Hello

You need to check the amperage draw of the motor,The only possibility is a shorted winding in the motor, or a bad motor.

Also check for correct voltage to the motor after the fusible links.Make sure the links are the correct size also.

Voltage and FLA or full load amps should be marked on the motor.You need to be within 5 to 10 percent of that number.

There is a problem in the heating element. The element is short circuit. Please check the heating element. See if water or any conducting thing is shorting the element. This will solve the problem
