3E on US models
The incoming water is too hot. That is how Samsung’s US guide explains 3E, naming it a high temperature water supply error.
The check
Verify the hot water supply is not set higher than 176°F.
If the setting is lower and 3E still appears, request service.
Codes next door
Samsung’s Australian list groups 3C and 3E, so 3C is the pump entry. 4C is another water supply error, concerned with pressure or temperature.
Dishwasher service in San Francisco
A Samsung dishwasher in San Francisco still reporting 3E after the supply check is a job for Samsung dishwasher repair, or ring (415) 969-6153. Give us the code, your model number and the supply setting you found.
Model compatibility: Samsung reuses 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.
