Roomba 531 charging error 3, new battery

Postby torbenc » June 19th, 2018, 7:03 am

Hi

My Roomba 531 started to give me charging error 3, and sometimes it helped to take out the battery, clean the terminals and re-insert it.
It got worse and worse, and suddently the battery seemed dead. And I coulden't even turn on the Roomba.

I replaced the battery, but get a charging error 3 constantly now.

I have cleaned the terminals, and bend dem slightly upwards
I have done a reset of the Roomba
I have used both the dock and the side charger port

Still same error.

Only thing I haven't tried, is to leave the charger plugged in, for some days. It is flashing red, when the charger is plugged in

You could have searched Charging Error 3 and found a lot of info.

So what makes you think I haven't searched? My post clearly states that I have made attemps to make it work - Do you think I have invented those things my self?

You can catch a lot more bees with honey than you can with vinegar.

From my first post.

I also re-soldered all battery terminals connections, and cleaned the PCB.
U8 has no visual defects on any legs.
