For the Samsung Washer families covered by the source set, **A2** means **factory test mode is active**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. 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 **A2**. Search normalization stores it as **A2** while preserving the characters a homeowner actually sees.

Quick answer
Factory test mode is active.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so A2 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Signs
Symptoms you may notice
On affected Samsung washing machine models, the display appears while the appliance is otherwise able to respond normally.
The A2 display becomes more meaningful if the message can be tied to a mode, test, reminder, setup state, or protective condition rather than a failed part.
A symptom that fits A2 is that normal operation may resume after the documented mode or condition is cleared.
When the A2 condition is present, a2 appears on the display while the appliance reports: Factory test mode is active.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
With A2 recorded, confirm the exact display characters and appliance model before treating the message as an issue.
The next non-invasive check is to check the user-facing setting, mode, door, filter, container, or setup condition named by Samsung for this display.
Before requesting service for A2, use the model-specific manual to clear the status; avoid repeated resets if the message reappears unexpectedly.
A safe owner-level check is to record the code and the cycle stage where it appears.
As an external check for A2, verify owner-accessible water supply, drain hose/filter, load balance, door, detergent, or power only when relevant.
Before opening any service area, power-cycle once only where Samsung's guidance recommends it; if the same code reappears, move to model-specific diagnosis.
Important safety warning. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips. For A2, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.

When to request repair service
Once A2 has returned after the safe checks, Service is not automatically required. Request diagnosis only if the status cannot be cleared as designed or normal operation does not resume. Preserve any accompanying noise, water level, temperature, or operating-stage details for the technician.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
A single documented power reset can help after an external condition or power event is corrected. If **A2** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
The display can be normal in the documented context. If **A2** appears unexpectedly, cannot be cleared, or prevents normal operation, then the issue deserves diagnosis.
Treat **A2** as a starting point, not a replacement instruction. Wiring, feedback signals, operating conditions, and electronic controls can mimic a failed component.
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 **Washer A2** separate from same-looking codes used by other Samsung appliance families.
