Onboard charger capacitors failed

Sun Feb 24, 2019 9:15 am

ZEO 2012. Car on and go to driving mode. But cannot charge using AC charger or DC charger.
DTCs P3173, B2631 Sunload sensor, B2840 On board charger
Cleared errors. plugged AC charger. The car recognized the charger and started to charge. But fail after 5 seconds from the time when the AC charger plugged in.
Scan the car to get B2840 962E and P317 00C0. I did that several times, but it got the same result.
Some times, P3173 cannot clear. Several times, sometimes it gets cleared.

Tried DC Fast Charger. It went all charging sequences. But the charger did not got current request messages to inject current. So, the fast DC charger stopped working.
After that, the car showed errors B2840 962E , P317 00C0 and B29C1 9428. Tried several times, but failed.

Then disconnect the onboard charger of the vehicle and opened covers. Noticed that there are two burnt capacitors. No other burning signs.
Repairing of the onboard charger has not been guided b manufacturer, but decided to replace the burnt capacitors since the cost of even a used onboard charger is costly.
1. Has any done this before?
2. What could have caused this?
3. Will the replacement of Capacitors be successful?

I would start with the capacitors.
I'm assuming they are polarized electrolytics.
Got any numbers for the voltage and microfarads?

Thanks!
They are non Polarize capacitors. One is 1.0uF 275V LE105 and other is 3.3uF 275V LE335
My order will arrive on Friday, any further opinion?
