There usually are silver points in relays and switches.
Older ones have a mecanical program switch with silver points (a box with a lot of wires connected and a small motor), in newer units the mecanical switches are replaced by a pcb. If there is a knob on the front to select washing program you could be in luck, but if there is buttons and a display it is a newer one and built around a pcb.
The most value is probably in the base metals, stainless steel, copper wiring in cables and the motor, aluminum, iron, brass.
In my youth 30 years ago I was hunting for silver on the city dump. I found some washing machines which contained relatively much silver in the program switch and it was easy to get it loose. I still have my silver collection in a box and I'm going to run it in a silver cell when I get some time and space to build one. My goal was to make a 1 kg silver bar from contact points. I think I have over two kilos in that box so it's about time to refine it now. :mrgreen:
