Technicians Advice

A machine that trips its overload the moment you pull the trigger, but runs happily in bypass, is not usually an electrical fault at all. It is the pump loading the motor because the unloader has stuck closed or the nozzle is blocked. Check the water side before you spend money on a contactor - and if the motor is drawing hard enough to trip an overload, stop using it until you know why, because that is how you cook a winding.
