The top rinse sprayer(plastic propellor) has fallen off but I can't find any missing or broken parts in the bottom of the dishwasher or in any of the plates, cups etc. What if anything do I need to purchase? I can't find a model number on the dishwasher, I just know that it's a Simpson Contessa.
The receipt from my last repair said that it is a 52B682.
