The **SR** display on a Samsung dishwasher points to **drain error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. 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 **SR**. Search normalization stores it as **SR** while preserving the characters a homeowner actually sees.

Drain error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so SR may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
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. If resolving SR would require energized internal access, that is the point to hand the diagnosis to a qualified technician.
If the owner-accessible checks do not clear SR, If the accessible drain path is clear but the code returns, the pump, internal hose, water-level sensing, wiring, or control may need model-specific testing. The repair should confirm the monitored function and its feedback before any board or component is condemned.

Drain error.
One controlled restart is reasonable after correcting an obvious external issue. A recurring **SR** 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 **SR**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
Treat **SR** 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 **Dishwasher SR** separate from same-looking codes used by other Samsung appliance families.
