Kenmore Dishwasher making noise
If your Kenmore dishwasher is making noise, start with the parts most likely to cause a buzz, drone, or grinding sound. The first thing to check is the drain pump, since debris caught in the pump can make a Kenmore dishwasher loud, and a worn pump will stay noisy even after it is cleaned. Next, look at the circulation pump, where failing motor bearings often create a steady droning noise during the wash cycle. A damaged drain impeller is another common cause, followed by problems in the pump and motor assembly, including worn bearings, a bad drain impeller, or a bad wash impeller. The wash impeller itself can also cause dishwasher grinding noise if the blades are broken, bent, or scraping the pump housing. On some models, the circulation and drain pump motor can be replaced separately, but in other cases you will need the complete pump and motor assembly. If your dishwasher making noise issue points to one of these parts, enter your model number on RepairClinic.com to find the exact Kenmore replacement part that fits your dishwasher.

02 - Kenmore 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 - Kenmore 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 - Kenmore 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 - Kenmore 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 - Kenmore 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.
