the 6 code is the under pan of the foot plate.
it is known problem with the minivator models and the connection has more than likely come away from the switch.
it is only a 5 min job to remove the plate, solder the switch, extend cable and then re-apply the footplate.
dont let anyone charge you any more than around £100 - £120 for the callout and repaair as this is what we would charge.
if you dont want to pay this you can allways bypass the switch but its not really safe...
