How can I repair my Flymo Lawnmower?

Dear Sir,
I own a " Flymo " Lawn mower.
Product No. 9643201-01
Serial No. 01903571
Model.VT 320. 230V, 50Hz, 1.0kw., 32cm.

The problem is, when I depress the starter switch, there is a slight noise burring sound at the switch, but the blades do not rotate.
Could you tell me the problem, and what can I do to repair it?
I live in Kuala Lumpur , Malaysia. I bought the Flymo in England, some 4 years ago.

I am willing to buy spares from UK if it needs to be. I really aqm attached to this mower, and do not want to loose it.
Could anyone Help, please!!!!!!

Thank You in Advance,

Kandi Subramaniam
