Did the burning smell start as soon as you switched on or did the machine start to fill? Normaly burning smells come from either the main motor, the pump,or associated wiring (rarely from the heater) that just blows the fuse. The best thing I can suggest is to turn the appliance OFF and sniff the motor and pump...You will know if they are the cause by the smell or check for any worn or loose wires that may have come in contact with the cabinet. The best way to test is with a multi meter and the machine disconnected from the main power supply. Good Hunting!
