Dear all,
We’ve analysed these failures, and they are caused by a hardware defect, and even though rather coincidental, they are not caused by the recent v3.61 firmware update; and also downgrading to an earlier firmware version will not solve the issue.
The described behaviour points to a component internal to the unit that has failed.
Note that all chargers for which the v3.61 firmware update is available are still within their 5 year warranty term.
To get support, including a replacement in case necessary, there are two ways to get it resolved: either (1) contact your supplier directly, or (2) submit a Support Request. Submitting such request will also put you in touch with your supplier/dealer. On that form please check the box for a suspected hardware issue. Also include a link to this forum thread in the fault-description section.
