Product review (1 stars): Or better yet, make a cooktop that doesn't turn off ...
Don't...
buy a Bosch induction cooktop until Bosch explains the conditions that cause the cooktop to automatically shut off at some arbitrary time during use.  This applies to the 500-series, 800-series and Flexinduction models.  I discovered this can happen while reading manuals during my web research on induction cooktops.

Here are the respective web pages and page numbers advising of this stipulation in each model's "Use and Care" manual:

500-series:

I called Bosch Customer Support 5 times over a two-week period and each time talked to a different rep including a Support Supervisor on my last call.  I asked for an explanation about the specific circumstances under which the cooktop would shut off.  I cited several examples of cooking situations where one would not want the cooktop to "just turn off" on its own.  On my last 4 conversations with Bosch support reps, I was told they would research the issue and "get back to me with an answer".

Well, they didn't get back to me, and I still don't have an answer.  The support people don't know and further, they told me they don't communicate with Bosch engineering (who certainly would know the answer).  How strange is that?  But I was copied on an email from a Bosch Senior Support Representative to "an unknown at Bosch".  The email contained the following exact wording from one of the manuals:
"Automatic time limitation
If the element is used for prolonged periods of time without changes in the settings being made, the automatic time limitation function is triggered. The element stops heating. "F8" and the residual heat indicator "H/h" flash alternately in the display. The indicator goes out when any symbol is pressed. The element can now be reset. When the automatic time limitation is activated depends on the selected heat level (from 1 to 10 hours)."

The email also briefly revealed that "a customer" (me) wanted to know the conditions that can cause the cooktop to shut off, but didn't offer any relevant explanations.  Whatsoever!  I was told by a couple of support reps that the cooktop turns off for "safety reasons" but no other details were offered.  Safety reasons?  Really?  Does that mean the cooktops are nearing a dangerous state?  Are these Bosch cooktops the only cooktops ever made that turn off  "for safety reasons"  Maybe, but if so, I'm not aware of any others.

I hope I am not alone in thinking Bosch needs to inform prospective customers exactly what conditions can trigger these (expensive) cooktops to shut off?  Or better yet, just make a cooktop that doesn't arbitrarily turn off.

Bottom line is, buy one of these Bosch cooktops only if you are willing to risk it automatically turning off sometime between "1 and 10 hours".  Or, if you'd be content to just stand watch over it to be sure it stays on while you're cooking a corned-beef for 4-5 hours.

Bosch engineers take notice!
