I have a indesit WG924 Washing Machine. Today I did a wash and when the timer gets to the cycle that drains the water, the machine stops and does nothing. You can hear the timer clicking but does nothing. The timer sound louder than usual also (may be because I had cover off machine. Even if I move the timer by hand the machine will still not drain. Please can somebody advise what this could be and how to replace the faulty part.
