INDESIT WIL153?

Hi, just goes to show having codes doesnt always help, mine isnt showing a fault code but it wont work!
when you turn it on the solonoid valve opens for a second then shuts and the power light goes off, although the selected wash light stays on. It wont spin or pump out if you try selecting either of those options,i tried sucking on the pressure switch and all it would do is turn the pump on, and the drum doesnt turn at all.
does anyone have any ideas as to what is wrong?
many thanks in advance for any help offered.
