In case of a problem, the VOOL Charger will illuminate the red LED lights and the charger app will display a further error description. Potential causes and solutions are brought in the following table. If you cannot find a solution to the problem, contact the [email protected]
There are two separate sets of numbers, so check which one you have. The table below is the one printed in the VOOL Charger user manual, numbered 01 to 11. The charger's own software reports a different and much longer set of status codes — 2, 3, 4, 13, 101, 200 and so on — and those are what the app, the portal's health status and support will quote at you. They are listed in VOOL charger status codes and what they mean. If your number is above 11, or you read it off the app or the portal, use that page — the two lists do not line up, and code 10 in one is not code 10 in the other.
Error codes printed in the user manual
Error code | Issue | Troubleshooting |
01 | The charger received inaccurate information from the vehicle. | Switch off the charger from the main switch. Then switch it back on. If the error persists contact the manufacturer at [email protected] |
02 | The sensor of the residual current is not working. | Contact the manufacturer at [email protected] |
03 | There is an internal malfunction in the charger. | Contact the manufacturer at [email protected] |
04 | The residual current is discovered in the charging circuit. | Switch off the charger from the main switch. Then switch it back on. If the error persists contact the manufacturer at [email protected] |
05 | The charger has detected a malfunction in the vehicle. | Turn off the charger from the main switch, and turn it right back on. If the error persists contact customer service at [email protected]. |
06 | The vehicle exceeded the allowed charging current. | Turn off the charger from the main switch, and turn it right back on. If the error persists contact customer service at [email protected]. |
07 | The charger detected a short circuit in the cable. | The cable may be defective. Restart the charger from the main switch and if the error persists, try using another cable for charging. |
08 | The temperature is too high. | Allow the charger to cool down and try again. If the ambient temperature is too high, try to cool down the environment. |
9 | An error occurred while locking or unlocking the charging cable. | Make sure the charging cable is not too stretched or strained Push the plug deeper into the socket and try again. If the error reoccurs then replace the charging cable with a new one. |
10 | A fault in the charging contactor applied the system protection device RCD | Turn on the RCD protection device. If the error persists, contact customer service. |
11 | There is no connection between the energy consumption meter and the charging station. | Contact the manufacturer at [email protected] |
Three status codes people ask about most
These are status codes, not manual codes, so they come from the list linked above. They turn up in support conversations often enough to be worth repeating here.
16 — "Voltage too low L1". The supply voltage on phase 1 has dropped below the level the charger will work at, and charging stops for as long as the code is active — it is not a warning you can ignore. Check that every fuse and breaker feeding the charger is on. If they are, the voltage itself is the problem: have an electrician measure it at the charger, and if the grid is the cause, your network operator has to fix it. The same fault on phase 2 or 3 appears as code 17 or 18 and is only a warning.
199 — "Power measurement system error". This used to show up as an unknown error and it is now a defined code: the charger's check on power-loss detection did not give a plausible result after charging started. It is a warning, it does not stop charging, and it clears itself about five minutes later. If charging did actually stop, something else caused it — send us the other codes.
155, older software 305 — "Invalid CP signal voltage warning". A warning from the checks that watch the CP wire in the Type 2 connector — the line the car and the charger use to negotiate. The CP codes were renumbered out of the 300s and into the 150s, so the same fault reads as 155 on a current charger and as 305 on one running older software. It is a warning either way, and when it shows up alongside a low-voltage code you should deal with the voltage first — that is almost always the real fault.
