the boiler is heating up but no steam, can it be fixed?

i bought a polti vapporetto 2300 and the boiler heats the water up but it does not emit any steam. Iv tried all the various rinsing out cooling down etc, but it still wont work. How can i fix it? or is there anyone in the Rotherham, South Yorks area that will be able to fix it for me- may i add, without the heavy price tag!! Many thanks. The Model is the 2300 vapporetto, model number VT2300 PTEU0149 and it is the blue rounded version bit like the look of a vax machine!
