Samsung dishwasher 1E / IE: filter or high-temperature heater condition
Samsung says 1E/IE is model-family dependent: WaterWall models use it for restricted water flow through the fine filter, while rotary models use it for an over-temperature heater condition.

This guide follows a structured decision tree built from manufacturer troubleshooting information. It does not assume that the most commonly replaced part is the failed part, and it does not show an exact-fit replacement part unless model compatibility has been independently verified.

Appliance Verdict stops before energized electrical testing, gas-system work, sealed-system work, and other checks that can create unnecessary risk. A technician can use the model, issue, and completed checks from the interactive diagnostic as a starting point.
Repair or replace?
A diagnosis and a repair decision are different questions. Once you have a real repair quote, compare the total repair cost with the all-in price of a comparable replacement. Warranty or protection-plan coverage, appliance age, reliability history, efficiency, and likely future repairs can all matter. Appliance Verdict’s interactive result includes a transparent cost comparison rather than a black-box replacement recommendation.
