Water-cooled MOSFETs! I've heard these machines have various problems, but you have to respect the innovation that these engineers have shown.
I don't need to fix this one :-)... but I'd like to hear from anyone who's successfully hacked the module to use it for another purpose... It looks like a dual H-bridge driving a whopping stepper motor direct from the rectified mains... is my guess right? That motor must have huge torque to agitate the wash load.
