Fixing damaged PCB of ERSA MULTI-TC soldering iron

[K]

So I got myself a non-working ERSA MULTI-TC soldering iron, as a freebie along  some purchase, and a couple of nice tips for it.

As I had used this type of iron before and quite liked it, at first I thought just to buy the replacement controller PCB and simply replace it - the board was listed as available on ersa-shop.com. But, alas, it turned out that it is not intended for purchase, and I was informed that the iron should be sent to ERSA for repairs. This is still an option, but at first I wanted to understand how feasible is it to repair it myself.

As far as I can tell the previous owner decided to change the power cord and in the process somehow damaged the controller PCB - the temperature control pot is squashed into pancake and also probably did other damage trying to fix it afterwards. The remains of the poor pot and knobs were just stuck into the handle. The PCB did not smell funny, so for now I assume the magic some is still in.

The PCB itself was somewhat covered in flux, all I did was gently wash it with some acetone before taking the pictures.

I have sourced what looks like a compatible pot (PIHER, 6mm, 5k), however upon inspecting the PCB discovered that it looks somewhat bad:
- one broken trace and a maybe be a missing SMD component on one side (Picture "ERSA MULTI-TC Top"),
- a broken trace without clear indication from where to where it was going on the other side (Picture "ERSA MULTI-TC Bottom").

As far as I can tell there are no pictures or schematic of this PCB anywhere on the internet, so I need some help:
- Is there anyone with ERSA MULTI-TC, willing to open it up and check for the traces and that SMD component and its value?
- And maybe poke multimeter around the legs of pot, to see which ones are tied together?
- Any other suggestions on how to repair it? Or should I just send it to ERSA and be done with it?

Thanks!
