My Indesit W123S machine continuously fills with water throughout the whole cycle. I had a repair guy in who said he thought it was the pressure switch as it only clicked once when he blew into it. I replaced the switch but it still continuously fills. Should I now be thinking its the module or should I replace the valves at the back? I get 3 flashes for an error code but can't find an interpretation of this anywhere. The module was replace a few months ago while the machine was still under warranty - it's now 16 months old. Thanks
