Re: fisher paykel dd603
If the impellar comes away from the rest of the rotor motor then it is knackered, part number is 525884P
It is possible that the motor housing might be damaged, if it is badly scored inside you sometimes get a problem where the drawer won’t empty fast enough. So once you have the old rotor motor out take the other one from the top drawer and fit it to the bottom to see if it works. If the motor housing is gone you need part number 528042.
