Possible OBC failure

I have a 2020 ELW that I fear may have a failed OBC. After my last ride for the season a few weeks ago, I parked my bike in my garage and was charging it up to meet the range specified for long term storage in the manual. Around approximately 46% I got a notification that my bike had stopped charging and the breaker had tripped for my garage. I reset the breaker, unplugged the bike but it will no longer charge. When I plug it in, the EVSE starts blue as normal but turns to red in moments. I’ve tried different outlets in my garage, clearing the fault codes, and checking the fuses to no avail. I haven’t yet called the dealer as I have a few months of winter to do that if need be but I’m trying to see if I can avoid a trip there if possible. Anything I’m missing Or possible solutions? I have attached the codes for my bike. The first is before I tried clearing the codes and the second is more recent.

I have not yet been able to try a different evse. The only person I know who has one lives a fair distance away. I don’t think that’s the problem as the blue light indicator on mine acts as normal but consider it a possibility.

That’s a possibility. Unfortunately the nearest charger is 20 min away and i won’t be venturing out on my bike for a while due to the sand and salt on the roads from recent weather events. I’ll try to borrow my buddys evse and go from there.

Unfortunately I am out of warranty so I’m hoping it’s something simpler/less expensive. Fingers crossed

A couple of thoughts:
1st, according to the LiveWire service specialist at my dealer, the “H” at the end of the DTCs indicate that the code is “historic” and has resolved itself; and
2nd, have you tried clearing the codes, riding the bike (even for just a few yards/meters, and attempting to charge again?

Wishing you good luck!

havent and probably won’t be able to ride at all for the foreseeable future here even just a little. I did clear the codes once and nothing did change. The insight in the DTCS seems like good news as it may just be the EVSE. But won’t know more until I can try a different one.

Thanks for all the code info! It saves a conversation with the techs at Milwaukee HD who I were not impressed by when I talked to them this past summer.

Did you try resetting all codes and retry charging?

Yes I did try that once and received the same result where it attempted to start but got a red light from the EVSE.

You did try the EVSE on another circuit right? Had a few issues hooking to a circuit in my garage that couldn’t provide enough Amps.

I haven’t yet tried it on another circuit. I only have one in my garage and there isn’t another one i can access on my property for the time being.

This afternoon, I cleared the codes again, plugged her into the same outlet I’ve been using and she began to charge with no issue. The only change from previous attempts was I let her sit a full week untouched and I brought the EVSE inside the house in that time frame. I’ll charge her up to around 65% and go from there. thanks for the help everyone.
