Visited an Indesit IWC71452 today, tried various functions and seemed ok, ran it through the test cycle and again all seemed ok.
Customer rang later on to say it stopped with start light amber and just the bottom LED on, which I believe is F01 (motor triac), just checking im reading the code correctly before going back.
Been back, this time it when testing it failed on the main wash valve so replaced that and has now completed cycles, guess they misread the code on the display.
