This error may be due to a malfunctioning recipe chip/Cook-key®. In this situation a quick test is needed: remove the chip/key and use the TM5 without either/or attached. If the TM5 works without a chip, the recipe chip needs to be replaced. If the TM5 does not work correctly without a recipe chip, it is likely the Thermomix® needs repair; call Service at 855-867-9904 for next steps.
