Possible Causes

Dirty ultrasonic sensor lenses, Water ingress into sensor, Misaligned sensor bracket, Failed ultrasonic sensor module

Safety first: Turn OFF the mower before cleaning sensors.

Clean sensor faces: Wipe the ultrasonic sensor openings on the front of the mower with a soft, damp cloth, then dry thoroughly.
Check for damage: Inspect sensor housings for cracks or signs of impact.
Avoid water jets: If the mower was recently pressure‑washed, allow it to dry completely indoors for 24–48 hours.
Test operation: Restart the mower and observe behavior in open space. If E016 appears even without obstacles, the sensor module may need replacement.
