Do not attempt to remedy this yourself this could be quite dangerous do not attempt or take any advice on fixing this problem yourself call a qualified engineer. This problem could be due to the motor itself either the motor is shorting out which could be down to the fact that it needs new brushes or the motor may need replacing itself. Contact an appliance engineer or if it is still under warantee call the supplier you purchased the machine from.
