Port sensor has detected an unexpected error during operation. The reason for this might be that the port sensor is damaged.
Follow the steps below to solve the issue
Step 1
For safety, make sure that the red error light above the "Retry" button is lit. The port will not move until the Retry button is pressed, so it is safe to handle the bin while the error light is on.
Step 2
Inspect the port sensors.
If you notice any physical damage on the sensors, contact your support provider.
Do not try to repair the sensor yourself!
You cannot use the port until the sensor is repaired.
