I have an Indesit W101 washer that has developed a strange fault: when starting a wash cyle the machine starts to fill with water normally, then after about 30 seconds the pump runs continuously and the programmer clicks round and won't stop, even when it gets to one of the red dots where a cycle normally ends. The fault is intermittent, it started off happening once in about ten washes, but now I would say it is more like one in every two. If I switch the washer off on the power button, the fault resumes when I turn it back on. If I pull the plug out and leave it for about 10 seconds I can sometimes make it work ok if I try again, other times I have to repeat the process two or three times before it will accept the programme and work normally. I can tell if it won't work because the problem always starts after about 30 seconds, if it works for longer than that then it will be OK and do it's cycle normally. Has anybody seen this fault before & got any ideas?
Thanks in advance, Chris.
