2. Error 06 — Token Mismatch or Wrong Token
Error 06 appears when the meter does not recognize the token you’re trying to load. This could happen because of:
- Typing errors
- Tokens generated for another meter
- Used or invalid tokens
- Temporary vending glitches
How to Fix It
- Re-enter the token slowly
- Double-check every digit
- Request a fresh token if it still doesn’t work
- Always buy from trusted platforms like LightNG to avoid wrong tokens
3. Error 10 — Invalid Meter Number
This usually happens during purchase, not on the meter. The vending server struggles to identify your meter temporarily.
What to Do
- Confirm your meter number
- Wait a few minutes and retry
- Use platforms that notify you about DISCO downtime
4. Error 30 — Communication Failure Inside the Meter
Error 30 happens when your meter and keypad are unable to communicate.
How to Fix It
- Disconnect and reconnect the meter (only if safe and accessible)
- Check if the installation is loose
- Contact your DISCO if the issue persists
