Indesit WIXE127 washing machine - doesn't end wash cycle ater spin?

I have an Indesit WIXE127 washing machine that gets to the end of its wash cycle, spins, and then sits there showing "0:01" time left, filling and emptying water. The only way around this has been to either manually switch it off straight after the spin, or at some point afterwards, manually set it to the spin cycle which completes OK.

Has anybody had this problem? Ideas what's wrong?
Thanks!
