For the Samsung POWERbot Robot Vacuum families covered by the source set, **No batt** means **battery error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **No batt**. Search normalization stores it as **NOBATT** while preserving the characters a homeowner actually sees.

Error codeNOBATT

Quick answer
Battery error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so NOBATT 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
For the Samsung POWERbot Robot Vacuum families covered by the source set, **No batt** means **battery error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **No batt**. Search normalization stores it as **NOBATT** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
When the No batt condition is present, the appliance can stop or limit the affected function when the code is detected.
The No batt display becomes more meaningful if the same code may return at a repeatable stage of operation.
The No batt display becomes more meaningful if other symptoms depend on the model and the subsystem named by Samsung.
No batt can be accompanied by this pattern: no batt appears and POWERbot can stop cleaning until the reported condition is corrected.
Why it happens
Possible causes
varies by model — official regional/current support — Battery error
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
A safe owner-level check is to record the exact code, model number, and operating stage before resetting power.
The next non-invasive check is to complete only the owner-accessible checks described in the model manual.
The next non-invasive check is to do not replace parts solely from a display code when wiring, conditions, or control feedback can create the same result.
For No batt, start by doing this: turn the robot off using the emergency/power switch before removing debris.
The next non-invasive check is to verify the brush, wheels, sensors, dust bin, or battery only as indicated by the code.
The next non-invasive check is to restart once after the obstruction or installation issue is corrected.
Important safety warning. Safety takes priority over clearing No batt. Turn the robot off before clearing accessible brush, wheel, bumper, or sensor obstructions. Do not work around moving parts while powered.

When to request repair service
If the owner-accessible checks do not clear No batt, If the code returns after the documented basic checks, request model-specific diagnosis of the affected subsystem. The repair should confirm the monitored function and its feedback before any board or component is condemned.

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 **No batt** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
Do not keep operating the appliance through a hazardous symptom just to see whether **No batt** clears. If there is heat, water, electrical, gas, or food-safety risk, stop and arrange diagnosis.
No. **No batt** 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 **POWERbot Robot Vacuum No batt** separate from same-looking codes used by other Samsung appliance families.
