a). Should this worry me ?
b). Will it be a costly fix ?
Get a voltage meter and start touching touching the machine with both probes in different locations to track down the area at risk. Mine was with the lamp , the previous owner had used foil to tighten up the light bulb. Removed the foil and problem was solved.
