I had a problem with my machine after some years - the electronic controller has a circuit board, with another soldered to it. At the point when the machine failed altogether, 6 joints had broken! The repair required a drop of solder on each of the broken joints. I forget when I did this - which suggests a couple of years ago or more - has been perfect ever since!
The quality of manufacture of the circuit boards was very good - just not really suited to the vibration of a washing machine!
Please note, I'm not a professional washing machine repairer, so do not ask me to carry out repairs like this - if necessary, buy a soldering iron and some solder, and learn to solder - it's a skill that will serve you well!
