Kenmore Dishwasher Not Washing: Potential Causes and Solutions

If the water inlet valve is not working properly, it can cause the dishwasher to not wash properly.
Why does it fail?
There are many reasons why the water inlet valve may fail. The most common reason is a build-up of mineral deposits. Over time, these deposits can build up and cause the valve to not work properly.
Another reason for failure is a bad seal. If the seal on the valve is damaged, it can cause water to leak into the dishwasher.
How to fix it:
If the water inlet valve is not working properly, you will need to replace it. You can purchase a new water inlet valve at most hardware stores or online. Be sure to follow the instructions that come with the new valve.
To replace the water inlet valve:
-Shut off the water to the dishwasher.

-Do not use harsh chemicals or cleaners on the dishwasher.
6. Wash Impeller
What is it?
The wash impeller is a plastic device with “blades” that sits at the bottom of your dishwasher’s tub. Its job is to spin and force water through the holes in the spray arm, thereby washing your dishes.
If it’s broken: You’ll know if the wash impeller is broken if your dishwasher doesn’t seem to be washing the dishes as well as it used to. There may also be water leaking from the bottom of the dishwasher.

Remove any food or debris that gets caught in the blades and make sure nothing is blocking the holes in the spray arm.
If you notice your dishwasher isn’t washing as well as usual, check the impeller to see if it needs to be cleaned or replaced.

You should clean your filter every month or two, depending on how often you use your dishwasher. To clean it, simply remove it and rinse it off with water. You can also brush it with a soft bristled brush to remove any stubborn dirt or debris.
Why is it important?
A clean filter is important because it helps to ensure that your dishes are getting clean. If your filter is clogged, it can prevent water from flowing properly and cause your dishes to come out dirty.
