I've got a version of this problem, and it's a doozy.
We have a two-week-old Siemens Versicharger, hard-wired to our garage. Used it about 9 times, successfully. On Thursday, the Versicharger wand stuck. The trigger is completely frozen--no movement. We have tried both the dashboard lock toggle button and the key fob unlock button--you can hear, feel and see a mechanism moving, but nothing changes with the charger/EVSE connection.
If this helps, my husband noted that the EVSE had a red (error) halo (operations indicator light), so he followed the steps to resolve it, and turned the breaker on and off, a couple of times. Now, we assume b/c the wand remains connected, it keeps trying to charge. Even when the battery is full, it maintains a steady green halo (which shouldn't be on if it's finished).
We have talked to the dealer, who passed us on to Nissan corporate, who says it absolutely has to be the Siemens unit. So we have spent some quality time with the Siemens rep, gone over everything he can think of. Now he has even suggested having an electrician come out and disconnect the hose, drive to the dealer and...I don't know, disassemble the entire front end to remove the charger?
The Siemens rep has been pretty reasonable, btw, this isn't meant as a complaint about them so far.
Our next step is to call the dealer/corporate again and see how doable that is and what they can do and how many $$$ this will cost us, warranty or no warranty.
So my question to y'all is: has anyone encountered this type of experience, can you offer any kind of advice? I'd be grateful for insights.
Thanks in advance.
