Maybe there are personality differences, and potentially more regional cultural differences within German? Our two APs have been from different parts of Germany -- one from the far north and one from the far south -- but both have been very appreciative and I have never noticed any issues in saying thanks (and we say thanks all the time). It will be interesting to see how it is with our next AP. I do like the idea of being straightforward about it -- it may be a cultural difference but one that can negatively affect relationships.
There surely are regional cultural differences in Germany... but saying thank you is something that you (should) get taught from an early age.
We might say "butter" instead of "Could you please pass me the butter" at the breakfast table but normally a quick "Danke" (thanks) after having the butter passed to you would be expected.
What is true (yes, stereotyping and lumping 80 million people together) is that we often don't do well with praise. We don't get much praise (excelling is expected in middle / middle-upper working class families) and especially not what we consider the over the top praise that is so common in the US. We simply do not learn how to react or respond when being told we are doing great. Usually the answer is nodding and saying okay. Or just nodding. Nodding is fine.
We also don't expect praise or gratitude for things that are expected. If your au pair knows you want her to unload the dishwasher as part of her chores and then thank her for doing it... you are confusing her

. We don't expect any form of appreciation for doing a task we were assigned. Going the extra mile and giving 110%, yes but not for normal day to day tasks that are expected and just part of our job.
So for 09/16/2015 22:17's example "On the weekend, I took her out to eat with some of my kids. The kids thanked me for lunch. She said nothing."
Being taken out for lunch as part of the family is (or can be seen) as part of the au pair program. The host family is also expected to provide the au pair with food (as part of the contract).
When (if) a regular German family, even with adult children, goes out for lunch, it is usually seen as the norm that the parents (especially if they have invited everybody to lunch) pay the food, especially if the adult children are still young enough to live at home. At 18/19 I would never have thought of thanking my mom to pay for my lunch (I was finishing school, I was living with her - feeding me was her responsibility). Now that I am mid 30s and haven't lived at home for 15 years (and am financially independet) I will thank her if we go out for lunch and she pays. Actively saying thank you because your host family provides you with lunch is nothing that is ingrained in us. Now if you had taken her out to her favorite restaurant for her birthday and gotten her a cake then yes, in that case a thank you would be expected in Germany.
She should have caught on to your children thanking you and she should have done as they do but that might currently still need more intercultural skills than she has.
We also don't do "How are you?", "Great, how are you.", "Wonderful, how can I help you today" - because greetings such as that don't exist in German. We say "Hallo", that's about as friendly as we get.
Language is just used differently which leads to a different cultural expectation on how to react in certain situations.
Definitely try a direct approach (we are a direct people, we don't understand "Would you maybe possibly be so kind as to... if you don't mind?" we understand "Please do x" or better "Do x, please", task first, then niceties, if you ask a German if they would mind to unload the dishwasher could well be yes).
Tell her that you need her to be a role modle to your children, how you expect your children to behave in such a situation and ask her to please mirror your (and their) behaviour. Nice but direct will most likely do the trick. As 09/16/2015 16:57 suggested.
I work in retail. Whenever I return from a vacation in the US the customers think I am nuts for being overly friendly. It usually takes me a week to go back to service-desert customer service.
