mode of operation
The way in which something, for example a machine, a system, or a process, works.
Können Sie mir bitte die Funktionsweise dieses Geräts erklären?
Could you please explain the mode of operation of this device to me?
The word is made up of 'Funktion' (function), the linking 's', and 'Weise' (way). So it literally describes the 'Art und Weise der Funktion' (the way of functioning).
Die Funktionsweise des neuen Systems ist ziemlich komplex.
The mode of operation of the new system is quite complex.
To say what object's mode of operation is being described, you usually use the genitive or a 'von' construction. The genitive is more common in written language.
Ich verstehe die Funktionsweise des Geräts nicht.
I don't understand the mode of operation of the device.
Common verbs used with 'Funktionsweise' (mode of operation) are 'erklären' (to explain), 'verstehen' (to understand), 'beschreiben' (to describe), and 'kennen' (to know).
Der Techniker hat mir die Funktionsweise der Heizung erklärt.

function
'die Funktion' and 'die Funktionsweise' are closely related because both have to do with how something functions. 'Funktion' refers more to the task or purpose: What does something do? 'Funktionsweise' refers more to the manner or mode of operation: How exactly does something work? Learners may confuse the words because with devices and systems, people often talk about both. As a simple guide: when you are naming the purpose, use 'Funktion'. When you are explaining the process or mechanism, use 'Funktionsweise'.
