Thanks for replies,I will try an 03 and see what happens.
Simon,this is not my main machine,I use a Prochem Steempro,and have done so for many years

We purchased this baby machine with the idea of using it in hard to access bedsits etc,you know the ones up several flights of stairs,round the corner and keep going and then you find a room the size of a shoebox

It would never be powerful enough to clean a house full of carpet ,it would take a month of Sundays. -John
