Slow pulsing orange light and not charging

[bebios]

Hi all,

Need some help and hopefully be able to repair my roomba 570 charging issue.
My roomba is having a slow pulsing charging light for a few hours then shows an error 7 charging fault. With the battery removed, the slow pulsing orange light persists.
Anyone knows what are the possible components in the charging circuit have failed?

Thank you all so much.

You need to replace diode D58.

Luckily I have a spare board and I can use the diode from there. Will try it.. thanks so much !!

Hi.. just to update. Diode D58 seems to be ok.. swapped another diode in and the problems still persists. Any other suggestions would be greatly appreciated. Thanks a million!

I am wondering what is powering your Roomba with the battery removed.

Hi, with the battery removed and robot plugged in the charger, it does not seem to sense that the battery is out, and just continue pulsing orange.. very strange.

Without a battery installed, I would expect your Roomba to immediately give a charging error 1, no battery installed.
The Roomba verifies there is a thermistor in the circuit, Qaud op amp U8, A3.
