Amana Dishwasher making noise
If your Amana dishwasher is making noise, start with the parts most likely to cause it. The drain pump is the first thing to check, since debris caught in the pump can cause a dishwasher grinding noise or buzzing noise, and a worn pump can stay loud even after it is cleared. Next, look at the circulation pump, where failing motor bearings often create a steady drone or humming noise while the dishwasher is washing. A broken drain impeller can also make your Amana dishwasher loud by affecting how water moves through the drain hose, and a damaged wash impeller may scrape the pump housing and cause a sharper mechanical sound. If the individual pump parts are worn or damaged, the larger pump and motor assembly may be the real source of the problem, including the motor bearings, drain impeller, or wash impeller. On some models, the circulation and drain pump motor itself is the failed part. To find the exact replacement part for your specific dishwasher, enter your model number on RepairClinic.com and match your machine with the right Amana drain pump, circulation pump, impeller, or pump and motor assembly.

02 - Amana 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 - Amana 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 - Amana 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 - Amana 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 - Amana 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.
