Th!nk City original charger - 4 blinks on 2 diodes

[Damir]

My Th!nk City original charger worked fine, until I wanted to test out the Quick Charge - and it worked. I only tried it once, for about an hour. However, since that day, the charger's "Power Fault" and "Car Link Fault" diodes start blinking 4 times immediately after I disconnect the charger, either from the car, or from the main outlet. It doesn't matter if it charges the car completely for hours, or just minutes. or when it's connected to a car or not. While the diodes blink I am not able to charge the car. It needs a couple of hours to "reset?" or "cool down?" and then it works again. The charger is not hot, rather only slightly warm on touch.

What could be the reason for this?

Is there a schematic of the charger that I could forward to my electrician?

You say that if the charger is disconnected from the main outlet the leds are still on and blinking ??

No, I was just pointing out that the order of disconnecting it, first from the car or the main outlet, doesn't matter.
