AWSL lathe power fault

Hi got the above machine recently

It’s the variable speed version

It was running fine but now when i turn the power on,the motor doesnt turn

The power comes on

The speed indicator on the pulley housing lights up ,and when you turn the wheel by hand it registers a speed

When I turn the speed knob,the motor doesnt come on to turn

There appears power to the control box and the motor housing

Im hoping it’s a minor item that is faulty etc

Any advice/hints would be welcome

Thanks Bruce
