Kenmore Dishwasher takes too long
If your Kenmore dishwasher takes too long, the problem is often tied to weak water movement that also leaves the dishwasher not cleaning dishes the way it should. The most likely cause is a damaged wash impeller, which can’t push enough water through the wash arms, and on some models that means replacing the impeller alone while others need a full pump and motor assembly. Next, check the filter assembly, filter, screen filter, and strainer in the sump. If any of these are clogged with food debris, water flow drops, wash performance suffers, and the dishwasher cycle too long complaint becomes more common. A failing circulation pump is another common cause, especially if the motor is silent or only makes a humming noise after the unit fills. In that case, inspect the pump housing for debris and confirm power is reaching the motor before replacing the pump. If your Kenmore dishwasher runs for hours or is not washing properly, enter your model number on RepairClinic.com to find the exact wash impeller, circulation pump, filter, screen filter, strainer, or pump and motor assembly that fits your specific dishwasher.
01 - Kenmore Dishwasher Wash Impeller
The wash impeller is a small plastic blade that forces water up through the wash arms. If the impeller is broken or is missing some of its fins, it might not generate enough pressure to force the water up through the wash arms. 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.

02 - Kenmore Dishwasher Filter Assembly
A dishwasher's filter assembly usually consists of both a course and a fine filter located in the sump. If one or both of these filters is clogged, you will get low water flow and poor washability. If the filters cannot be cleaned effectively or if they are damaged, they will need to be replaced.
Highly Likely
03 - Kenmore Dishwasher Filter
A dishwasher's filter assembly usually consists of both a course and a fine filter located in the sump. If one or both of these filters is clogged, you will get low water flow and poor washability. If the filters cannot be cleaned effectively or if they are damaged, they will need to be replaced.

Highly Likely
05 - Kenmore Dishwasher Strainer
Dishwashers will use a strainer located in the sump to catch food particles. If the strainer is clogged, you will get low water flow and poor washability. If the stainer cannot be cleaned effectively or is damaged, it will need to be replaced.
Highly Likely
06 - Kenmore Dishwasher Circulation Pump
The circulation pump uses a motor and impeller to force water up through the wash arms. If the circulation pump is defective, the dishes won’t be cleaned properly. If the motor isn’t making any noise or is just making a humming sound after the dishwasher has filled, the motor may be burned out. First, ensure that power is getting to the motor. Second, to ensure that the impeller can turn, check the pump housing for debris. If power is getting to the motor and the pump is clear of debris, the motor might need to be replaced. Be aware that the circulation pump may be challenging to replace, although many do-it-yourselfers ha...
