The **C06** display on a Samsung POWERbot robot vacuum points to **obstacle sensor dirty/blocked**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. 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 **C06**. Search normalization stores it as **C06** while preserving the characters a homeowner actually sees.

Quick answer
Obstacle sensor dirty/blocked.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so C06 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
When the C06 condition is present, the appliance can refuse to start or continue a cycle.
C06 can be accompanied by this pattern: a door, lid, divider, or latch may not be recognized as closed or locked.
Depending on the exact model, the code can return immediately when the appliance reaches a door-safety verify.
The C06 display becomes more meaningful if c06 appears and POWERbot can stop cleaning until the reported condition is corrected.

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 open and close the door or lid firmly without forcing it.
For C06, start by doing this: remove clothing, racks, cookware, packaging, or debris that can interfere with closure.
Before opening any service area, verify the visible latch/strike area for obstruction or damage without bypassing the safety interlock.
The next non-invasive check is to if water is trapped in a washer or dishwasher, resolve the drain condition before trying to force the door open.
As an external check for C06, turn the robot off using the emergency/power switch before removing debris.
The next non-invasive check is to check the brush, wheels, sensors, dust bin, or battery only as indicated by the code.
Important safety warning. Safety takes priority over clearing C06. Turn the robot off before clearing accessible brush, wheel, bumper, or sensor obstructions. Do not work around moving parts while powered.
Get help
When to request repair service
Request service if the door closes normally but the code returns, the latch will not release safely, or diagnosis requires testing the interlock, wiring, or control circuit. In a service visit for C06, model-specific testing should follow the obstacle sensor dirty/blocked circuit rather than treating the code as proof of one failed part.
Book your repair
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 **C06** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
Continue only if the appliance is otherwise safe and the owner-level checks are appropriate. Stop for leakage near electrical parts, smoke, burning odor, arcing, gas concerns, repeated breaker trips, uncontrolled heating, or unsafe temperatures.
No. **C06** 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 C06** separate from same-looking codes used by other Samsung appliance families.
