Xiaomi Batteries are not reliable.
1. Check voltage on the dock. It must be 20V.

If you don't have a guarantee.
1. Check all connections, like battery - PCB.
2. Remove the battery and check voltage between red and black wires. It must be 14-16V. Connect any incandescent lamp 12V, 10-20W. The test lamp must light.
3. If there is no light you can disassemble the battery and test all 18650 batteries inside it.

Return it back then. Don't waste your time and money.
I'm pretty sure the battery is faulty.

You can't disassemble it without losing a warranty.

Yep, ask the seller. Maybe the dock isn't giving output because can't recognize the robot itself is close to it. That means a Lidar issue.
Lidars and batteries are flaws of this product.

Try to move the robot and dock station to another place that's free of any obstacles.

Make sure the lidar is fine. If you have an IP camera with infrared LED you must see something like this (laser's dots on the walls): https://www.youtube.com/watch?v=13IqEXVoZDE

If the robot's lidar is working and robot's is cleaning, moving, navigating then possible sources of issues are (sorted by probability):
1. Malfunction battery.
2. Malfunction dock station.
3. Malfunction mainboard.

Or bad contacts (Dock, battery-MB etc).

The problem is if you disassemble dock or battery you may lose your warranty.
At least you can consider removing warranty seal accurately like here: https://www.youtube.com/watch?v=KGcNS5g9ygg
The same about unscrewing. Don't leave tracks on screws.

One last moment. Move the robot to your dock station as close as possible or even fix it on the dock by your hand and connect any 12V 5-10W incandescent lamp to the dock's contacts (use any small magnets to fix wires on the contacts). The lamp must light. I think the lamp must be attached initially.

Assembly your own battery or find an alternative replacement for it (14.4V Li Ion Battery).
I built my own battery and don't care about it anymore.
