Hotpoint Dishwasher making noise
If your Hotpoint dishwasher is making noise, start with the most common culprit: the drain pump. A dishwasher making noise can happen when the drain pump is clogged with debris, and if it is clear but still loud, the pump likely needs to be replaced. Next, check the circulation pump, since worn motor bearings often cause a steady droning or humming noise. After that, inspect the drain impeller, which pushes water through the drain hose, because a cracked or broken impeller can create extra noise during draining. The pump and motor assembly is another likely source if internal parts like the motor bearings, drain impeller, or wash impeller are failing. A damaged wash impeller can also scrape the pump housing and cause a grinding noise or buzzing noise while the spray arms are running. On some Hotpoint models, the circulation and drain pump motor itself may be the problem if the bearings are worn out.

02 - Hotpoint 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.

04 - Hotpoint 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 - Hotpoint 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.

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.
