Error code 3E
Appliance Dishwasher
Quick answer

3E is a high temperature water supply error on US models. Check the hot water setting.

Model compatibility: Samsung can reuse or reformat codes across series and model years, so 3E may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

3E on US models means incoming water is too hot.

3E for US models

  • Meaning: high temperature water supply
  • Cause: the water is too hot

Check this

Look at the home’s hot water supply and confirm that it is not set above 176°F. A supply below that limit with the error still showing means it is time to request service.

Codes to compare

  • 4C – water pressure or temperature insufficient
  • 3C – pump failure in the US guide
