I have a Fisher and Paykel Washing Machine (model number WL80T65C, well past warranty) which got rained on (a lot) and one of the capacitors blew up. I've done an amateur replacement of the capacitor which might work but when taking the circuit apart I forgot to take a photo until half way through. I've managed to place everything except for two cables, one of which is Green/Yellow and coming from the mains. This is Australia so I presume it's a ground cable.
The only hint I can find as to which is the ground and which is the other is the sad face that's printed on the circuit board, as shown in the photo attached.
The cables connect to where the blue marks are, one on the left and one on the right.
So, is a frown face in a PCB a standard thing and does it tell me which is ground or are Fisher and Paykel mocking me? Is there a place where I can look for the schematics of this thing?
Edit: Here's a better photo of the sad face and its friend, taken in the day time.
NB: It's become apparent that the component was ground and it didn't matter which way around I fixed the cables but I'm still curious as to what the sad face means.
