This is the replacement impeller kit for your dishwasher. This impeller kit comes with 4 pieces, including the impeller and seals which you will need for the repair. The impeller and seal kit is mounted on the dishwasher motor. If your dishwasher is not cleaning dishes properly, it may be an indication that your impeller has gone bad, and you are not getting proper water pressure. If the seals have gone bad, your dishwasher may start to leak. If you are having either of these problems, you may need to replace the impeller kit. Be sure to disconnect the water and power source from the dishwasher before you begin this repair. This is an OEM part sourced directly from the manufacturer.
