Bosch hot water heater

Posted by dropframe (My Page) on

I am looking for a manual for my W250-4 KV1 B31 S1605 Bosch instant hot water heater. (I find the manual for the W250-2 which does not have electronic ignition)
I particularly need the wiring diagram for the ignitor.

My problem is when I turn on the water, the gas flow starts (I think for the pilot area) and continues for as long as the water is on even though the igniter does not light the flame. This creates a dangerous situation with gas build up in an enclosed area.
