iRobot Roomba 780 Charging error 5 - Bad Capacitor

I was having problems with charging error 5 on Roomba 780. Same thing with new batterie. Tried resetting, this and that… nothing helped. I even measured voltage from the PSU and compared it with another and the voltage was OK, but clearly the problem was when PSU is connected to a load. At last I opened the PSU. The problem was a bad capacitor in power supply. It had a hole on the top like someone punctured it, usually they leak or get buffed but this one didn& I also don&understand why they use those cheap Chinese no name capacitors on a Roomba which is not particularly cheap device. Wanted to make this video only because I’ve found tons of forum threads on Roomba charging errors and didn’t find much about power supply causing them. Sorry for bad footage.
