A:Answer Hello- Thanks so much for your question. We are happy to help! The dishwasher will still run with a broker disposer, however if there is food inside the dishwasher, the dishes won't get properly cleaned. ~Our dishwashers have a an anti-jamming Piranha hard food disposer. The Piranha food disposer inside the dishwasher grinds food particles before they go down the drain. This clears the passage through to the drain and eliminates the need to pre-rinse dishes. The Piranha hard food disposer is made of stainless steel and will never rust. The motor has a small stainless steel blade on the motor that chops up food before it passes through the pump screen and into the pump area. This blade spins at 3200 revolutions per minute. The motor pumps 35 gallons of water per minute past the food disposer, through the pump, and back into the tub. If you have any questions in the future, please let us know. We are here to help!
