Try resetting the machine:
- Press the first and third button together for 2 seconds. It will display "0" then take about a minute to shut down.
- Switch the machine off for a few minutes.
- Switch it on again and it should work.
Otherwise, refer to:

The reset appeared to fix mine, although this was hampered by the fact my 'economy' button is temperamental!
Hope this helps.
