I took apart the supply and eventually found this mysterious part. It has clearly been very hot at some point and is all cracked to pieces. It has been very warm at some point in time Here is its cremated remains. Looks to have been about 8mm in diameter and about 7mm long with the connections at the round ends. And this is the board serial number I have no schematics for this supply so i can not look it up what i could be. I know where to find a couple other similar machines so one possibility is that i go and take apart another one and check what it is. Maybe i could even borrow a supply.
I am just suspicious of what caused that part to fail. And if it could have damaged anything else in the process. At a glance everything else looks fine at least, with no obvious signs of heat or burning
Same component was aslo burnt to a crisp and it already looked to have been opened up and fixed once at some point. The pcb even had a hole burned thought the board under the component. My board is luckily only a bit burnt. So still no luck in identifying what the toasty little component used to be
