Nayax “Cashless Out of Order” (M00 / V00 / V01)
If the Nayax terminal shows “Cashless Out of Order” with code M00, V00 or V01, it’s usually a lost link between the terminal and the machine over the MDB cable — not a failure of the Nayax unit itself.
What to check
- Restart only the payment terminal (without turning the machine off) — this often restores the link.
- Check the terminal’s MDB cable: is it seated firmly, and does the terminal have power?
- Confirm the machine has internet — for the terminal’s online functions.
- If the machine also has a water or brewing error, the terminal may fault along with it; fix the main problem first.
Terminal configuration (MDB connection) is on the Machine Settings for the NAYAX Terminal page — this page is about restoring the link, not the initial setup.
If the link won’t come back, send us the reader’s serial number and we’ll check on the Nayax side.
