Thermo coupler may be defective. it controls the main gas valve by closing main if pilot is out. make sure thermo coupler bulb is positioned over and near tip of pilot flame, but not in the flame. Thermo couplers are inexpensive and easy to change out.

Please confirm which model you have. Heading says DSI (electronic ignition) and it sounds like you are describing a manual light with thermocouple?

SOURCE: I have a Bosch Water
Open following link for Bosch tankless troubleshooting resources,
including Bosch contact information, typical manuals, error codes, tech
support, parts, fuel-saver calculator, service bulletins, water heater
forum, fixya links, disclaimers, and links for finding service
Before calling service technician, read manual for fault finding and possible solutions.
Read manual cover to cover, make sure tankless receives yearly maintenance as outline in manual.
Following links talk about keeping pilot lit, and describe location somewhat. Bosch water wizard has standing pilot light.
1) The manual does not show diagrams you asked for.
2) Website that sells Bosch parts does not show parts for water wizard, nor does Bosch site for parts: Instruction manual says: replace pilot injector
3) Searching "pilot injector for Bosch Water wizard" turns up fixya questions which is generally bad news for do-it-yourselfer because it means information sources are through service technician.
4) As a general rule, tankless are not do-it-yourself repairs or installation because they are affected by so many internal and external factors, including air quality, air flow, venting, other gas appliances, gas pressure, gas supply, water pressure, water flow, plumbing problems, water quality, plus internal parts and including any combination of things listed above..
Replacement parts each come will disclaimer.
Add a comment with your experience so others with same-similar problem can benefit.
Send some photos so the internet can see the problem.
Also take advantage of fixya expert assistance live.
For a price, expert works with you while you work on water heater or any do-it-yourself project.
Fixya is always less expensive than a service call.

If it is one of the new ones with the fancy gas control and the blinking light... does the light blink?? or not??
If it is blinking then the pilot should stay lit...
If it will not blink then the sensor is bad or not in the right place...
Or... the gas control is bad... this is happening alot...
If it is brand new... take it back...
