or heating circuit failure detected by the control board during the wash. Samsung’s DW80 line groups this problem with sensor and supply-line issues around the sump filter housing.
What can set off 1E
- Food debris or a broken chip of dishware clogging the fine mesh filter above the sump
- A heating element or its thermistor that is not reporting temperature correctly to the board
- A wiring connector near the sump that has loosened or corroded
- Mineral buildup on the filter assembly restricting flow enough to trip a problem reading
What to inspect first
- Twist and lift out the coarse and fine filter assembly at the bottom of the tub and rinse both under running water
- Look closely for cracked plastic tabs, since a filter that will not seat fully can cause repeated false readings
- Run a short rinse-only cycle after cleaning to see whether the code returns
- Check for any burnt smell or scorch marks near the heater, which would call for professional attention rather than another cycle
Many 1E occurrences clear once the filter is properly cleaned and reseated, since a partially blocked sump changes water flow enough to confuse the sensor. If cleaning does not resolve it, or if the code reappears within the first few minutes of a cycle, the heating circuit or its connector is the more likely problem, and that repair involves handling a live electrical component that should not be tested with the unit plugged in. Persistent 1E after a clean filter is a good reason to have the board and heater wiring checked rather than continuing to run cycles.
