I’ve recently been having issues with my home installed L2 charger, it either will not start charging, or will start, then stop with an error that says something similar to “Charging Operation Interrupted”. I verified that it’s the charger by using my portable L1 charger, which has no issues charging (other than being much slower, of course).

My first thought is that the connection has become dirty with time, and I need to clean it. But I’m having trouble finding something that would allow me to do so.

Is there a special cleaning tool that I can purchase to attempt to clean the charging head? Otherwise, I’ll need to purchase a new charging cord, as in my area hiring an electrician would essentially cost more just to get a diagnosis of what’s wrong (and then if the diagnosis was that the cord is dead, I’d have to buy a new one anyways).

Any extra ideas are appreciated, I bought this ChargePoint charger back in 2017.
