Possible Causes
Clogged auto‑empty channel, Full or blocked bag in SilverCrest base station, Failed base suction motor, Communication error between robot and base
How to Fix / Troubleshooting
Safety first: Unplug the auto‑empty base before opening it. Avoid touching internal mains wiring.
- 1. Check base bag: Open the SilverCrest base station and inspect the dust bag. Replace it if full or torn.
- 2. Clear channels: Inspect the air channel from the robot's docking port into the base. Remove any clogs of dust or debris.
- 3. Clean robot port: Wipe the robot's auto‑empty port and gasket to ensure a good seal.
- 4. Test base motor: Plug the base back in and trigger an empty cycle from the app or robot. Listen for the base suction motor. If it does not run, the base motor or power board may be faulty.
- 5. Service base: If E20 persists, the SilverCrest auto‑empty base station suction motor or control board likely needs replacement.
