Dishwasher Not Cleaning

If your Dishwasher is not Cleaning the Dishes check the following

No water Entering Dishwasher

Check to make sure water is entering the dishwasher do this by starting a wash cycle wait for it to fill and start washing then open door. If there is no water you will need to check the water inlet valve and the float switch. This video will walk you through checking both out.

Low Water level

This is another common problem. To check that you have the proper water level you will need to turn dishwasher to a wash cycle wait for it to fill, when it starts washing stop and open the door. Now refer to the tech sheet or service manual for the proper water leve. They usually refer to a fixed point in the dishwasher or to a specific measurement. This ensures that your dishwasher has enough water to wassh properly. If your water level is low you will need to check the water inlet valve and the float switch. The video will walk you thru inspecting and testing these components. The links will lead you thru a photo tutorial on replacing these parts.

Wash Arms

First check to see if they are moving. To do this start dishwasher into a wash cycle wait for it to fill and start washing open door and rotate wash arms to a certain position remeber this position then close the door let run for a few seconds and open door. If they are not moving check to see if they turn freely if not replace. Next remove the spray arms and check for clogged holes. If all looks clear you will need to check that the circulating pump is not clogged up or has failed.

Drain Problem

This is one of the most common reasons. To check open door after a cycle and check to see if any water is standing inside. If there is you have a drain issue. Could be the high loop or air gap is not correct. The drain may have a clog. The drain pump may have failed. The drain pump can be checked for the proper ohm reading (refer to tech sheet). If it is out of specification replace the pump. Check to see if the drain pump is getting power. If the drain pump is getting power but not running you will need to replace. If it is running but still leaving water behind you will need to remove the drain pump and check/replace for obstructions.

Control

This is the least likely cause.Check to make sure it goes to each cycle for the proper amount of time. The main control or Timer has a pre determined amount of time programmed into it. This determines how much time to spend at each cycle. The time is usually printed on the tech sheet. The tech sheet is located somewhere on your dishwasher. It could be behind the front panel,behind the console, behind the toe kick, somewhere on the sides. If it does not stay at each cycle for the proper lenght of time you will need to replace the control.
