Jenn Air Dishwasher making noise
If your Jenn Air dishwasher is making noise, start with the parts most likely to cause it. A dishwasher making noise often points first to a drain pump clogged with debris or a drain pump that is wearing out. Next, check the circulation pump, since worn motor bearings can create a steady drone while the dishwasher runs. A damaged drain impeller can also cause a dishwasher loud noise by struggling to push water through the drain hose, and a worn pump and motor assembly may be the source if the motor bearings, drain impeller, or wash impeller are failing together. The wash impeller itself is another common cause of dishwasher grinding noise if the blades are broken, warped, or scraping the pump housing. On some Jenn Air models, the circulation and drain pump motor can also produce a humming or droning sound when the bearings fail. Enter your model number on RepairClinic.com to find the exact Jenn Air replacement part for your specific dishwasher, whether you need a drain pump, circulation pump, drain impeller, wash impeller, or complete pump and motor assembly.

02 - Jenn Air Dishwasher Circulation Pump
The circulation pump motor has bearings that wear out over time. When the motor bearings fail, they generate a continuous drone. If the motor bearings have failed, you must replace the entire circulation pump.

03 - Jenn Air Dishwasher Drain Impeller
The drain impeller pushes water through the drain hose and into the garbage disposer or drain line. If the impeller is broken, replace it.

04 - Jenn Air Dishwasher Pump and Motor Assembly
Part of the pump and motor assembly (such as the motor bearings, drain impeller, or wash impeller) might be defective. Often, you can replace the pump’s individual parts. However, if you do not want to disassemble the pump to replace its parts, or if the parts are not available separately, you can replace the entire pump and motor assembly.

05 - Jenn Air Dishwasher Wash Impeller
The wash impeller is a small plastic blade that forces water through the spray arms. If one or more of the impeller blades is broken, the dishwasher will make noise. In addition, if the impeller is damaged, warped, or bent, it can scape against the pump housing. Inspect the wash impeller for damage. If the wash impeller is damaged, replace it. On most models, you can replace the wash impeller independently of the pump and motor assembly. Search for your model number to determine if your impeller is replaceable. If the impeller cannot be replaced separately, you will have to replace the entire pump and motor assembly.

06 - Jenn Air Dishwasher Circulation and Drain Pump Motor
The circulation pump motor has bearings that wear out over time. When the motor bearings fail, they generate a continuous drone. If the motor bearings have failed, replace the motor or replace the entire pump and motor assembly.
