Possible Causes
How to Fix / Troubleshooting
Safety first: Disconnect the charging station from mains and switch the mower OFF. Remove the battery if accessible according to the user manual.
- Check operating conditions: Make sure the mower is used within the maximum slope specified in the Parkside manual (often 20–35%). Avoid steep edges and holes that can trigger tilt.
- Inspect wheels and chassis: Check for damaged drive wheels, missing rubber treads or loose wheel hubs that can cause sudden tilting or vibration. Replace worn wheels.
- Access tilt sensor: Remove the top cover. The tilt sensor on Parkside robot mowers is typically a small module or PCB fixed to the chassis, sometimes near the center. Verify it is firmly screwed down and not hanging loose.
- Clean and reseat connectors: Unplug the tilt sensor connector from the main control board, inspect for corrosion or moisture, clean with electronics contact cleaner, and reconnect firmly.
- Calibration/reset: Some models allow a sensor reset by powering OFF, placing the mower on a perfectly level surface, then powering ON and waiting 30–60 seconds before pressing START. Refer to the specific Parkside model manual.
When to replace: If E2 appears immediately on level ground after these steps, the tilt sensor module is likely defective and should be replaced.
