Roomba 531 lights work but not charging

Hi,

I have an iRobot roomba 531 that doesn’t seem to charge.
I replaced the battery of that roomba some months ago because the previous battery was old and lost its charge rather quickly.
Power cable and docking station are still original, those have not been replaced.
The replacement battery worked fine for some months.
Now when the roomba is put in the docking station the light at the top flashes orange/amber very quickly for about a minute and then the light goes to green and stays green.
However when I remove the roomba from the docking station, the light goes off immediately and if I press the button to let it run, it doesn’t start.
I’ve also tried plugging in the power cable directly to the roomba (so no docking station) and I see the same thing: the light at the top flashes orange/amber very quickly for about a minute and then the light goes to green and stays green. If I then unplug the power cable the light goes off immediately and if I press the button to let it run, it doesn’t start.
I have tried pressing dock and spot button at same time to trigger reset and then let it charge, but that doesn’t help
I have tried letting the roomba charge for 24 hours, but that doesn’t help.
I opened up the roomba again and looked at the battery and cleaned the contacts a bit, but found nothing odd and that didn’t help.

Any advice, things I can try?

Hello @Neverwinterx !

Sorry to hear about your problem. I was looking and I found something you could try here:

It is my gut feeling that you have some battery problems here. Go ahead and try this: If your Roomba is indicating a full charge, but it only runs for 15 minutes when you press clean (not running in your case), you need to reset the charging system. You can do this by removing the battery from the robot and unplugging the charger from the wall and robot. Please hold the power button down for 30 seconds. It is to be done with the battery out and the charger disconnected. This will the capacitor circuits of the Roomba. After this, replace the battery and charge the robot If that does not work you might just have to get a new battery.

Let me know if this help you! :grin:
