Candy washer/dryer tripped electrics when start was pressed, traced to motor

The problem

A Candy washer/dryer tripped the household electrics as soon as Start was pressed. The fault was narrowed down to the motor because the machine would operate without tripping when the brush connection was disconnected, but tripped again when the brushes were reconnected.

Likely cause

The accepted diagnosis was an insulation fault in the motor, with the armature or field coil likely leaking to earth. A build-up of carbon dust inside the motor was also given as a possible cause.

What fixed it

The recommended action was that proper diagnosis required an insulation test meter. As a practical attempt, the motor could be blown out to remove any carbon dust. The original poster then removed the motor, blew it out with an airline, and reported that after refitting it the machine no longer tripped at that stage.

• Motor was identified as the area linked to the trip
• Machine worked without tripping when the brushes were disconnected
• Machine tripped again when the brushes were reconnected
• Motor was taken apart and blown out with an airline
• After refitting, the machine no longer tripped on initial test
