The glass is a tempered type glass so it probably is compromised and should be replaced.

Induction burners do have a safety thermostat sitting in the middle of the burner that touch the glass to sense overheat situations or boil dry. However if your pot/kettle does not sit flat on the glass (concave bottom) the sensors can be fooled to think the pan is not as hot as it actually is since the sensor cannot get a semi direct read of the surface/bottom of the pan.

Thanks. Kettle sits perfectly flat.

I'd like to see a picture. Melted glass must get pretty hot.

is there a possibility to see the kettle and the damage to it?

Also did finally get someone at Bosch. The cost to replace the glass top is $407 for the part. Plus service. Tech says the same as above. Still some use from the other 3 burners, may be limited on that one (worked yesterday) but the glass is compromised and could fail.

I knew I remembered reading about letting enamel pots boil dry on radient or induction tops here is an excerpt from http://homeguides.sfgate.com/type-pans-radiant-cooktop-84125.html Do not allow porcelain or enamel pans to boil dry since they can melt and stick to the cooktop. Stainless steel and titanium are good choices.

Or

http://homeguides.sfgate.com/enamel-bottom-pans-safe-ceramic-stoves-103918.html

Excerpt: Enamel-bottom pans are acceptable as long as they have thick, flat bottoms and the heating source is radiant rather than induction. You must also take proper precautions to keep contents of the pan from running dry; otherwise, the pans could melt and stick to the surface of the cooktop.

CLEANING AND CARE

Do not bang the teakettle down onto a stove’s surface or work surface. Repeated banging may damage the exterior enamel.

Do not place the kettle on the heat source without having water in the kettle. Never leave a teakettle simmering for long periods on any heat source; it may boil dry, which can result in overheating and damage to the base and enamel.

What's weird is that it did melt the enamel, but the enamel then embedded into the glass. I could scrape the blue off but the damage left a dent.

Lecreuset outlet definitely marketed it as induction safe. Magnet and all. (I obviously didn't read that before though)

and it was just an error. Turned the wrong burner on during dinner. I wasn't even using the kettle.

Can be used on any heat source -

enamel is basically powdered glass that is melted and fused to the metal. If it got hot enough to melt enamel it means it got hot enough to melt glass.

Try calling Bosch again and ask them if you could get some help with the glass. I've seen them help some of my customers on out of warranty product. They may be able to discount the glass for you. You may be able to get it from the customer service rep or may have to ask to talk to a supervisor. Be nice but firm and you may get around a 25% discount. That seems to be around what I've seen happen in the past.

as Jakvis said, that is your best bet. You can replace the glass and if you are handy could probably DIY. The glass is generally $300-$500 depending on the brand/model.
