Before we move on to the troubleshooting methods, it’s suggested to check the settings. For example, if the dishwasher doesn’t drain when the cycle is completed, make sure that you’ve selected “at the end cycle” on the dishwasher, and it will drain out the water as soon as the cycle completes.

When people get a new appliance, they forget to check the manual in their excitement to use it. But a manual can include a lot of useful information. It can tell you how to set up your appliance and teach you how to handle common dishwasher problems.

Without reading the manual, you wouldn’t know which settings to select on your dishwasher to make it drain itself at the end of each cycle. So, it is best to read the manual that came with your KitchenAid dishwasher before you run into any problem.

First of all, if a bit of water is inside the filter area, it’s completely normal. So, if you are noticing this water around the filter area during cleaning, it’s fine since it moisturizes the seals. It will be automatically drained with the initiation of the next cycle.

If you are using a dishwasher for the first time, you may think that the water in the filter area is a sign of a draining problem. But a little water in the filter area is not indicative of a problem, so there’s no need to worry.

3. Knockout Plug

If you’ve connected the dishwasher to the disposer, you need to ensure that the knockout plug isn’t there. This is because when you add the knockout plug to the disposer inlet, the water won’t drain out. You can learn about how to remove and insert the knockout plug through the instruction manual.

Forgetting to remove the knockout plug is very common among users. Humans make mistakes quite often, and as a result, they run into problems. But if you made this mistake, there is no need to feel bad about it because you can fix it in a minute.

4. Disposer

Well, the function of this equipment is self-explanatory, right? With this being said, if the drainpipe or disposer has been clogged, it won’t let the water drain out. In this case, you need to run the disposer empty, and it will fix the obstructions and food in the pipe for optimal draining.

It is important to make sure that there are no food items on your dishes before putting them in the dishwasher. Over time, tiny grains of rice and other food items can gather in the pipe and obstruct the path of water.

If this happens, your dishwasher will not be able to complete the draining function. So, it is best to clean everything off of your plates before putting them in your KitchenAid dishwasher.

5. Doors

If you are using the dishwasher and the door is open during the cycle, it’s going to flash up the start or resume indicator light. If this is the case, you need to close the dishwasher door and press the start button.

However, you need to press the start button first and then close the door (make sure to close the door within five seconds of pressing the button).

The dishwasher won’t drain the water if the door remains open or gets opened during the wash cycle. You will have to start the wash cycle again for the dishwasher to drain the water.
