Flashing lights on Hoover Vision HD ?

Hi,
I have a Hoover Vision HD 1400 8Kg Washing Machine that will not complete it's cylce.
Everything starts ok but about half way through it stops and the time saver & 1200 spin speed lights flash 3 times then a gap of about 5 seconds then flash again, and so on.

I have had this fault before but it was repaired under warrenty and they didn't say what the problem was ( i wasn't there at the time).
Anyone got any ideas before i start pulling it apart.
Thanks in advance,

Steve.
