INDESIT WG113D is leaking Water on fill at start of cycle at the rear of the Drum, looks like it could be coming from the Tension loop where a single bolt with a large Torx type head is securing it, no sign of any locking nut - so could this have come loose over time, not sure what the tension loop is and also not sure if there could be some sort of seal behind the rear of the drum that could have perished causing the leak. Any advice much appreciated, i would rather not replace the machine if this is a simple leak to sort out.
