after several weeks of no problems , using L2 on our LEAF, the charger[50A basic model] has quit working.  it looks fine, the car beeps once when plugged in but no charging takes place.  I plugged in the Nissan 110V charger and it works fine, so it isn't the car.  in settings I set timer to NO.  I tried L1, that doesn't do anything either.

so, where do I start debugging?  one issue I have is that 2 of the six screws that hold the case on seemed to have stripped out and won't come off.  I remember initially when I assembled it they felt odd going in.

under settings there is a relay check.  is the relay supposed to kick in during the settings, or just when plugged in initially?

the cable must have slid down and the pilot wire pulled loose.  I shouldn't have had it such a tight fit originally.

even after sawing 2 screws off I still couldn't remove the screws using pliers to grab them, so gave up on them.  the box is in the garage anyway.  a longer harness to the display would be nice for cover removal.

I had a similar symptom from an entirely different cause, and resolved it. I'll mention it here in case someone is searching the topic.

In my case I tried to charge my Nissan Leaf from an OpenEVSE charger configured for a full 80 amps capacity. Apparently it is a known fact that the Leaf doesn't like this -- although configuring the EVSE for 75 amps works fine, solves the problem. And also there is supposed to be a dealer firmware upgrade, though I havent followed up on that.
