White-Westinghouse Dishwasher making noise
If your White-Westinghouse dishwasher is making noise, start with the parts most likely to cause it. A White-Westinghouse dishwasher loud noise or dishwasher grinding noise often comes from a drain pump that is clogged with debris or failing internally. If the drain pump is clear, the next common cause is the circulation pump or circulation and drain pump motor, where worn motor bearings can create a steady droning or humming sound. A broken drain impeller can also make the dishwasher making noise during drain cycles, while a damaged wash impeller can scrape the pump housing and cause grinding or rattling when the unit is washing. If the individual pump parts are worn and not sold separately for your model, the full pump and motor assembly may be the right fix. Checking these components in order gives you the fastest path to the problem, whether your dishwasher buzzing noise happens while draining or your dishwasher humming noise shows up through the whole cycle. Enter your model number on RepairClinic.com to find the exact White-Westinghouse replacement part that fits your specific dishwasher.

02 - White-Westinghouse 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 - White-Westinghouse 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 - White-Westinghouse 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 - White-Westinghouse 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 - White-Westinghouse 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.
