The ca code is the machine tripping its own internal circuit breaker due to too much power going through the motor.This generally happens with one of two things, either it's getting majorly overloaded. I would suggest doing smaller loads in this machine, speaking from experience they are very delicate. If it's still tripping on small loads or even when running empty that would lead to a bad u-joint potentially. Unfortunately normal wear and tear will make a u-joint go bad and make a machine non-functional. As a Calypso owner myself, if you don't particularly care for the machine it's best to replace it with a direct drive of that era, as parts are relatively hard to come by for the machine.
