The **3E** display on a Samsung dishwasher points to **circulation / wash-motor error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. A display code is evidence from the control system, not a component test result. That distinction matters because a connector, supply condition, obstruction, or feedback signal can mimic a failed component. The recorded display form is **3E**. Search normalization stores it as **3E** while preserving the characters a homeowner actually sees.

Quick answer
Circulation / wash-motor error.
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
The **3E** display on a Samsung dishwasher points to **circulation / wash-motor error**.

Signs
Symptoms you may notice
On affected Samsung dishwasher models, the affected drum, wheel, brush, auger, pump drive, or mechanism can not move as expected.
3E can be accompanied by this pattern: the appliance can hum, jerk, stop, or retry the motion.
3E can be accompanied by this pattern: the code can appear when the control fails to receive expected speed or position feedback.
A symptom that fits 3E is that 3E appears during the dishwasher function associated with circulation / wash-motor error.
3E can be accompanied by this pattern: the cycle can stop, drain, fail to fill/heat, or repeat a stage.
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
With 3E recorded, remove only user-accessible obstructions from the affected moving part.
For 3E, start by doing this: do not force a locked drum, brush, wheel, or mechanism.
For 3E, start by doing this: note whether the motor attempts to start and whether unusual noise or burning smell is present.
Before requesting service for 3E, stop use immediately for overheating, smoke, or electrical odor.
For 3E, start by doing this: record the code before resetting.
To rule out an accessible cause, check water supply, drain path/filter, door, detergent/suds, and visible leaks only when relevant.
Important safety warning. When working around a dishwasher that shows 3E, keep the checks external and non-invasive. Stop use for active leakage near electrical parts, burning smell, or repeated breaker trips. Do not defeat leak or door-safety switches.

When to request repair service
A repeat motor/drive code can require mechanical-load, winding, sensor, harness, inverter, or control testing. A repeatable 3E event is more useful diagnostically than repeated resets, because it shows when the circulation / wash-motor error check is failing.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
One controlled restart is reasonable after correcting an obvious external issue. A recurring **3E** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
Short owner-accessible checks may be reasonable when the appliance is safe. Persistent **3E**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
No. **3E** tells you which condition or check the control detected. The same display can result from the named component, its wiring, a connector, a supply/airflow/water condition, or the control that reads it.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Dishwasher 3E** separate from same-looking codes used by other Samsung appliance families.
