For the Samsung Dishwasher families covered by the source set, **1E** means **model/region dependent: clogged filter / water not passing through filter; high-temperature heater / overheating error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **1E**. Search normalization stores it as **1E** while preserving the characters a homeowner actually sees.

Quick answer
Model/region dependent: Clogged filter / water not passing through filter; High-temperature heater / overheating error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 1E may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this code means
For the Samsung Dishwasher families covered by the source set, **1E** means **model/region dependent: clogged filter / water not passing through filter; high-temperature heater / overheating error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **1E**.

Signs
Symptoms you may notice
One clue that supports the 1E diagnosis is that heating can be weak, absent, excessive, or stop unexpectedly.
Depending on the exact model, the appliance can pause when the control detects an unsafe or implausible temperature condition.
While 1E is active, drying, washing, cooking, or defrost performance may change depending on the appliance.
The 1E display becomes more meaningful if 1E appears during the dishwasher function associated with clogged filter / water not passing through filter.
While 1E is active, the cycle may stop, drain, fail to fill/heat, or repeat a stage.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
To rule out an accessible cause, confirm the selected cycle or cooking mode is supposed to use heat.
Before opening any service area, verify airflow, vents, filters, water supply, or door closure when those conditions affect temperature.
As an external check for 1E, allow the appliance to cool before any owner-accessible inspection.
The next non-invasive check is to do not open energized high-voltage or heating sections.
As an external check for 1E, record the code before resetting.
A safe owner-level check is to check water supply, drain path/filter, door, detergent/suds, and visible leaks only when relevant.
Important safety warning. Stop use for active leakage near electrical parts, burning smell, or repeated breaker trips. Do not defeat leak or door-safety switches. For 1E, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.

When to request repair service
If the owner-accessible checks do not clear 1E, A returning heating/over-temperature code after external checks requires model-specific testing of sensors, heaters/ignition, relays, wiring, airflow, or control electronics. The repair should confirm the monitored function and its feedback before any board or component is condemned.

Model/region dependent: Clogged filter / water not passing through filter; High-temperature heater / overheating error. Check the model-specific interpretation section below because Samsung publishes more than one verified meaning for this appliance+code key.
You can try the one reset Samsung documents for the model, but **1E** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **1E** should not be ignored if performance is deteriorating or the display keeps returning.
No. **1E** 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.
Official Samsung support itself assigns different meanings to this code in different model/region contexts, so the exact model number matters. This page therefore keeps **Dishwasher 1E** separate from same-looking codes used by other Samsung appliance families.
