Zanussi ZWD14270W Starts for 5 sec’s then stops and flashes

I have a Zanussi ZED14270w which is just over two years old. Recently it has been a bit tempermental, you select the programme you want, press start, then a sound clicks (door locking) motor starts like it warming up, then about 5 seconds later it clicks and stops and the timer starts flashing. It did this a few times and then it often decided to start working again… However for the last few days it hasn’t wanted to work at all on any programme.

If anyone has any ideas I would be very grateful, as i don’t want to replace the machine if it is something that can be easily fixed.
