Quick answer
On a Samsung dishwasher, 1E means different things by model: on WaterWall models, a clogged filter; on rotary spray arm models, a high temperature heater error. On a WaterWall, clean the fine filter at the bottom of the tub.

- On a rotary spray arm model, 1E means high temperature: if you notice a burning smell or warped plastic, cut power and do not use it until inspected.

What a technician must be able to justify
A technician is coming
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Diagnosis by wash system
What they doOn a WaterWall, the technician checks the filter, sump and water path; on a rotary model, they measure the heater, its control and the temperature sensor against Samsung specification.
They must show youwhat was found and the measurements against specification.
In writingthe type of unit, what was checked, the result and the reference of any replaced part.
Test cycle after the repair
What they doThe technician runs a normal cycle and checks 1E does not return.
They must show youa full cycle with no code.
In writingthe test, the result and the date.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Type of dishwasher
- Who:
- you.
- How:
- check your manual or model page to see whether it is a WaterWall or a rotary spray arm dishwasher.
- Result that matters:
- knowing which of the two 1E meanings applies to your unit.
- If it is a WaterWall:
- 1E points to the filter; go on to clean it.
- If it has rotary arms:
- 1E is a high temperature heater error; go on to the restart and normal cycle.
- Evidence to keep:
- note the model and type.

What it means
Samsung gives 1E (or IE) two meanings depending on the wash system. On WaterWall models it is a clogged filter error: water is not passing through the filter. On rotary spray arm models it is a high temperature heater error, like HC: overheating inside the unit. For WaterWall, Samsung asks you to clean the fine filter at the bottom; for rotary models, to power cycle and run a normal cycle with detergent. If it persists, in both cases, service. The code does not name a failed part.
