Indesit Washer/Dryer Not Heating

Hi

I have just moved into a house and the dryer doesn’t appear to be working on the Indesit WDG1195W that is installed it turns but is not drying clothes or getting warm. Apparently it has a ‘self cleaning’ filter and I can’t see one in an obvious place being a novice and pretty much clueless with washing machines etc one odd thing I notice is the power light above the on and off switch intermittently flickers on and off it’s sporadic more like a bad earth/ground somewhere. I popped the lid off and found this:

First of all whoever had been in this last had done a really bad job with cutting the main power wire off to wire it up to the mains as there was straggles of wire hanging out of it. But also noticed these two plugs taped up.. (on closer inspection was this mains lead supposed to attatch
to something on top of the heater element that is no longer there?)

Cut mains wire:

One with brown and black wire:

and one with two brown wires:

The only spare terminals I can see where they could/should? be attatched to is here: which I am guessing is the heating element.

and possibly on the selector dial here

(that last one is probably an unlikely guess but since I know nothing about these. Or why indeed the previous occupier or whoever decided to unplug these I’m finding it difficult to suss out. Any ideas where these two plugs should attach to or any other ideas?
