Zanussi Dryer, no warning lights, won't start?

Hi I have a condensor dryer TCE 7276W

There are no red warning lights on and all three green lights are on and steady for Drying, Cooling and End with the dial selected to a programme, off when programme not selected.

With a programme selected the display correctly displays the expected time and the green light for Start/Pause is flashing.

When the orange start button is pressed nothing happens! No motor sound, clicks or anything. Any ideas please?
