myenergi zappi zappi v2 and v2.1 fault codes
The generation the published fault code table covers, in both tethered and untethered form. The untethered units are the ones that can show lock and cable faults.
Codes on the zappi v2 and v2.1 follow the same myenergi zappi scheme as the rest of the range. Where a code behaves differently on this generation, the code page says so.

Every published myenergi zappi code. Open a code to see which models and years it applies to.
- PEN FaultCode 29. The protection against loss of the supply earth-neutral conductor has operated, and myenergi tell you to remove the fault before resetting.Stop — call an engineer
- PE FaultCode 25. myenergi say the earth is either disconnected or its impedance is too high — a problem in the installation rather than in the charger.Stop — call an engineer
- SelfTest FailedCode 27, searched as A27. The built-in protection devices could not be tested, or failed the test, before a charge. myenergi’s action is a reset; they do not say it cannot be repaired.Get it checked
- Charge BlockedNot a fault. The car keeps asking to charge after it already reported complete, and the zappi has stopped answering.Usually simple to fix
- Lock FailureCode 23, and the fix is counter-intuitive: push the plug further in to release it. Untethered zappis only.Get it checked
- OverheatingTwo stages, both published: wavy lines over the zappi icon mean thermal limiting with reduced output, and the Overheating! message means the output is off. Ventilation is the remedy and charging resumes on its own.Get it checked
- Contactor FaultCode 28. myenergi say a relay inside the unit has welded, and that a second relay is holding the supply to your car isolated. Their action is one reset; if it returns, contact them.Get it checked
- Bad Voltage RangeCode 31, shown with Over Voltage or Under Voltage. The mains supply is outside the range the zappi will charge on, so it has disconnected the car. The fault is upstream of the charger.Get it checked
- Comms FaultCode 26: the zappi cannot talk to its own built-in protection components. One reset is the published action; a repeat is a hardware fault inside the unit.Get it checked
- Pilot problemThe zappi cannot read the control pilot signal on the cable to the car. It retests every five seconds; myenergi’s advice is to unplug, check the plug for dirt and try again.Usually simple to fix
- Output FaultCode 24: the zappi has measured voltage on its output when the output should have been off. The unit stays off; reset once, and if it repeats it is a call to myenergi.Get it checked
- OverloadCode 30: the car is drawing more current than the zappi offered, so the output has been switched off. Reset, and if it repeats the question is the car, not the charger.Get it checked
- Voltage MismatchCode 32: the zappi’s controller and its protection components measured the output voltage differently. A disagreement between two safety measurements, so the unit stops.Get it checked
- Unknown CableAn untethered zappi could not identify the rating of the cable plugged into it. Only genuine 13, 20 or 32 amp Type 2 cables are recognised; the unit retests after five seconds.Usually simple to fix
