Samsung dishwasher 1E: Meaning depends on the wash system

Documentation checkedBy ErrHiveUpdated October 28, 2026

THE SHORT ANSWER

Meaning depends on the wash system.

Samsung assigns 1E/IE different meanings: filter-flow trouble on WaterWall models, or an overheating condition on rotary models. Identify the family first.

First safe check

Check the model manual to determine whether the machine uses WaterWall or rotary spray arms.

Applies to

Samsung dishwasher families covered by the cited US guidance. Match the full model number and exact display; this is not an exact-model compatibility claim.

Before you start

Let the interior cool before reaching inside. Watch for sharp debris. Leave electrical, heater and pump access to a qualified technician.

Use the checkboxes to keep track as you read. Stop at any warning or step that does not match your appliance.

Use the correct branch
For WaterWall, follow the manual to clean the fine filter. Do not apply this filter-only interpretation to a rotary model.
What to note
The action matches the wash-system design.
Treat rotary overheating separately
For a rotary model, follow its documented HC/temperature procedure or contact Samsung if the family is uncertain.
What to note
A heat warning is not mistaken for simple dirt.

THE DETAILS MATTER

Scope & troubleshooting notes

How to interpret this result

This is deliberately one page with two explicit branches. A universal claim that 1E always means a clogged filter would be unsafe on a model where the manufacturer assigns it a heat meaning.

YOUR NEXT DECISION

When to stop and get help

Request service if the correct model-specific procedure does not clear the code, or if the model family cannot be established.

Record what you see

Keep the full model number, exact displayed code, and your observations together for the next conversation.

Use the right support

Contact the manufacturer or a qualified appliance technician when the guide calls for service.
