Robot mower stops and displays E02 shortly after leaving the charging station

Safety first: Unplug the charging station from the mains before touching any contacts. Keep the area dry.

• Step 1 – Verify power supply: Check that the Sunseeker power adapter is firmly plugged into the wall and the charging base. Confirm the LED on the adapter or base is lit.
• Step 2 – Clean contacts: Inspect the metal charging contacts on both the mower and the station. Clean grass, dirt, and oxidation with a dry cloth. Do not use abrasive tools or liquids.
• Step 3 – Check station placement: Ensure the charging station is on a level, firm surface and that the mower can dock straight without climbing or twisting. Misalignment can cause poor contact and E02.
• Step 4 – Inspect dock wiring: Follow the low-voltage cable from the adapter to the station and any internal connectors. Look for cuts, crushed sections, or loose plugs.
• Step 5 – Test with another outlet: Plug the adapter into a different outlet to rule out supply issues.

If E02 continues, the charging station control board or contact assembly may be defective and should be replaced.
