Robot mower displays E19 and may not dock correctly or may overshoot the charging station.

Safety first: Disconnect mains from the charging station before adjusting it.

• Check station placement: Ensure the charging station is level, firmly anchored, and the entry path is straight and clear for at least 2–3 meters.
• Inspect guide wire: If your Kress model uses a guide wire, verify it is correctly connected to the station terminals and not broken along its length.
• Clean docking sensors: Wipe any IR windows or optical sensors at the front of the mower and station with a soft cloth.
• Check contact alignment: Manually dock the mower and confirm that the charging contacts line up and press firmly together.
• Persistent E19: The Docking Sensor Board or guide wire output in the station may be faulty and require professional service.
