First things first, check the fluff filter, since it is no doubt blocked. You can find this on the front of the machine lower Right hand corner, behind the flap. Expect a fair amount of water to come out, then pull out the fluff filter and clean it under a cold tap.
Unfortunately, mine has lost the plot. The filter is clean and there are no kinks in the pipe, but it is still not switching cycles, it basically can't drain itself.
I am currently using some drain unbloker down the sink to see if this eleviates the problem. Failing that I am going to have to call an Zanussi bod out to look at it, which will no doubt cost a fortune :( Only had the machine 18 months............
Thanks,
John.
