Possible Causes
Dock power adapter failure, Charging contacts bent or dirty, Internal charging PCB fault, Battery protection circuit open
How to Fix / Troubleshooting
Safety first: Unplug the dock before inspecting its contacts. Do not short the charging contacts.
- 1. Verify dock power: Check that the dock's LED is on. Test the power adapter with another compatible device if possible.
- 2. Clean and inspect contacts: Wipe the metal contacts on both the dock and robot. Ensure they are not bent, corroded, or recessed.
- 3. Align robot on dock: Manually place the robot on the dock, ensuring the contacts align and the charging indicator on the robot lights up.
- 4. Try direct adapter (if supported): Some models allow direct plug-in charging. If available, test this to isolate whether the dock or robot is at fault.
- 5. If E19 continues and no charging occurs: The internal charging PCB or main control board may be defective. Professional service is recommended, as this involves high-current circuits.
