Samsung Dishwasher 1E Error: Causes & Fixes

On a Samsung dishwasher, error code 1E (also displayed as IE) has two different documented meanings depending on the wash mechanism: on Waterwall models it means water is not passing through the filter, and on Rotary (non-Waterwall) models it means the same high-temperature heater condition as code HC (the dishwasher is too hot inside).

What Samsung dishwasher 1E means

Samsung's dishwasher error-code reference lists several codes with different meanings from 1E/IE that readers sometimes confuse with it: 4C/4E is a water-supply error ('the dishwasher is not getting water at the pressure or temperature that it needs'), 5C/SC/5E/SE means the dishwasher can't drain, LC/LE is a leak-sensor error that turns the dishwasher on and prevents it from turning off, and 3C means the pump has failed.

Before you work on your dishwasher

  • Power: Unplug the dishwasher or switch off its circuit breaker before removing panels or touching wiring.
  • Water: Turn off the water supply valve before disconnecting hoses or the inlet valve.
  • Heat: Water and the heating element can be hot right after a cycle; let the dishwasher cool first.
  • Sharp debris: Wear gloves when reaching into the filter or sump; broken glass often collects there.
  • Stop: If you smell burning, see smoke or sparks, or find water near wiring, switch off the breaker and call a technician.
  • Disconnect power before accessing internal dishwasher parts: Unplug the dishwasher or switch off the circuit breaker that powers it before removing panels, the filter, or the drain pump cover, or before reaching into the sump.
  • Hot water and steam scald risk: Open the dishwasher door carefully during or right after a cycle. Hot water or steam can escape and cause burns; wait until water noises stop and steam subsides before fully opening the door.
  • Sharp debris near the filter and drain pump: Wear gloves and use caution when removing the filter, pump cover, or other parts for cleaning; broken glass or other sharp debris can collect near the drain pump impeller.

What causes Samsung 1E

  1. Rotary model overheating (same as HC high-temperature heater error): On Rotary (non-Waterwall) models, 1E/IE indicates the same high-temperature heater condition as error code HC: the temperature inside the dishwasher is too hot. Difficulty 1/5.
  2. Waterwall fine filter/sump blocked, water not draining through the filter: On Waterwall models, 1E/IE appears when water is not passing through the fine filter, most often because the filter and sump are blocked and need cleaning. Difficulty 1/5.
