If a Samsung dryer shows **2E**, the verified Samsung meaning in this research set is **voltage / power-supply error**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. The exact stage when the code appears can be as important as the characters themselves. Note whether it happens at startup, during fill, heating, cooling, draining, spinning, drying, or after a power event. The recorded display form is **2E**. Search normalization stores it as **2E** while preserving the characters a homeowner actually sees.

Quick answer
Voltage / power-supply error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 2E 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
If a Samsung dryer shows **2E**, the verified Samsung meaning in this research set is **voltage / power-supply error**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. The exact stage when the code appears can be as important as the characters themselves. Note whether it happens at startup, during fill, heating, cooling, draining, spinning, drying, or after a power event. The recorded display form is **2E**. Search normalization stores it as **2E** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
One clue that supports the 2E diagnosis is that the appliance can stop, restart, or refuse a high-load function.
While 2E is active, the code can appear after a surge, brownout, outage, incorrect supply, or frequency problem.
When the 2E condition is present, some models preserve the display even when one required power leg or voltage range is abnormal.
One clue that supports the 2E diagnosis is that 2E appears and drying can pause or performance may change because of voltage / power-supply error.
A symptom that fits 2E is that heat, airflow, motor, drainage, door, or sensor behavior may be affected depending on the code family.

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 breaker has not tripped and the appliance is connected as specified by Samsung.
As an external check for 2E, if the event followed an outage or surge, perform only the documented one-time power reset.
A safe owner-level check is to do not perform live mains-voltage measurements unless qualified.
To rule out an accessible cause, stop if breakers trip repeatedly, plugs/outlets overheat, or there is arcing.
Before requesting service for 2E, record the code and whether the dryer is vented or heat-pump/ventless.
As an external check for 2E, clean/inspect lint filter, heat exchanger, water tank/drain, and external vent only when relevant.
Important safety warning. Stop for burning smell, smoke, gas odor, repeated breaker trips, or abnormal overheating. Do not bypass thermal protection. Do not bypass a safety device merely to see whether 2E disappears.

When to request repair service
Persistent power/voltage codes need the household supply and appliance power/control circuits checked safely before parts are replaced. A repeatable 2E event is more useful diagnostically than repeated resets, because it shows when the voltage / power-supply error check is failing.
Book your repair
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 **2E** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **2E** should not be ignored if performance is deteriorating or the display keeps returning.
Not automatically. Samsung error codes are diagnostic indicators, not part numbers. Confirm the circuit around **2E** before replacing anything.
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 **Dryer 2E** separate from same-looking codes used by other Samsung appliance families.
