If you're looking for how to manage the "Cleaning" notification, here's the TL;DR from the poorly written manual:
1) Go to page 7 for the descaler ratios in step 1. Fill tank with your descaler solution. IGNORE steps 2 - 7 in the "Removing Mineral Deposits" section.
2) Place empty brew basket in coffee maker and empty carafe on the hot plate.
3) Go to page 5 or 6 (depending on your model), look for Function selection "C" for instructions on how to engage "clean" mode. Upon completion, the "Cleaning" notification will (should) be turned off.
4) Step 8 "Removing Mineral Deposits" section says to "Rinse by operating the appliance with water at least 3 times."
Now for my review. This is the most poorly designed coffee maker I've ever encountered. The clock doesn't stay on permanently. (Saving energy, I guess?) You need to push the brew button TWICE to get it to start brewing?!?!? What does the "Bold" button actually do? The owner's manual says it will brew "strong" coffee. Is there sorcery involved? Speaking of the owner's manual: Front cover, table of contents: "Care and Cleaning" on page 6? Actually, it's on page 7. No one proofread this. Well, no one with native English skills proofread this. Where did "the serving cup" come from? Love this one: "Make ensure funnel are assembled in place." Where did "funnel" come from? What's funny is that "brew basket" is mentioned in the previous step. The rest of the instructions in this section aren't much better. But it doesn't say how to get the "Cleaning" indicator to turn off. Hmmm. Search the manual some more... Ah, look, back up two pages, under "Using the coffee maker" / "Function selection", it tells you how to get into "Clean" mode and you will notice that it completely contradicts the instructions given in the "Care and Cleaning" section. The "function" instructions have no information on the de-scaling solution.
The best thing I can say about this unit is that brewing temperature is consistently in the 190-195F degree range. But that's pretty standard nowadays, especially for a unit that costs as much as this one does.
