2. Power disk needs to be installed (new dishwasher installs)
Many Miele dishwashers have what is called a Power disk. It’s a compartment that holds dishwashing powder. The amount of dishwashing powder in it will last about 20 washes.
On new Miele dishwashers the Power Disk is not installed, and you need to install it yourself. Check the Power Disk is installed using the instructions shown in the video below:
3. Power disk is empty
Another similar issue to the one above is the Power Disk is empty. Typically, there will be a message on the display that tells you when the Power Disk is getting low. As well as, when it needs to be replaced.
Inspect the Power Disk using the instructions in the video above to see if it’s empty. And if it is, how to replace it with a new one.
4. Fill channel was not reinstalled
There is also what is called a fill channel on Miele dishwashers. It can be removed and cleaned. And you typically need to do it each time you replace the Power Disk.
It does differ by model, and is easy to take in and out. Refer to the owners manual for your specific Miele dishwasher model to see how to check the fill channel is installed. An online version can be downloaded here from the official Miele dishwasher.
5. The spray arms are clogged and need to be cleaned
Virtually all dishwashers including Miele dishwashers have spray arms on the top and bottom of the dishwasher. They spray water on the dishes and clean them. The spray arms can develop clogs in the holes where the water sprays out.
If they are clogged then it will stop the spray arms from spraying water, which can cause an error code. Or, the dishes won’t be clean at the end of the cycle. To inspect and clean the power arms on your Miele dishwasher follow the instructions shown in the video below:
6. Rinse aid volume or water hardness are set incorrectly
Miele dishwashers have a Rinse aid setting and water hardness setting. If either of these are not set to the right levels, Miele says they can cause your Miele dishwasher to stop mid cycle. Refer to your owners manual to see how to adjust the settings for your specific Miele dishwasher.
You can download an online version of your Miele dishwasher on this page of the official Miele website. It requires you to put in your model number. On both freestanding and built-in dishwashers the model number is shown on a label that is on the right hand side of the door.

7. Air gap in drain hose (only if connected to garbage disposer)
If your kitchen has a garbage disposer then do this step. Otherwise, skip to the last step below. It’s common for the drain hose on a dishwasher to be connected to the garbage disposer.
As it drains the water goes down the same pipe that is connected to the garbage disposer. This part of the connection from your dishwasher to your waste water can develop a clog, or it can have an issue that prevents it from operating properly. The video below shows how to clean an air gap.
Air gaps are of a few different types. So, if you’re unsure how to unclog it, it’s best to contact a dishwasher repair person or a plumber.
