had the same problem.
went to remove the valve which is where the inlet hose is attached and found that the tray at the bottom had water in it? this tray has a switch and poly float, when the tray was drained the switch is reset and washer is now working ok.
if yours still does not work you can get the solenoid valve from www.indesit.co.uk
hope this helps
