That indicates that the heater relay on the module is stuck but it could still be the pressure switch, these washers are utter cr*p I'm sorry to say not just yours but the whole range of indesit/ariston I am sorry but I don't know what else to tell you as the fault now is on the module, it could be that changeing the heater relay (which are prone to going) would fix the fault but I think this would be beyond your scope.
