You need to unplug the appliance, take the top and side panel off.
You should be able to see the cable entering and it should have a suppressor it attaches to.
This is the likely part that has blown.
Check it out, see what you find and get back to me.
Also, let me know the E-Nr number of the appliance so I can have a look at the diagrams.
I'll be out at work during the day but I'll pick up again when I get home.
The top is normally clips that you push up so the lid slides rearward.
The screws are normally down the front edge.
I still need the E-Nr number.
