Whirlpool Dishwasher making noise
If your Whirlpool dishwasher is making noise, start with the parts most likely to cause it. A Whirlpool dishwasher loud noise or dishwasher grinding noise is most often traced to the drain pump, especially if debris is caught inside or the pump is worn out. Next, check the circulation pump, since failing motor bearings can cause a steady dishwasher humming noise or drone during the wash cycle. A broken drain impeller is another common cause, followed by problems in the pump and motor assembly, where worn bearings, a damaged drain impeller, or a faulty wash impeller can all create noise. The wash impeller itself can also cause a dishwasher making noise complaint if its blades are broken, bent, or scraping the pump housing. On some Whirlpool models, the circulation and drain pump motor can develop bad bearings and produce the same symptom. If your dishwasher buzzes, drones, or makes grinding sounds, inspect these parts in order and replace the failed component. Enter your model number on RepairClinic.com to find the exact Whirlpool drain pump, circulation pump, drain impeller, wash impeller, or pump and motor assembly for your specific dishwasher.

02 - Whirlpool 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 - Whirlpool 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 - Whirlpool 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 - Whirlpool 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 - Whirlpool Dishwasher Circulation and Drain Pump Motor
