This Electrolux model was only sold for the year 1997/8 I believe...
If the fault is intermittent cutting out then it may be the cord at the plug-end - cut the plug away with about 6" of cable and fit a new plug.
A very common fault on ALL vacuum cleaners is a broken wire inside the cable - from constant tugging - the wires stretch and one of them eventually breaks.
