You might notice issues with your charging performance over time. Difficulty plugging the connector into your vehicle or a loose fit can indicate wear. Frequent disconnections during a charging session also signal a problem with the cable or its connections. If you find any damage, stop using the charger and call a professional.
Checking and Resetting Error Codes
Your EV charger communicates through lights, beeps, or on-screen messages. Sometimes, a simple DIY fix is all you need.
A basic reset can often solve temporary glitches. You can do this by turning the circuit breaker off for a minute and then turning it back on.
However, persistent error codes point to a deeper issue. While you can look up codes in your user manual, interpreting them can be tricky. For example, some JuiceBox models use beep codes to report problems.
| # of Beeps | Error Type | Common Solution |
|---|---|---|
| 1 (Repeating) | GFI AutoTest Failure | Unplug the unit for 30-60 mins; power cycle the breaker. |
| 3 (Short) | GFI Trip | Unplug the charger from your car to reset the trip count. |
| 4 (Short) | OverHeat | Move the charger to a cooler, well-ventilated area. |
| 5 (Short) | Relay Stuck Closed | Switch off the circuit breaker and contact support immediately. |
If a simple reboot does not clear an error, you should not attempt further repairs. Trying to fix an internal fault without the right knowledge can damage the unit or void your warranty. An electrician can diagnose the root cause and fix it safely.
Electrical Testing for Voltage and Amperage
This task is for professionals only. You should never attempt to test the electrical components of your EV charger. The high voltage is extremely dangerous and can cause severe injury or death. This is a critical part of ev charging maintenance that requires an expert.
A licensed electrician uses specialized tools to measure your charger’s electrical performance. These tools are expensive and require training to use correctly.
