Samsung Dishwasher 1E / IE — Filter clogged / heater fault

Samsung Dishwasher · Error code 1E

What 1E Means

On Waterwall models, 1E (also shown as IE) means water is not passing through the filter — the fine filter is clogged. On rotary-spray models the same code can indicate a high-temperature heater error.

Symptoms

  • 1E or IE on display
  • Cycle stops with standing water
  • Dishes come out dirty
  • Wash spray weak or absent

Common Causes

1
Clogged fine filter at sump

Food debris, grease, glass shards blocking the fine mesh under the lower spray arm.

2
Clogged pump inlet

Debris past the filter lodged in the circulation pump inlet.

3
Heater short or open (rotary models)

Heating element failed or wiring fault triggers high-temp heater fault.

4
Failed temp sensor

Thermistor reads out of range and trips the heater protection.

How to Fix It

  1. Power off at the breaker for 1 minute, restore power and try a Normal cycle to confirm the code returns.
  2. Pull the lower rack and remove the filter assembly (twist counter-clockwise on most models).
  3. Rinse the fine and coarse filters under hot water with a soft brush; clear the sump opening of debris.
  4. Reinstall the filter — make sure it is fully seated and locked or the dishwasher will throw codes.
  5. Run a Self Clean / hot rinse with no dishes to verify the code clears.
  6. If code persists on a rotary model, test the heater for continuity (~10–40 ohms) and the thermistor; replace if open/shorted.
