Boa tarde alguem me sabe dizer na maquina da Whirpool ADP4542 o que quer dizer a luz acender 7 vezes?

Em principio é isto:

F7 error fault code
This is flow meter failure. The flow meter impulse wheel (situated in the water tank) is not turning correctly, too fast or too slow
therefore the electronic impulses received by the module/pcb are not correct, also the water valve can be faulty.
