Product review (1 stars): Miele admits that these tabs can cause your dishwasher to oversuds and leak
I used these tabs after they were recommended to me by Miele Customer Service. Our dishwasher kept leaking, and Miele said it was from oversudsing. First they told me to use powder detergent instead of liquid, so I did. We kept getting the F70 error and leaks. Then they told me to use less powder. I was using only a tiny bit -- maybe a 1/4 teaspoon -- but I started using less. The dishwasher still leaked and returned the F70 error. I called again. This time, the customer service guy (who was genuinely helpful) gave me a multi-step process to clean any soap out of the dishwasher and recommended these tabs. I diligently cleaned out the dishwasher every 4-6 weeks, a process that took about 30-45 min each time. I also switched to the tabs. The leaking and error message still happened, albeit less frequently.

So that's a point in the favor of the tabs: they cause your dishwasher to leak slightly less than it did before and they also clean the dishes pretty well.

But when I finally got fed up (again) with the leaking dishwasher, I called a non-Miele tech, who called Miele as soon as he showed up to my house. Their assessment? I should be using half a tab because a whole tab is causing the oversudsing.

So, just to be clear, a Miele technical support employee -- not just customer service -- admitted that Miele detergent tabs can cause oversudsing when used as directed.

This is why this product gets 1 star. It can harm your machine, which can then cause permanent damage (and significant mold/mildew problems) to your kitchen floor or cabinets.
