Wi-Fi and Cookidoo®: connection not working

The Thermomix® can’t find the Wi-Fi, the password isn’t accepted or Cookidoo® reports another account? The fixes for the TM6 and TM5.

For the TM5 and TM6 · Mixklinik workshop · Updated November 2026

In short

Restarting the router, switching the Thermomix® Wi-Fi off and on again and checking the password carefully solves most cases. Networks with a login page, as in hotels or offices, don’t work. A second-hand machine must be disconnected from the previous owner’s Cookidoo® account.

TM6: built-in Wi-Fi

  1. Restart the router and wait until it’s back online.
  2. On the TM6, switch Wi-Fi off and on, restart the machine and select your network again.
  3. Check the password with “Show password”. Some special characters aren’t supported.
  4. If that doesn’t work, try connecting to another network. Phone hotspots and restricted networks often cause problems.
  5. As a last step: Menu, Settings, Factory settings.

Bought a second-hand machine? If the TM6 is still linked to the previous owner’s Cookidoo® account, you can’t use it with your own account. Ask the previous owner to disconnect it. If that doesn’t work, Vorwerk customer service can help.

TM5: Wi-Fi via the Cook-Key®

The TM5 has no built-in Wi-Fi. It connects through the Cook-Key®, which attaches to the side. According to Vorwerk it needs a 2.4 GHz network (802.11 b/g/n) with WEP, WPA or WPA2-Personal. The Cook-Key® must be activated in your Cookidoo® account.

  • Remove the Cook-Key®, reattach it and restart the TM5.
  • Reset the Cook-Key® to factory settings without removing it during the reset.
  • Only remove the Cook-Key® using “Eject Cook-Key” in the settings, otherwise it can be damaged (C811).
  • Avoid 2.4 GHz interference such as microwaves or baby monitors and keep the machine within range of the router.

You’ll find the individual codes in the error code list. If the Cook-Key® still reports C800 or C563 after all that, it needs replacing.
