I was looking for a service manual, which you apparently do not supply. I was not looking for someone who will charge me a fee to get information. I can get that info directly from Bosch for free. Thank you for answering. John

Yes. Contact Bosch.
Error codes are considered start-point for troubleshoot.
Tankless are complex electronic machines.
If on-site plumbers cannot figure out problem, then you need trained service technician with a service manual for your specific product, who can ohm-test the electronics.
Bosch will have a list of trained service technicians. And maybe Bosch has another step for fixing problem yourself.
Fix most tankless problems yourself, same day, for $330.
