Der Sir;
The power switch is failure , you must Change the switch. You must be shure the some wires is Not loose, otherwise the wires will be touching the carcase causing the spark inside. Retight the wires or solder .You must inspect the main motor board and all the element around . If someone is burned or other wires is touching the carcasing producing the spaprk.
sincerely. God bless you.
