Hello my name is ***** ***** I look forward to helping you!
I am a Bosch factory trained and certified repair technician
It sounds like the water valve needs rebuilt.
The water valve has a diaphragm in it that engages the gas valve allowing the unit to light. If it has a build up on it or a hole it will not flex enough to engage the gas valve.
You are overriding the water valve. You can only get parts at www.houseneeds.com.
I'd appreciate a five star rating for my advice
