Thermomix TM5 error c30. Does anyone know how to repair or reset the system? thanx
@jeeffi79 C30 is definitely one of the dumber error codes they could come up with. It is totally generic and “A repair is only required if the system message keeps reappearing.” Anyhow you could try a hard reset. Foir that you simply push and hold the Home Button for more than 3 seconds. For other resets you would have to have access to the menu “Menu” > “Settings” > “Factory Reset”. See what that does.
